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.

In honor of passing our AS9100 Rev. D audit, we’re featuring an aerospace part this month! We made these CDP amplifier covers from aluminum 6061 using our 5-axis milling and deburring capabilities. They went through inspection before being sent out for Non-Destructive Testing (NDT). Then we gave them an anodized coating before final inspection and shipping.

In precision manufacturing, even the smallest deviation can have a big impact.

That's why every component we machine is produced with careful attention to detail and a commitment to rigorous quality standards. Whether it's a single prototype or a production run, our goal is the same: deliver parts that fit and function as intended.

We’re more than halfway through 2026, and it’s been a good year so far at Peerless Precision. But outside our shop’s walls, manufacturers are facing a growing list of cost pressures. Tariffs, fluctuating material prices, energy costs, inflation, and price increases from outside processors are all affecting manufacturing costs and machine shop pricing.

Those changes are frustrating for customers. And they are frustrating for us, too. Learn how we stay transparent about what has changed and help customers find practical ways to manage those costs: https://bit.ly/4g6F73B

Complex geometries and challenging materials are where advanced CNC milling makes the difference.

At Peerless Precision, our 4-axis and 5-axis milling capabilities allow us to manufacture intricate components efficiently and accurately. We work with a wide range of materials, including aluminum, stainless steel, brass, plastics, steel, and other specialty alloys, transforming raw stock and castings into precision-machined parts built to specification.

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 are necessary to finish parts and produce tolerances as tight as one millionth of an inch.

Based on the needs of your design, we’ll select one of these finishing options:

• Surface grinding
• Cylindrical and jig grinding
• Honing
• Lapping

Keep reading to see how we select the right finishing operation for the tightest tolerances: https://bit.ly/3bXYo5A

At Peerless Precision, we offer a variety of part marking methods, including laser marking, chemical etching, vibro peen, and electroetch serializations. Electroetching, in particular, requires a steady hand and close attention to detail to achieve clear, accurate results on every part.

Before we invested in our 5-axis machine, we successfully machined most parts with our 4-axis mills. But years ago, we added a 5-axis mill as we scaled a complex crankcase project for a customer.

During prototyping, we initially produced batches of 10 using a 4-axis machine. The first operation took approximately two and a half hours, and the second took another 45 minutes. Those cycle times were fine with prototyping quantities, but the customer soon began ordering 50-part batches.

We knew we needed a better process, and we added our 5-axis. With the new machine, the required cycle time was cut in half. The investment opened up new capacity, shortened production time for the customer, and allowed us to take on the larger order.
