Sherline Lathe Vertical Milling Column 3050-DRO
Lathe Vertical Milling Column
With this attachment, the conversion into a small milling machine from a Sherline lathe can be quick and easy. The attachment consists of a steel dovetailed vertical column with a solid aluminum base that attaches to the bed of the lathe in place of the headstock. The headstock then mounts to a dovetailed saddle on the vertical column. The saddle is raised and lowered to control the depth of cut by turning a handwheel. Calibrations on the handwheel enable depth control to .001″ (.01mm). on the crosslide. If you already have a DRO lathe then this is the vertical milling column for you. This DRO Column features the handwheel, encoder, sensor, and connector and will connect to your digital readout box (not included).
Vertical milling columns now include an oil reservoir on the saddle nut to keep the leadscrew lubricated.
This is the most economical way to get into milling. Most standard vertical milling operations can be performed with this attachment, with size being the basic limitation. Conversion from the lathe to milling takes less than one minute. Almost all Sherline milling accessories may be used with the setup. At a later date, should you wish to upgrade to a complete vertical milling machine, the column will fit the 10″ XY-base or 12″ XY-base. This offers cost savings compared to purchasing a complete vertical milling machine because you save the cost of a second headstock, motor and speed control.
Explanation of Terms
When it comes to the reference to the Sherline product line, a MILL COLUMN is a column used on a mill. It is held in place on the mill base with two 1/4-20 bolts. A VERTICAL MILLING COLUMN is for use on the lathe to add a milling capability. It has a large hole in the center that fits over the headstock pin on the lathe base and is held in place with a set screw. The lathe’s headstock/motor/speed control unit is relocated from the pin on the base to the pin on the vertical milling column saddle. In practice, all vertical milling column bases now have both the single hole for the pin AND the two holes for use on a mill base, so they can be used for either application, whereas mill columns can only be used on a mill base.
