Sherline Accu-Pro VMC Mill

The Sherline Accu-Pro VMC Mill 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.

Sherline Accu-Pro VMC Mill

This machine is based on our 18″ NexGen 5800-series mill. The 18″ mill base with ball screws comes with all-new saddles developed for the ball screws. The X/Y-mill saddle has been beefed up to accommodate the larger ball screws, and it has an electroless nickel/Teflon coating. This coating offers a hard surface that is rustproof, while the Teflon provides a friction coefficient of .1-.2u for smoother movement of the saddle and the table. The Accu-Pro Mill also includes 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.

MASSO CNC G3 Touch Controller

The MASSO Touch Controller with power supply and spindle drive card allows you to 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. No more having to use a dedicated operating system like Linux or Mach 4 to control your machine.

The Axes of Movement of a Sherline 18″ Ball Screw Mill.

The table left/right movement is referred to as the X-axis. The table in/out movement is the Y-axis. The headstock up/down movement is referred to as the Z-axis. The headstock can also be rotated on its saddle on Sherline mills (#4), the column ram can be moved in and out (#5), and the Z-axis column can be tilted forward and back (#6).
