APPARATUS FOR CYLINDRICALLY GRINDING WORKPIECES

Abstract

An exemplary apparatus for cylindrically grinding workpieces (60) includes a first holding tool (20), a second holding tool (30), and a first grinding wheel (10). The first holding tool is configured for positioning pre-grinding workpieces, and the first holding tool defines a first groove (24) for containing the pre-grinding workpieces to be partially ground. The second holding tool is configured for positioning the partially ground workpieces, and the second holding tool defines a second groove (34) for containing the partially ground workpieces. The first grinding wheel is configured for grinding the pre-grinding workpieces in the first holding tool. The first grinding wheel defines a first grinding groove (104), and the first grinding groove is defined by a semicircular bottom wall (1042) and two slanted walls (1044) connected with the semicircular bottom wall.
