CNC machining is an automated manufacturing process that transforms a solid block or rod of material into a part using end mills. The end mills are controlled by software (G-code) which references a 3D CAD model to reduce the stock material into a desired geometry. Parts can be manufactured relatively quickly due to the level of automation. 

There are many types of CNC machines, which include CNC milling and CNC turning. CNC machining is a suitable manufacturing process for one-off prototypes or custom components as well as mid-volume production quantities.

CNC Machining Capabilities

CNC Turning

CNC turning with live tooling combines both lathe and mill capabilities to machine parts with cylindrical features from metal rod stock.

CNC Milling

CNC milling is a subtractive manufacturing process that uses 3-axis milling and 5-axis indexed milling processes to cut solid plastic and metal blocks into final parts.

Metals Materials

Aluminum

Aluminum is a popular choice for machining due to its low density, good mechanical properties, high thermal and electrical conductivity, and resistance to corrosion. Aluminum alloys, such as 6061-T651, 7075-T651, and 2024-T351, are commonly used in CNC machining because they offer a good balance of strength, machinability, and cost.

Plastics Materials

ABS

ABS is a low-cost engineering plastic that is easy to machine. ABS is an ideal material for structural applications when impact resistance, strength, and stiffness are required. It’s widely used for pre-production prototypes since it has excellent dimensional stability and is easy to paint and glue.
