What is CNC machining?

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. The process, known as subtractive manufacturing, is controlled by a customised computer program and executed through the use of motorised machine tools.

What are the advantages of CNC machining?

At Protolabs we offer quick-turn CNC machining that works well for both rapid prototyping and low-volume end-use components. Our stock of more than 30 engineering-grade thermoplastic and metal materials help make machining an ideal choice for functional testing. And given our hundreds of high-speed CNC machines manufacturing parts in less time than it takes to get a quote from more traditional machine shops, the process helps you stay ahead of schedule.

Milling is a CNC machining process that uses rotary cutting tools, that move along multiple axes, to remove material from a block. Our CNC milling process uses 3-axis milling and 5-axis indexed milling to rapidly cut a choice of more than 30 engineering-grade thermoplastics and metals into complex shapes and precision components.



Turning is a CNC machining process that uses a lathe to create detailed functional prototypes and end-use parts with cylindrical features. Our CNC turning process uses a rod stock, in a choice of metal materials, which is rotated against live tooling to create final parts with axial and radial holes, flats, grooves and slots.



Plastic and Metal Materials

We stock more than 30 engineering-grade plastic and metal materials that are suitable for various part applications and industries. Materials range from plastics like ABS, polycarbonate, nylon, and PEEK to aluminium, stainless steel, and copper.
