C-Beam Machine X-Large Mechanical Bundle

The C-Beam Machine X-Large gives you abilities such as plate making, sign making etc. all on a larger scale!



'Its not just a machine, its a solution'

C-Beam X-Large Machine is a CNC machine design based on the popular V-Slot linear guide system. 
The machine is strong as the linear rail incorporates a C shape profile which gives added strength and functionality.


The C-Beam Machine X-Large Machine 
is a collaborative design Build by OpenBuilds Resident Builders Craig Mills & Mark Carew

Many thanks go out to Craig for the incredible work put into this Machine!

  • OPEN SOURCE  - The C-Beam XLarge Machine is Open Source and the Builder community is encouraged to modify and build on this design. 
  • EASY TO BUILD - With the V-Slot Modular Framing System and the detailed Builders Manual, assembly is quick and easy.
  • AFFORDABLE -     OpenBuilds budget friendly parts allow Builders the opportunity to freely create.
  • CUSTOMIZATION -  Take it to the next level and make it your own! Share your builds with the Open Source Builders community


The C-Beam XLarge Machine - the Possibilities are Limitless!

C-Beam XLarge Machine Specs:

  • 750mm x 330mm (29.5in x 13in X&Y axis cut area
  • Usable cut depth is dependent on how you mount your spindle/router, bit length used and spoil board height.
    But as a ball park measurement you are looking at 1 inch (25mm) material. The Z working height is over 2 inches for deep carving
  • The physical footprint is 1000mm x 500mm (with the moving Y table protruding out about 170mm at full travel, front and back)
    with the High Torque Steppers sticking out about 140mm from the frame at the back. Maximum Height ( Z-axis fully up) is about 630mm
  • All the precise Acme Lead Screws are faced away from flying chips to help keep them clean
  • Outside mounted Xtreme Solid V Wheels used throughout for easy on machine adjustment, tuning and strength.
  • Doubled up and adjustable Acme Nut blocks on Y and X axes with a Anti-Backlash Nut Block on the Z axis to reduce/remove backlash.
  • Strong and accurate C-Beamand V-Slot Linear Rail with the new heavy duty C-Beam Gantry Plate XLarge used for all Actuators.
  • Openbuilds Router / Spindle Mount (71mm inside diameter) which works best with the Bosch Colt Router;
    but with some additional shimming, it is also suitable for the Dewalt 611 Router and the 0.8kw Chinese Spindles (65mm diameter).
