Sherline SPI-6730 CNC Upgrade Kit for 4400 Series Lathes

This product does not qualify for free shipping
Note: Upgrade kit is not exactly as pictured. 6730 includes appropriate hardware for upgrading a lathe, not a mill

Any existing Sherline lathe or mill can be converted to CNC-ready status with the available conversion kits listed above. 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 then tapped and the new mount installed. In the case of the mill column and the lathe leadscrew, a new leadscrew must also be installed. Complete instructions for the conversion are supplied with the kits.
