What is CNC Turning?

CNC turning is a subtractive machining process in which a metal bar or rod is rotated at a high speed while a cutting tool removes material from it. By combining multiple axes of movement and cutting tools and rotating the raw material at a high rate speed, we are able to achieve an almost infinite number of design features for your parts.

Given its speed of production, CNC turning is perfect for rapid tooling and rapid prototyping. The vast selection of materials and finishes that we offer here at W.H. Bagshaw, as well as our strict quality standards, also make our CNC turned parts well-suited for serial production.
