  • 5 Start Acme Lead Screw Z-Axis
  • All fasteners required for assembly
  • Cable Track (E-chain)
  • Spoil Board fasteners
In addition, our Standard CNC kits are broken down and packed by sub-assembly, helping to make your build straightforward and organized:
  • Machine Base, 4' x 8' (CRP110-00-4896)
  • Machine Risers (CRP120-00)
  • Machine Gantry, 4' (CRP130-00-48)
  • Z-Axis (CRP1040-00)

Product Notes
  1. If you require increased Z-Axis travel, this can be accomplished with our 12" 5 Start Acme Lead Screw Z-Axis by recessing your work-piece in the table, or off the front of your machine (select the 12" Z-Axis travel option below).
  2. If you require increased gantry clearance, our PRO CNC machines feature architecture that can accommodate this.
