Peerless Precision, Inc. (PPI) is a small, 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 both 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 Triumph Engine Control Systems and Zygo Corporation 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.
