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

We designed our Accu-Pro chucker lathe for our industrial customers who want the convenience of using multiple tools in a single setup. The chucker lathe has an 18″ aluminum base, an 18″ crosslide that accommodates the 3/8″, or 5/8″ gang-tooling tool posts, optional tool posts (tools not included), 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.

This machine is perfect for the customer looking for a benchtop or tabletop machine for making small, precision parts. Our machines are made in the USA, and our customer service is second to none. We have sold many of these machines to medical and high-tech companies and have received great feedback. Although our machines are small, they are capable of producing the same high-quality precision parts that are made on a full-size machine.

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.

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
