CNC Milling

Our CNC milling process produces custom prototypes and end-use production parts in as fast as 1 day. We use 3-axis milling and 5-axis indexed milling processes to manufacture parts from more than 30 engineering-grade plastics and metals. With machined production parts, you can also get more competitive pricing at higher quantities in addition to first article inspection (FAI) reporting, material certifications, and additional finishing options like anodizing and chromate plating.

How Does CNC Milling Work?

We have multiple toolsets based on efficient cutters for a particular plastic or metal material. The machine then rapidly mills parts out of the block in a subtractive manufacturing process that uses either 3- or 5-axis milling.

Machined plastic parts are left as-milled, which typically means they show visible tool marks. Some metal parts allow more finishing choices. When the run is complete and your required surface finish is applied, parts are boxed and shipped shortly thereafter.
