UPGRADE NOTICE: If you are converting a manual mill to CNC, you will also need to purchase the Mill CNC Z-Axis Backlash Adjustment Kit, see details below.

Any existing Sherline mill can be converted to CNC-ready status. The installation will involve drilling and tapping several holes to attach the stepper motor mounts. The kits include drill blocks that are attached to the appropriate table or bed using the single existing hole, and then two new holes are drilled using the block as a guide. The holes are tapped, and the new mount is installed. In the case of the mill column, a new leadscrew must also be installed. Complete instructions for the conversion are supplied with the kits.

NOTE: Any new Sherline machine can also be ordered from the factory with stepper motor mounts already installed. Go to the Lathes or Mills pages for descriptions and prices.

What does “CNC-Ready” mean

CNC-ready means the machine is ready to bolt on stepper motors and apply CNC control to them by means of a system that the user must supply. If you cannot develop your own CNC system, several aftermarket suppliers offer stepper motors, drivers, and CNC software to complete the system. See our CNC Dealers page for links to aftermarket system suppliers.
