Product Description
This machine is based on our 18″ NexGen 5800-series benchtop 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. The nickel 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.
About the Sherline/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 Touch Controller includes:
- Industrial cable system from the controller to the machine
- 36-volt power supply
- Touch-controller stand

The Axes of Movement of a Sherline 18″ Ball Screw Benchtop Mill.
Click on the image for a larger view.
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).
