Delrin Machining Capabilities

6061 Aluminum CNC Machining Parts
CNC Milling

Delrin is well suited to milling operations. Sharp, carbide-tipped cutters are usually recommended for best results. Since Delrin doesn't tend to melt or deform easily under heat, high cutting speeds can be used.

CNC turning stainless steel machining service
CNC Turning

Delrin can be turned using a lathe, producing parts with excellent surface finishes and tight tolerances. High cutting speeds and feeds can be used due to Delrin's excellent machinability.

CNC drilling stainless steel machining service
CNC Drilling

Delrin can be drilled with standard twist drills. Care should be taken to regularly remove chips from the drill bit to prevent clogging and overheating.

CNC grinding stainless steel machining service
CNC Grinding

Although less common due to Delrin's soft nature, grinding can still be used for very precise shaping and finishing.
