CNC milling service
Our CNC milling services allow you to create industrial-grade parts and components with automated speed and precision.
What is CNC milling?
CNC milling is a computer-controlled, subtractive machining process that uses rotating cutting tools to remove material from a solid, stationary workpiece in order to create custom-designed parts. During the milling process, the workpiece is cut along a number of axes to achieve a variety of shapes and geometries.
Our CNC milling service is simple: upload your CAD file to our Cloud Manufacturing Platform™, work with us to optimize your design and choose your material, and then take your project to production quickly and efficiently.
Our CNC milling services
Our CNC machining capabilities include both 3-axis, and 5-axis mills:
3-axis CNC milling involves cutting a stationary workpiece along three linear axes: left-to-right, back-and-forth, up-and-down. Easy to program and operate, 3-axis mills are effective for simple geometric designs and can be used for a wide variety of parts.
5-axis CNC milling expands the design potential of the machining process by adding 2 axes of movement to the workpiece itself. With no need to reposition between operations, 5-axis milling allows for the faster production of more complex parts.
