Teflon work has been a core component of East Coast Precision’s lathe department. Teflon is often used as an insulator in radio connections or as a gasketing material due to its inert qualities.
This is an example of some micromachined Teflon parts we made a few weeks ago. This part was cleanly machined with no burrs in just one operation. We were able to turn, drill, bore, mill a flat, and mill a notch in the part with a single setup.
Here are some small Teflon parts we recently shipped. The first thing to notice is the size of these parts. They feature a blind hole and micro-grooves on the OD. We made a custom ground groove tool so they could be machined with no burrs and come off the machine clean.

This part is made out of Polysulfone. Polysulfone is known for being tough, wear resiting, and high temperature stability. It is also a dielectric material that can be used in capacitors. Dielectric means that it will not transmit electricity.
This part is milled in the milling department here at East Coast Precision. It is approximately 1.5 inches square. It features a milled out body, some threaded holes and a polished top. Due to the geometry, the part is actually able to spring a little bit.
This a sample of some turned Ultem we have been working on at East Coast Precision Manufacturing. Ultem is known for its resistance to chemicals, solvents, and heat. It is often used for instrumentation and reusable medical components. More information about Ultem.
On this part, each end is bored to a very tightly toleranced TIR (total indicated runout). The outside diameter is nicely contoured as well.
East Coast’s machining processes allow for thin walled parts like this to be manufactured very little stress. This makes for a more durable and longer lasting part.
This part is made out a Delrin-AF, a blend of delrin and teflon. The most striking feature is the helical slot that is machined on the OD. The slot width is tightly toleranced at ±.00025. It also features an OD groove and counterbores on each end. Our machining process allows us to produce these parts with minimal to no burrs so secondary operations are not needed in most cases.
