With this attachment the Sherline lathe can be quickly and easily converted into a small milling machine. 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 metric machines). Parts to be machined are mounted on the crosslide.
This is a good way to get into milling. Most standard vertical milling operations can be performed with this attachment, with only size being the basic limitation. Conversion from the lathe to milling takes less than one minute. Almost all Sherline milling accessories can 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 Sherline XY bases (P/N 5200/5210, or 5401/5411). This offers a cost savings compared to purchasing a complete vertical milling machine, because you save the cost of a second headstock, motor and speed control.
NOTE: The column base has offset mounting holes, it is not compatible with XY bases that have inline holes.
A Multi-directional vertical milling column is also available offering all the movements of the Model 2000 8-dierection mill. See P/N 3580/3585.
