Multistage centreless grinding machine - has wheels with frusto=conical surfaces tapering to cylindrical wheels at outlet end

摘要

The centreless grinder has a regulating wheel (22) and a grinding wheel (20) which undergo relative pivoting about an axis near to an outlet end (25). Parts are fed stepwise through stations between the wheels. The grinding and regulating wheels may have frusto-conical surfaces so that a frusto-conical surface produced on a workpiece at one station is engaged along its entire length by the grinding and regulating wheels when it is moved to the next station. The final workpiece surface is ground cylindrical at the station at the outlet end.
