Take a look at some more of our work in polycarbonate. This part was turned on a cnc lathe out of polycarbonate, sometimes referred to as lexan. It features a vapor polished finish and concentric grooves on the face. This part is a button that is backlit by a light. It is believed that the concentric grooves will help diffuse the light.
During the initial quoting and machining phase, we worked closely with the customer while they finalized their design. Sometimes that means making a few, sending them out, and waiting to hear back from them. This close relationship is one that not many other shops can offer. The size of East Coast Precision allows us to be nimble when working with our customers.
Our goal is for each customer to feel as if East Coast Precision is an extension of their business and for them to know their parts are as important to us as they are to them.
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 is the machining of the part we first featured on the blog a week or so ago. The process for other materials is very similar. We chose acrylic because the chip we produced was easy to blow off with a blast of air. Other materials would require cutting fluids and would have made it difficult to record and see clearly. Hope you enjoy.
UPDATE: It has come to my attention that the sound track to the video was quite obnoxious. Problem fixed. Apparently, youtube offers stock music for videos you upload. Pretty Cool.
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.
This is an example of some of the Acrylic work we can do in our lathe department.
This part has a few different features. The front face has a knife edge where it blends with the inside diameter. It also has a 3 barbs machined on the outside diameter. There is also a groove and contouring on the rest of the OD.
The inside diameter is drilled thru and features a counterbore on the knife edge (end facing up)
