Multicam CNC Wood Router

Multicam CNC Router Y-Axis

This is the Y-Axis ball screw from an older Multicam CNC Wood Router that moves back and forth on top of the X-Axis gantry. These 4mm HIWIN ball screws are generally straightforward to rebuild. Often they can be acquired at reasonable prices when new. However, these components can sometimes can be backlogged for months. Because of this, rebuilding your existing screw may be the only timely option. For your smaller Y and Z axis ball screws, ask us about our fast turnaround mail-in service.
