The Sherline Lathe Deluxe Vertical Milling Column CNC Ready (Metric) is an innovative attachment designed to transform a Sherline lathe into a compact milling machine. This conversion is facilitated by a steel dovetailed vertical column with a robust aluminum base, which replaces the lathe's headstock. The headstock is then mounted onto a dovetailed saddle on the vertical column, allowing for precise control of the cutting depth through a Zero Adjustable handwheel. This handwheel is calibrated to enable depth adjustments to an accuracy of .001″ (.01mm).
This CNC-ready version is equipped with a stepper motor mount and coupling, prepared for the installation of a NEMA-23 frame-size stepper motor, although the motor itself is not included. The mount features two flanged ball bearings and a preload nut to eliminate end play, ensuring smooth operation. A dual shaft motor is recommended to allow for manual control via the included handwheel when CNC control is not required.
A notable enhancement is the inclusion of an oil reservoir on the saddle nut, which ensures the leadscrew remains well-lubricated. This attachment provides an economical entry into milling, capable of performing most standard vertical milling operations, with size being the primary limitation. The conversion process from lathe to milling is swift, taking less than one minute, and the setup is compatible with nearly all Sherline milling accessories.
For those considering future upgrades, the column is designed to fit either a 10″ XY-base or a 12″ XY-base, offering cost savings by eliminating the need for a second headstock, motor, and speed control. This makes it a versatile and cost-effective solution for expanding milling capabilities.
