Company Overview

PCX Aerosystems is a premier supplier of advanced mechanical systems for leading aerospace OEMs. We specialize in highly-engineered precision machining of complex parts from hard alloys like titanium, Inconel & steel, where tight tolerances and quality are imperative. PCX provides integrated special processing services such as heat treating, painting and non-destructive testing. Our capabilities extend to grinding, threading, gear shaping and spline grinding. We also possess large mill turn capability and 6-axis gear shaping using state-of-the art machinery.


Since 1900 our long history of skilled machining has positioned us to become the trusted aerospace supplier we are today.
In 1900 Wilson L. Fenn founded the Fenn Manufacturing Company in Hartford, Connecticut, establishing roots as a machine shop that specialized in plug and ring gages. 40 years later, the company focus shifted to the manufacture of metal forming machines and materials during World Wars I and II.

1939 proved significant – commencing production of complex rotorcraft parts for Sikorsky and ultimately specializing in precision machining services for the aviation industry. By this time, business had converted to 100% military manufacturing. Following these years, the company re-entered the special machinery field while also continuing to supply limited aerospace related components and assemblies.

By 1948, the company purchased Standard Machine Company of Providence, Rhode Island, and was recognized for highly engineered metal forming machinery. With the advent of the Korean conflict in 1950, rotorcraft business increased, allowing for growth in aerospace manufacturing services including rotorheads, transmissions and sub-assemblies.

Throughout the decades, we’ve built a reputation for excellence in precision machining, mechanical systems and rotorhead assembly. We continue to grow and enhance our modern-day product offerings for new rotorcraft while meeting the advanced requirements of the ever-changing aerospace industry.


At PCX Aerosystems our business is expanding. Rapid growth is creating exciting opportunities for highly talented individuals searching for career advancement in the aerospace industry. As a leader in quality precision machining, PCX is actively seeking high achievers who possess technical capability, initiative and drive.

“The breadth and depth of technology opportunities at PCX Aerosystems is like no other business I’ve worked with. PCX is large enough to utilize the most modern technology but small enough that hands on, detailed working knowledge of the technology is required.
-John, IT Director

Having come from a major OEM, I can attest to the many benefits of working in a smaller company but the main benefit is the agility provided in this type of environment. If you have an idea that will positively impact the business, you have the freedom to implement it as long as it’s ethical and you are willing to be held accountable for it. At PCX, your innovation and hard work has a direct impact to the bottom line and to me there is nothing more satisfying than that.
