Peerless Precision, Inc. We constantly strive to find better, and more innovative ways to serve our customers in a cost effective manner while maintaining our high quality standard

Peerless Precision, Inc. (PPI) is a small, Woman Owned, 20 person job shop that specializes in the manufacture of precision machined parts for the aerospace, defense, and medical devices industries. We are extremely competent when tolerances of .0001" or better are required and have delivered 1 helium light band in flatness, .000005" in roundness and .003" wall thickness. PPI is certified under bo

th AS9100:2009 and ISO9001:2008. Our services range from prototype through production runs. We also do assemblies and project management. We work with both raw stock (titanium, stainless steel, aluminum, magnesium, carbides, etc.,) and castings. PPI is a dock to stock supplier to Goodrich Aerospace in West Hartford, CT.. We also serve clients such as FLIR Systems, Eaton Aerospace, Kaman Aerospace, L-3 Unidyne, Curtiss Wright Target Rock, Picatinny Arsenal, and many others. Many of the components we manufacture are used in fuel and engine systems. Where companies are looking to consolidate their vendor base, PPI's project management skill in working with over 30 other local precision machine shops offers total, single source capability. Those shops add screw machine, large part manufacture, welding, and much more to PPI's broad internal capabilities. Additionally, PPI works with a firm providing reverse engineering services enabling us to produce low volume, legacy parts at competitive prices.

How Peerless Precision Mastered the Art of Optical Machining

Our precision machine shop constantly seeks opportunities to expand our capabilities and tackle new manufacturing challenges. This drive has been particularly evident in our journey to becoming experts in the niche field of optical machining.

From CNC milling and turning to grinding and assembly, our precision machine shop has the capabilities to manufacture even the most geometrically complex optical components from start to finish.

We're longtime partners with many defense companies, and defense work has even helped determine our company’s direction in the past. When defense customers came to us with a problem, we’ve sometimes looked to new investments to help them solve it in-house. That has directly led to investments in laser welding services and 5-axis machining.

In one case, our customer was performing the laser welding operation before returning the parts to us for final machining and inspection. We brought laser welding in-house to eliminate the need for our customer to perform the operation, reduce lead times, and improve efficiency. That’s the kind of partnership we aim to provide.

Our persistence is made possible by our capabilities, which extend far beyond those of a typical shop. Our precision grinding, honing, and lapping services are increasingly rare in modern manufacturing and enable us to handle precise parts that other shops can’t.

Yet even the finest equipment requires skilled hands; our experienced team knows how to leverage these capabilities to overcome the most demanding challenges.

The Boston Marathon was last month, and even though it takes place on the other side of Massachusetts, a lot of people from our region run it, too. Whether someone runs a fast time or is simply focused on finishing, the story is usually the same: conditions on race day matter, but the real difference comes from the training leading up to it.

Success in manufacturing works the same way. For both quick-turn jobs and long-term orders, our strong performance stems from years of preparation, where we’ve taken on challenges every single day.

On The Blog: How Our Collaborative Approach to Precision Machining Benefits You

In our industry, there is a common disconnect between design and manufacturing. As a result, we often receive part designs with over-engineered or impractical features. For example, unreasonably tight tolerances or unnecessarily strict plating specifications that will increase costs and lead times without any significant benefit to the part’s function.

We are also always on the lookout for opportunities to save you time and money, and often that means speaking up to offer our expert opinion and collaborating with you to achieve optimal results.
