CNC Machining Processes

CNC Milling

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


CNC Turning

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


Threading Options and Guidelines

For machined parts, you can easily add threaded features, including key and coil inserts. These can be specified within your interactive quote. When a quote is returned, the 3D display will show which thread types are possible for each feature. Different threads (where possible) or no threads can be selected on a feature-by-feature basis.
