Precision CNC machining transforms raw material (in the form of finished shapes, cylindrical, or bar stocks) into finished components of various sizes and geometries. CNC machining can produce small or large components with tight tolerances and can be used with a range of materials, from soft aluminum and brass to hard titanium and cobalt-chrome alloys. Secondary operations that can be performed on CNC-machined parts include surface treatment, heat treatment, anodization, and electroplating.
