Abstract

A circular grinding machine wherein the upper side of the base for the reciprocable tool supporting unit slopes upwardly from the front side toward the rear side of the base. The headstock and a reciprocable tailstock are mounted at the front side of the base so as to support workpieces at a level above a collecting vessel for spent liquid coolant which is sprayed or otherwise guided against the workpiece during removal of material. The ways for the carriage of the tool supporting unit and the ways for the tailstock are covered by shrouds so that their temperature cannot be influenced by the coolant, and the workpiece which is held between the centers of the headstock and tailstock is located in front of the base so that the major percentage of liquid coolant which descends from the material removing station into the collecting vessel bypasses the base. In this manner, the temperature of the base and/or of the ways on the base is not influenced by the coolant and any coolant which descends onto its upper side flows immediately toward and into the collecting vessel.
