5 Time-Saving Benefits of 5-Axis Machining

 

When you need complex parts made fast, you need a machine shop with advanced technology to deliver precision parts with a quick turnaround.

But if the job shop you go to uses 3 or 4-axis machines to make intricate parts, you could be stuck dealing with unnecessarily long lead times.

At Peerless Precision, our 5-axis machining capabilities guarantee high quality and unparalleled efficiency while saving customers time and money.

5 Axis Machining

How Does 5-Axis Machining Differ from 3 and 4-Axis Machining?

In standard 3-axis milling, a cutting tool rotates along the X, Y, and Z axes to remove material from a fixed workpiece. By machining standards, it’s a relatively slow process that’s ideal for machining simple parts.

4-axis machining is the next step up, adding an additional axis of movement to the cutting tool so that it can rotate around the X axis. Unlike with 3-axis milling, the workpiece itself also rotates, allowing for both milling and turning capabilities.

Finally, 5-axis machining adds yet another rotational axis, enabling access to the workpiece from any direction with a single setup. This versatile technology is commonly used to machine high-precision parts with complex features.

5 Time-Saving Benefits of 5-Axis Machining

5-axis machines offer various benefits that decrease lead time to deliver complex parts faster:

1. Reduced need for fixturing.

Since 3-axis machines are unable to rotate parts, special fixturing is required to machine certain features. But on a 5-axis machine, it’s possible to hold a part in one position and rotate it to achieve complex geometries.

5 Axis Machining2. Complex feature capabilities.

Rotating on an additional axis allows 5-axis machines to maneuver complex geometries and tight angles with greater reach and flexibility.

For example, take a look at this cylinder for an actuator assembly. The contours and bosses on this aluminum part would have taken at least four operations on our 4-axis mill. On a 5-axis machine, we are able to achieve the required features and geometries in only two operations.

3. Shorter run times.

5-axis tooling easily reaches all sides of a part, removing material exceptionally fast and cutting slashing cycle times by up to 50%.

We recently machined parts for thermal imaging and night vision cameras for one of our defense customers. Using 5-axis machining capabilities, we successfully reduced first operation times from 2.5 hours to 1.25 hours and second operation times from 1.25 hours to 20 minutes!

4. Smoother surface finishes.

There are 3D milling capabilities built into our 5-axis machines that allow us to achieve extremely smooth surfaces on parts, reducing the need for extensive finishing operations.

Because the part is much closer to the cutting tool than on a 3 or 4-axis machine, we can use a shorter tool that produces less vibration and produces a smoother surface finish.

5. Fewer setups.

Having to manually rotate a part on a 3-axis machine means programming multiple setups to achieve complex features on multiple faces. Not only is this process inefficient, but it also introduces the risk of incorrect alignment each time the part is repositioned.

On the flip side, 5-axis machining accesses a greater number of part faces simultaneously, minimizing the need for setups.

The best thing about 5-axis CNC machining services at Peerless Precision is that you’ll never pay more for this advanced technology. Our CNC milling rate is the same across all machines. So if you see 5-axis machining on your quote, don’t panic! You’ll actually end up saving time and money.

We’re happy to quote your part for you both ways (3 or 4-axis vs. 5-axis) so you can see for yourself the difference that 5-axis machining makes. Request a quote from our MA machine shop today!

The Benefits of Peerless Precision’s In-House Laser Welding Services

At Peerless Precision, we take pride in the relationships we build with our customers. We’re always going the extra mile to keep costs low and lead times short.

Like many other machine shops, it’s not uncommon for us to outsource to trusted vendors for certain services that we don’t have in-house. But we’re constantly looking for opportunities to add to our wide range of capabilities.

Offering as many services as we can in-house at our Massachusetts machine shop helps us control factors like cost, lead time, and quality to improve customer satisfaction.

Last year, we invested in a laser welder to accommodate one of our valued customers. It’s just one example of how far we’re willing to go to meet our customers’ needs.

The Challenge: Customer Was No-Quoted for Laser Welding Services

One of our customers had been relying on our electron beam welding services to fuse two titanium components together. But they ultimately decided that they wanted the parts laser welded instead.

Both welding methods produce high-quality parts, but there are some key differences:

  • Electron beam welding sends a stream of high-speed electrons toward two components. The heat produced from the moving electrons fuses the components together. But because electron beams are notoriously hard to control, welders must use a vacuum setup to concentrate theelectrons, then remove gaseous contamination afterward.
  • Laser welding uses a quick-heat laser that beams photons at the components to fuse them. Because the photons are easier to control,laser welding provides greater accuracy than electron beam welding with less setup and cleanup time.

Laser Welder

The team at our Massachusetts machine shop was well aware of the advantages of laser welding. But we didn’t have that capability in-house.

We attempted to source local laser welding companies on behalf of our customer, but all we got back were no-quotes. The customer’s part had thin walls, which increased the risk of shafts collapsing during the welding process. No one wanted to take on such a risky job.

In an effort to solve the problem, our customer began laser welding the parts themselves. We would ship the customer the components, and they would weld them together, then ship them back to us so we could continue machining.

Although our customer laser welded the parts successfully, it quickly became clear that the shipping expenses and lead times were untenable.

We had a better solution: invest in a laser welder to offer our customer a more efficient process.

The Solution: Peerless Precision Adds In-House Laser Welding Services

Where other machine shops sent back no-quotes, we took on the risk of buying a new piece of equipment so we could weld these challenging parts. Not onlycould we better serve this one customer, but we could also offer laser welding services to many others.

After doing our due diligence, we purchased the Trumpf TruLaser Station 5005, a tool that would allow us to weld thin, strong materials at lightning speeds.

Before offering our new laser welding services, our foreman underwent a rigorous training program with Trumpf to learn how to use the equipment. We’re a training company by nature, so teaching and learning new skills is baked into our culture. Still, Trumpf was by our side every step of the way to answer questions and set us up for success.

With our new laser welder in place, we began completing the entire manufacturing process for our customer in-house, saving them significant time and money.

What it Takes to Machine Mechanical Components for Medical Applications

 

When you need mechanical components for the medical industry, it’s critical to find a machine shop you can trust. There’s no compromising on quality for parts that may be used to support, sustain, or even save people’s lives.

You need to be confident in a shop’s abilities to source high-quality materials, machine parts precisely to specification, and follow rigorous quality control procedures.

Not all shops live up to those standards. . . but Peerless Precision does.

Machining Mechanical Components for Medical Applications

Mechanical Components

We’re an ISO 9001:2015 certified machine shop with trusted processes in place to maintain the highest standard of quality for our customers. Here’s why we excel at machining mechanical components for medical applications:

High-quality materials

We source and buy materials from rigorously vetted vendors that follow ISO 9001:2015 and AS9100D standards. All materials are DFARS compliant—even when it’s not required for an application.

These are the materials we most often help source for manufacturing medical components:

  • Titanium: an extremely strong and corrosion-resistant material found in biomedical implants
  • Stainless steel: a durable and corrosion-resistant material known for being easy to clean and sanitize
  • Invar: a nickel-based non-magnetic alloy resistant to temperature fluctuations, weather patterns, and rust
  • Tungsten: a dense and solid material perfect for radioactive source containers and syringe shields
  • Copper: an antiviral and antibacterial material used on high-touch surfaces
  • Aluminum: a lightweight and strong material used for support equipment like wheelchairs and IV stands

Tight tolerances

Medical devices are delicate pieces of equipment that perform vital functions—and they have no room for error. These parts often need exceptionally tight tolerances to function properly. We’re experts at achieving tolerances ranging from .0001”- .000005”, which components for the medical industry often require.

Our talented team has the craft and experience to achieve tolerances by machine and by hand. So whether we’re relying on our automated CNC machining services or our manual grinding, honing, and lapping capabilities, we’ll shape your part to the exact tolerance required.

Metal finishing

Many parts require metal finishing to enhance surface properties such as aesthetics, adhesiveness, electrical conductivity, wear resistance, corrosion resistance, and frictional resistance.

We use processes like plating, heat treating, and film coating to harden and protect the materials used for medical components.

We perform some finishing services in-house and outsource others to trusted partners. But no matter what, we manage the entire process so you never have to juggle multiple vendors.

Quality Control

Quality is always the top priority at our MA machine shop. It’s especially important when you’re manufacturing medical components. We don’t just maintain an ISO compliant quality system and document all processes. We also machine our parts in an environmentally controlled facility.

This type of environment mimics the environment where our customers inspect and use their parts. All medical components leave our shop rust-free, with no risk of material expansion or retraction. Customers can be confident they’re receiving parts exactly as specified, without any variation from part to part.

How Peerless Precision Selects the Right Finishing Operation for The Tightest Tolerances

 

Did you know that even the most modern CNC machines can’t achieve the extremely tight tolerances needed for certain parts?

In actuality, a wide range of machines and operations, both new and old, are necessary to finish parts and produce tolerances as tight as one millionth of an inch.

At Peerless Precision, we’re experts at achieving the tightest tolerances. Better yet, we reduce risk, cost, and lead time by performing many finishing operations in-house. We don’t need to outsource and forfeit control of our parts like many other machine shops.

So if you need ridiculously tight tolerances on your next project, come to the experts. Then sit back and relax while we take care of the entire process.

How Peerless Precision Produces the Tightest Tolerances

Today, we’re pulling back the curtain on how our team chooses the best finishing operations for super tight tolerances.

We’ll select one of these finishing options based on the needs of your design:

Surface grinding

We use surface grinding when we need to create and maintain a flat surface on your part. The part’s material and your requirements for the desired finish help us determine the amount of material we will need to remove and the correct grinding wheel we will need to use to achieve the desired flatness. Grinding wheels come in various materials and grades, like sandpaper. The grinding wheels (abrasives) we use are selected based on the material we are performing the operation on and the surface flatness/finish we are aiming to achieve.

We also use surface grinding to precision cut pins that can’t be cut with a saw. Saws produce sharp edges and leave lines in the part that make the surface rough and abrasive, which makes it tough to maintain tight tolerances consistently across the part’s surface. For even the tiniest parts, we depend on the surface grinder to smooth things out, finishing edges and removing unwanted rough lines.

Cylindrical and jig grinding

We use these two grinding techniques on the inner or outer diameter of curved, circular parts. Inner diameter grinding is known as ID grinding, while outer diameter grinding is known as—you guessed it—OD grinding. ID/OD grinding options are ideal for completely round shapes.

Jig grinding, on the other hand, can be used on both the inner and outer diameters. It’s perfect for imperfectly round parts. This finishing operation is great for lopsided curves because the machine can hold the part with special fixturing to grind geometrically complex shapes. For example, we recently used a jig grinder on a set of crankcase housings, L-shaped parts with a hole in the middle. Our cylindrical grinder would not have been able to work on this part at all!

Honing

Honing is the next rung on the ladder of finishing operations. More precise than grinding, it allows us to achieve exceptionally tight tolerances of ±.00002” 8 Ra Finish.

Honing is always used on the inner diameter of a part. During this process, a special honing stone is used to maintain concentricity and achieve the desired tolerance.

We know we’ve produced a perfectly honed part when it passes our “drop test.” We drop a pin down the hollowed, honed section to ensure it falls at a certain rate and in precise alignment. If the pin fails the drop test, we hone the part again!

At Peerless Precision, we work with two different technologies for honing. One of our machines is new, but we love our older machine as well—because these machines just aren’t made like they used to be! While the newer NC Hone does the majority of the hard work for the machinist, honing is still very much an art. It requires the ability to “feel” when the parts are getting to the required tolerance. When we are working toward achieving ±.00002”, we might start it out on the NC Hone, but will finish it off on our oldie but goodie. 🙂

Lapping

When you need tolerances as tight as a millionth of an inch, lapping will always be our go-to process (often in combination with honing and grinding).

There are two types of lapping that we perform at Peerless Precision: match lapping and roll lapping. Both use round parts, like roller ball bearings, pins, and pistons. Roll lapping is used when we need to remove millionths of an inch at a time on the outer diameter of round parts. We use various lapping compounds depending on the material. The most commonly used compound is a diamond compound paste, in various grades, dependent upon rough lapping or finish lapping.

Lapping is a technique that’s no longer taught in schools. Most shops won’t even touch parts that require tolerances tight enough to need lapping, and there’s no new technology to replace these older machines.

At Peerless Precision, we’ve put the work in to master this technique. Our experts have years of experience learning on the job and familiarizing themselves with the feel of a properly lapped part. We’re your one-stop lapping shop!

Regardless of the finishing operation we choose, we only quote the processes that are absolutely necessary to achieve the requirements on your drawing. That means if your project doesn’t need lapping, you’re not going to pay for it.Trust the experts at Peerless Precision to determine the proper finishes for your part’s tolerances at the best price. We have the machining know-how to get the job done right using the most cost-effective process. Request a quote today!

Peerless Precision Specializes in Invar Parts for Optical Machining

 

Are you tired of job shops no-quoting you on Invar projects? It’s hard finding a shop willing to machine Invar—let alone one that specializes in this notoriously challenging material.

The nickel-based non-magnetic alloy has many useful properties: it’s resistant to temperature fluctuations, weather patterns, and rust, making it ideal for commercial optics and optical machining applications.

But despite its practical characteristics, there’s no getting around the fact that Invar is difficult to machine. It’s dense, heavy, and extremely receptive to discoloration and fingerprinting, so machinists must take extreme measures to ensure a good cosmetic appearance.

While other job shops balk at Invar, the team at Peerless Precision is prepared to conquer this challenging material! We’re perfectly equipped to handle all of your Invar 36 machining needs, from our machining process to the investments we’ve made to protect Invar parts.

Common Applications for Invar

The commercial optics and optical machining industries regularly use Invar parts inside microscopes due to the material’s non-magnetic properties and resistance to temperature changes. Invar parts are consistently the same size and configuration no matter the weather, which is imperative in optical applications.

Here’s a look at a couple of Invar parts our team made for a commercial optics customer:

Commercial Optics Invar X-Y Modified Retro Holder

Commercial Optics Invar Base Plate X-Y Axis

As you might be able to see in the image, the X-Y Modified Retro Holder has extremely thin walls

measuring only .0500” x .032” thick. Our precision machining capabilities were key to creating tight tolerances for these Invar parts. And the parts are cosmetically flawless, with no visible dents, scratches, or discoloration.

Invar Machining at Peerless Precision

The most common grade of Invar we work with at Peerless Precision is Invar 36. Our machinists describe it as “chewy,” which is their shorthand for “difficult to machine.” Materials that are considered easy to machine usually generate nice, consistent chips during milling or turning. Invar, on the other hand, casts off tiny, inconsistently shaped pellets during machining processes. That makes it unpredictable and harder to achieve that flawless finish optical applications require.

We typically run our Invar 36 parts through several processes to ensure they meet our high quality standards:

  • Milling on our 4-axis or 5-axis CNC mills, depending on the configuration of the part
  • Burring to clean up edges and holes
  • Grinding when we need to smooth out surfaces and finishes
  • Finishing to blast the parts with a glass bead machine for a smooth, satiny finish
  • Nickel-plating to harden the outside of the part and protect it from damage

How Peerless Precision Protects Invar Parts

Since the Invar parts used in commercial optics and optical machining have to be pristine, our team takes extra precautions to ensure your parts are flawless when they leave our shop and when you receive them. Whether it’s additional QA measures or special shipping materials, we do whatever it takes to deliver perfect parts every time:

  • Inspection. During inspection we check for dents, fingerprints, scratches, discolorations, and other imperfections.
  • Packing. Our team wears two sets of gloves and handles Invar parts with the utmost care to avoid adding fingerprints and scratches.
  • Packaging. We package each Invar part in its own individual packing paper, bubble wrap, and box to prevent damage during transit.

Don’t be discouraged by other job shops no-quoting you on Invar parts. Take your next Invar project to a team of experts that specializes in machining this challenging material. Request a quote today to get started!

How Peerless Precision Solves the Problem of Legacy Parts in Aerospace Manufacturing

When planes or helicopters are no longer actively in production, buyers face a unique challenge: when they need replacement parts, the OEMs and general contractors that initially made those parts aren’t available to provide prototypes aftermarket.

Aircraft such as the Bell UH-1 helicopter, Gulfstream IV Business Jet, Piper PA-42 Cheyenne, Saab 340 Twin-Engine Turboprop and Rolls Royce RB211 engine may still be in use, and in some cases sold commercially, despite being out of production. Depending on their condition, buyers may require replacement parts to restore these vessels—and the replacements must be comparable in quality to the original market components.

Peerless Precision is an AS9100/ISO9001 certified aerospace manufacturer. Our quality certifications allow us to approach challenging parts with the utmost confidence, including making legacy parts for aerospace manufacturing.

The Challenges of Manufacturing Aerospace Replacement Parts

The aerospace industry enforces stringent standards for the manufacture of parts and components. Parts must be able to withstand extreme temperatures and pressures while maintaining exceptionally low failure rates. Even the slightest miscalculation can have devastating consequences.

When an aircraft or its systems go out of production, it becomes a legacy product, along with its specific build information. The precise materials, specifications, and design elements can be lost in time. At Peerless Precision, we have extensive experience working with aftermarket reverse engineering firms that seek out these legacy products and work with the FAA to obtain the necessary Parts Manufacturer Approvals (PMAs). Through these types of partnerships, PPI has the ability to manufacture these legacy components.

Working with Peerless Precision for Aerospace Replacement Parts

Peerless Precision is perfectly suited for legacy part production for aerospace machining, promising our customers:

  • Quality parts. We produce parts with extremely tight tolerances ranging from .0001”- 000005″ and have the right certifications to ensure the highest quality standards.
  • Low volumes. Whether you need one part or a small inventory for customers to get spares as required, you’ll benefit from working with a job shop that specializes in low-volume production.
  • Competitive prices. Our experienced team and highly efficient processes allow us to optimize jobs for cost. We’re always willing to work with customers to meet pricing demands.
  • Supply chain consolidation. We work with a local reverse engineering firm for aftermarket prototyping. Through this process, we can determine how to precisely replicate a part, managing the modeling and FAA approval process for you.

When you need a trusted job shop to meet stringent industry requirements for flight-ready replacement parts, our team of experts is at your service. Request a quote, and we’ll get back to you within 24 hours.

Benefits of In-House Mechanical Subassembly

 

One of the best ways to consolidate your supply chain is to find a precision machine shop that can also do assembly work. At Peerless Precision, not only do we make your parts, we can put together various components in even the most complex mechanical subassemblies.

We often see our customers relying on their in-house engineers for subassembly or hardware installation after parts have been machined. Although engineers understand what components are needed for form, fit, and function, there’s only so much that they can accomplish without specialized equipment, working at their desks.

While early prototypes might be assembled by our customers, assembly is not the best use of an engineer’s time, energy, and skills as a part moves into later prototyping and production. When subassembly is removed from the engineer’s workload, it allows them to focus on design and functionality—or to move on to the next big project!

Peerless Precision is an Expert in Mechanical Subassembly

Our team specializes in mechanical subassembly; this process is not the assembly of a finished product, but involves putting together several mechanical components that go into a larger system. When you choose a machine shop with expertise in mechanical subassembly, you consolidate your supply chain. That often leads to reduced lead time and lower costs—without any compromise on quality.

Our capabilities in medical machining landed us a subassembly project for a mechanical prosthetic shoulder. We machined every single part for this prototype and delivered it to our customer fully assembled.

For aerospace machining, optical machining, and the defense industry, we offer matched valve and sleeve (or piston sleeve) subassembly. Both industries require extremely tight tolerances and often involve very tiny components. This type of subassembly is nearly impossible to do without the highly specialized tooling and equipment we have in our MA machine shop.

Subassembly Hardware Options

At Peerless Precision, we can assemble components by buying standard hardware, modifying existing hardware, or custom-making unique hardware for your project.

Whether the assembly requires tight tolerances, tiny components, or both, we’ve invested in the tooling and equipment to get the job done right. We source and/or manufacture all kinds of hardware components for subassembly:

  • Helicoils
  • Screws
  • Nuts
  • Bolts
  • Pins (including, but not limited to Headed Pin, Modified Diamond Pin, Headless Straight Pin, Spring Pin, Dowel Pin, Expansion Pin)
  • Threaded inserts
  • Plugs
  • Clamping plates
  • Locked-in studs

While our customers are welcome to choose their own supplier for standard hardware, whenever we have a choice, we go with Atlantic Fasteners. This company has a great variety of high-quality hardware, ships fast, and is local to our Massachusetts machine shop. (We can literally drive there and pick up the order if needed!)

We regularly use the expertise of our distributors to make recommendations, choose the right hardware based on price, lead time, and specifications. We choose hardware that’s made in the USA whenever possible.

Obsession with Quality Control

At Peerless Precision, we go to great lengths to ensure quality for every part that is machined in our shop. We inspect every component in a subassembly multiple times to make sure we meet our own quality standards as well as those required by our AS9100 Rev. D and ISO 9001:2015 certifications.

When you have parts that need to be assembled, let us deliver them ready for installation. Get a quote for your mechanical subassembly today.

Peerless Precision Provides Unique Capabilities for Optical Machining

 

Optical measuring systems and 3D measuring systems are expected to consistently deliver extreme accuracy and precision. To do so, the internal parts and components in these devices must be reliably manufactured to extremely tight tolerances. Parts that aren’t made to the exact required specifications can result in tolerance stacking and lead to significant reading errors and improper function of the optical equipment.

When this kind of complexity is involved, you need a shop that has optical machining experience to make sure the job is done right.

At Peerless Precision, we have more than 40 years of experience in custom optical machining. Our technical experts can manufacture optical measuring equipment parts of any shape or complexity. We’re one of a handful of precision machine shops in the U.S. that is capable of creating the internal parts and components required for 3D measuring systems and larger-than-life microscopes.

Peerless Precision Knows Optical Machining

We work with tough materials. At Peerless Precision, we’re not afraid to work with tough materials—titanium, tungsten, and even invar—that are used in optical machining.

Many shops try to avoid using these materials, which can be difficult to work with and hard on tools and machines (earning their reputation as “chewy”). We’ve got both the tools and the expertise to offer these capabilities. We also rely on tooling suppliers’ advice on how to best machine unusual materials, maintain the long life of our tools, and run our machines with maximum efficiency. That’s how we keep our costs (and our quotes) down and our lead times as short as possible.

We’re experts in thin wall machining. Some of the components in optical equipment are as thin as tin foil. We’ve got the capabilities to create thin walls, even from challenging materials like titanium, that are just .003” thick.

We achieve extremely tight tolerances. Technically, a part is considered to have a tight tolerance if its permitted variance is +/- .002-.001 inches. Due to its precise measurement systems, optical machining requires much tighter tolerances than standard machined parts. . At Peerless Precision, we’re able to achieve extremely tight tolerances ranging from .0001”-000005”.

We know cosmetic appearance is crucial. We have an extremely high level of quality for the aesthetics of our customer-facing parts. We make sure there are no nicks, dings, scratches, fingerprints, or discolorations. During inspection, we hold the parts under a light that is as bright as the sun to ensure they are pretty, shiny, and perfect. If you line 10 components up on a shelf, all 10 will look identical.

Case Study: Coldfinger Weldments

Coldfinger (coldwell) weldments are a critical mechanical component for optical machining. We currently manufacture coldfinger weldments that are used in submicro cryogenic cooling systems for infrared, night vision, and thermal imaging equipment.

The weldments we make consist of two separate components, base and end cap, which are individually matched prior to welding. In order to match, there can’t be a gap between the two components: they must be able to come together with a light press fit so the end cap won’t fall off of the base if it’s inverted. Using a light press fit also keeps the components from fitting too tightly, which could cause a distortion of the internal diameter after the welding process.

(left to right): base and end cap, setup for laser welding, welded parts (Images:

Not only have we been making coldfinger weldments for more than 20 years, we even purchased a laser welder specifically to weld these components and further expand our capabilities for optical equipment.

Peerless Precision is a Top Supply Chain Manager for Tier 1 Suppliers

 

Tier 1 suppliers know the advantages of reducing their supply chains: a more streamlined process, time and cost savings, and less stress.

But not every machine shop in MA has the ability to successfully manage a supply chain, particularly for aerospace manufacturing, medical manufacturing, and defense manufacturing, which carry the highest quality standards. Some shops simply don’t want to be the middleman. Others don’t want the responsibility of managing the work of other vendors.

Peerless Precision is uniquely poised to be an excellent supply chain manager for Tier 1 suppliers. Our experience, organization, and fanatical commitment to quality set us apart from other shops.

What’s involved in supply chain management?

A finished part may look simple enough, but most machined parts go through multiple steps (and many more operations) before they’re complete.

A typical part might go through the following processes, all of which could be managed by the customer—or outsourced to a supply chain manager:

  • Material sourcing and purchasing
  • Heat treating
  • Machining (i.e., CNC milling and CNC turning)
  • Finishing
  • Laser engraving or marking
  • Mechanical assembly or hardware insertion
  • Quality inspection

There is often shipping, transport, and coordination between every single phase! That’s a lot of moving parts for an engineer or buyer to keep track of. And if there’s any lag time or lack of communication between vendors, it can cause major delays.

Benefits of Supply Chain Management

Working with a manufacturer who also manages the supply chain has significant advantages. You’ll reduce quality issues, decrease lead times and even cost, and save a whole lot of energy. Key benefits of supply chain management include:

Project Management. Instead of directly managing several different manufacturers and subcontractors, we can manage part or all of the process for you. Those services could include:

  • Maintaining and managing inventory
  • Coordinating shipping and tracking
  • Managing deadlines and providing just in time delivery

The administrative pieces of supply chain management add up quickly, and delegating your project management to Peerless Precision can save you valuable time and energy.

Quality Control. Supply chain management only works effectively if you trust that the end result will be perfect parts, delivered on time—every time. That’s why quality is so important to us. We perform all inspections (source inspection, first article inspection (FAI), final inspection) in house.

Everything that enters and exits our shop is personally inspected by our team, and nothing leaves our facility that isn’t 100% perfect. We also hold several quality certifications: AS9100D and ISO9001:2015 for aerospace machining and medical machining, as well as ITAR registration for defense machining.

Cost Reduction. At Peerless, we can save on cost in a few ways. First, we have the ability to do many operations in-house (ask us about the laser we invested in so that we could provide an in-house solution for customers and expand our capabilities). We may be able to negotiate better pricing with subcontractors based on the overall volume of work we send to them, where you may only have leverage based on your own order. And by working with local vendors, we can often cut down significantly on transportation and shipping costs.

Shorter Lead Times. Time is money. When we manage all or part of your supply chain for you, we’re always looking ahead to anticipate the next step in the process. We do all of our laser engraving in-house, so that cuts out the outside step and reduces lead times significantly (by as much as 50%!).
