CNC Machining Materials: Maximum Extents

Find the maximum extents of plastic and metal materials available for CNC milled and turned parts.

 

Maximum extents refers to the raw material and machining envelope. Depending on part geometry and fixturing/clamping requirements the maximum part size may be slightly smaller. For every upload we will analyse and provide feedback.

* 5-axis indexed milling (3 + 2 milling)


What is 3-axis milling?

The 3 axis refer to the X (left-right) Y (front-back) and Z (up-down) movements of the tool. Complex shapes can still be generated like slopes and contoured surfaces. A limitation is that holes and threads typically need to be on one of the 3 axis.

 

What is 5-axis indexed milling? 

5-axis indexed milling is available for all materials. Now, you can machine at any angle, achieving non-orthogonal features like off-axis holes over a much larger part envelope. The result?

  • Increased part sizes to max 254mm x 178mm x 95mm for any material (see table above)
  • More design freedom through oblique machining from any angle
  • Improved milling capabilities for machining complex geometries such as cavities and off-axis holes

 

What is a turning centre?

A turning centre is a lathe, that also has milling capability – this gives you the advantage of much more complex components. The main consideration is designing in a “parting face” this is the last face to be machined and ideally should be flat. This face can be machined with a second setup. See our CNC turning page for more information.
