Product Description

About the 12″ MASSO CNC Mill System with Ball Screws

This machine is based on our popular 12″ Deluxe 5400-series mill. The 12″ 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 new ball screw design for the column saddle reduces the overall Z-axis travel by 1.4″. Because the ball nut does not allow the column saddle to move down as far as the old style column saddle, we recommend upgrading to the 15″ mill column. This will allow you to move the headstock closer to the top of the mill table. However, you will still lose 1.4″ of overall travel in the Z-axis.

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, so the numeric graduations on the handwheel dials are 2mm per revolution and .02mm per line.

About the Sherline/MASSO CNC Controller

The MASSO controller allows you to 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 to control your machine.

This set up includes our 4-axis CNC driver box.
