ABSTRACT:
An apparatus for abrasive machining of workpieces comprises a base in the form of a carriage, a tool head having a spindle with an abrasive tool fastened thereto, an articulated four-bar linkage, a drive for rotating the abrasive tool and an actuating cylinder for urging the abrasive tool to a workpiece, the actuating cylinder being pivotally mounted on the base and a movable link thereof being pivotally connected to one link of the articulated four-bar linkage. The spindle of the tool head is arranged in a plane of the articulated four-bar linkage and connected to the drive for rotating the abrasive tool through a telescoping cardan shaft to thereby considerably reduce the bulk of the tool head movable parts and improve the tracing of the tool over the surface of the workpiece being machined.
