When the Sherline lathe first came on the market over thirty years ago, its use of rigid, extruded components meant miniature machine tools were no longer just toys for producing simple hobby projects. They could now be considered serious machine tools built specially to produce accurate, small parts. Since then, we have not only added a vertical milling machine and extensive accessory line, we have also found ways to improve the accuracy and utility of the tools themselves. The introduction of CNC machines into our production facility has greatly improved the accuracy of Sherline tools. The lathes feature precision rolled leadscrews and handwheels graduated in thousandths of an inch (.001”) or hundredths of a millimeter (.01 mm).
