Teflon rod material in the mechanical processing how to get the surface smoothness and clean surface
?In the mechanical processing to pay attention to the requirements of four aspects: processing PTFE requires a sharp tool sharpening, it can not use carbide cutting tools, because the carbide cutter can not sharpen the sharp; second can not add coolant ; The third must have a reasonable speed (through the test); the last point to have a reasonable knife depth and feed (through the test). The surface roughness problem solves the problem that the surface must be clean.
At the same time, keep other excellent PTFE performance. Filling varieties are glass fiber, metal, metal oxide, graphite, molybdenum disulfide, carbon fiber, polyimide, EKONOL, wear resistance, limit PV value can be increased by 1000 times.
Polytetrafluoroethylene is a polymer of tetrafluoroethylene. Teflon (Teflon or PTFE), commonly known as "plastic king", Teflon has excellent excellent overall performance, high temperature, corrosion resistance, non-stick, self-lubricating, excellent dielectric properties, very low coefficient of friction The The addition of any filler to PTFE that can withstand the sintering temperature of PTFE has a significant improvement in its mechanical properties.
