Delrin Machined Spare Parts by CNC Machine
Feature:OEM service
We are a company specialsing in making OEM mechanical parts in rubber & plastic&metal material, and we produce according to your samples or drawings ,if they are not available, we design according to your requirements and the application.
The machining processes
1.Turning: For parts which have high surface requirement, wide-head cutters are better. When processing thin walled and soft material, cutters like knife are recommended.
2. Milling: When milling the surface, end-milling is more cost-effective than circular milling. For circular and forming cutter, it should have less than two cutter edges. In this case, the tolerance caused due to the edge vibration can be lowered to the minimum.
3. Sawing: Thin saws are usually used to saw thick parts to avoid the heating caused by friction. It would be better to use sharp and big sawblade.
4. Drilling: When drilling the solid materials, make sure to use sharp drill, otherwise the increasing pressure during drilling will cause material cracks.
The common document files accepted are : *.pdf/*.dwg/*.IGS/*.step/*.prt/*.sldprt Just send the drawings to us, we will handle the rest for you.
