Precision Custom CNC Parts, Built to Your Specs

From rapid prototypes to low-volume production, we deliver tight-tolerance custom CNC parts for aerospace, medical, semiconductor, and automotive industries — with lead times as fast as 3 days.

Swiss Machining Parts

Our Swiss-type CNC lathes utilize a sliding headstock and guide bushing system that provides exceptional rigidity for long, slender parts. The workpiece moves axially through the guide bushing while cutting tools remain fixed at the point of support—eliminating deflection even on length-to-diameter ratios up to 20:1.

CNC Turning and Milling Parts

Our MAZAK mill-turn centers and Citizen BNC series combine CNC turning and 5-axis milling capabilities, eliminating multiple setups and handling errors. This hybrid approach delivers complex parts faster, with superior accuracy and surface finish.

Custom CNC Parts Materials

We manufacture custom CNC parts from a wide range of materials, including metals (brass, stainless steel, aluminum, titanium, copper alloys, and exotic alloys), plastics, and specialty materials. Material selection for custom CNC parts depends on machinability factors such as hardness, thermal stability, and chip formation behavior. Below is a full list of materials we work with.

What is Swiss Machining?

What is Swiss Machining?

Swiss machining uses a sliding headstock and guide bushing, unlike standard lathes, to support material while the tool remains stationary.
