CNC Machining

What Is CNC Machining? 6

CNC turning produces parts by mounting a blank on a rotating chuck and removing material using stationary cutting tools. This technology is ideal for manufacturing parts with symmetry along their center axis. Turned parts are typically produced faster (and at a lower cost) than milled parts.
