Product Description

The 4th Axis for your Accu-Pro VMC Ball Screw Mill with MASSO Touch Controller

The CNC Rotary Table with 36V Stepper Motor* comes equipped with an A-axis output cable ready to drive a 4th rotary axis. This rotary table is all you need to turn your Sherline Accu-Pro mill into a 4-axis machine. Just plug the A-axis cable from the stepper motor into the A-axis input on the MASSO G3 touch controller. The software handles G-code for the A-axis, and numbers entered after the letter “A” in the code represent rotational degrees.

The CNC rotary table includes a MASSO homing sensor

*NOTE: This CNC rotary table works only with the MASSO G3 Touch Controller. The 36V stepper motor is powered by the 36V power supply from the MASSO controller.

  • Horizontal orientation—50 lbs.
  • Vertical orientation—30 lbs.
  • Vertical rotational torque—6 foot/lbs. (meaning it can lift a 6 lb. weight when suspended 12″ away from the center of the rotary table)
