[Industrial Knowledge] The Benefits of CNC machining Technology Computer numerical control machining, or CNC machining, is the automated removal of material from a block, such as plastic or metal, resulting in a finished part.We can offer fast turn-around, multi-axis, high-speed CNC machining solutions to fulfil most requirements for concept models, prototype parts and low-volume production components. We are able to machine directly from your 3D model and can supply parts from one-off’s, up to low-volume production quantities in a wide variety of materials, including plastics and metal.
