The C-Beam Machine® (assembly required) is a CNC machine designed to be suitable for cutting custom plates and other projects in harder materials.

The C-Beam® Machine is based on the popular V-Slot® linear guide system and uses OpenBuilds C-Beam®, the stiffest V-slot rail to date for its linear actuators. The C-Beam® design incorporates a C-shaped profile and a lead screw based motion system, which gives added strength and functionality. With the correct end mills and settings, the C-Beam® Machine is capable of cutting and milling materials such as:

  • Aluminum and other non-ferrous metals
  • Oak and other hardwoods
  • Plexi-Glass
  • Delrin
  • HDPE
  • Foam
  • Any much more!


The C-Beam machine is modular and based on opensource hardware and design plans, making it easy to modify and configure the machine based on your own needs!
