Product Description

About the Accu-Pro Turn Benchtop Lathe System with Ball Screws

The ball screw lathe design is a reimagined version of our popular 17″ 4400-series benchtop lathe. The lathe has a new solid aluminum base, which creates a very rigid assembly, a beefed-up saddle to accommodate the ball screws, a larger 8″ crosslide, 36V closed-loop stepper motors with #23 NEMA frames, motor mounts with high-torque couplings, and C5 bearings in the headstock for smoother spindle operation.

Ball Leadscrew Specifications

  • Rolled Ball Screw with BSH Nut
  • 10mm Diameter, 2mm Lead
  • C7 Accuracy*, P1 Preload
    *C7 accuracy has a linear tolerance of 50 micrometers / 300mm or .002″ / 12.0″.

The ball screws are only available in metric.

About the Sherline/MASSO CNC G3 Touch Controller

The MASSO Touch Controller with power supply and spindle drive card lets you input data to the controller via a state-of-the-art touch screen. With MASSO, you can write your CNC programs on your computer (Windows, Mac, Linux, etc.) and then transfer your program to the controller via a USB flash drive. You no longer have to use a dedicated operating system like Linux or Mach 4 to control your machine.

The Touch Controller includes:

  • Industrial cable system from the controller to the machine
  • 36-volt power supply
  • Touch-controller stand
