CNC machining is a widely used manufacturing process for metal and plastic parts. It is known for its precision, repeatability, and ability to produce strong and durable parts from extruded blocks of material. It can also be used to make parts in a short timeframe, since no tooling is required, but produces parts of a higher quality than other short-turnaround technologies like 3D printing. For all these reasons, CNC machining is highly suited to the prototyping and production of components for electronic devices, from simple handheld devices to expensive pieces of industrial equipment. Components large and small, simple and complex can be CNC machined, and these are just a few of the most widely made.
