CNC Milling Overview

Our CNC milling service transforms basic-shaped stock metals or plastics into more complex geometries with tight tolerances. Using a rapidly turning blade to cut into the raw material, this subtractive manufacturing technology can leverage multi-axis solutions to produce a dynamic range of intricacies and designs.

Advantages

  • Highly Accurate -  Tolerances as low at 0.001"
  • Versatile - Multi-axis cutting allows for highly complex geometries
  • Short-run efficient - Smaller volumes of product often price better
  • High tolerances and fine finishes

Limitations

  • Significant programming needed - Depending on the part complexity and contours
  • Additional setups - Parts with features on all sides can require multiple "setups" and occasionally custom fixtures to hold the work piece in place as it is cut by the milling tool
  • Internal features cannot be machined - if not visible or can be accessed to the tool

Example Machines

  • Haas
    • 3 Axis (vertical/horizontal)
    • 4 Axis (vertical/horizontal)
    • 5 Axis (vertical/horizontal)
