Abstract
In order to grind bar-shaped workpieces which have a non-circular cross-section and flat faces which are parallel to each other, two partial operations are performed consecutively. First, the bar-shaped workpiece is rough ground and finished on the faces by way of double-disk face grinding. The bar-shaped workpiece is clamped on the longitudinal sides in the first clamping position thereof, and the bar-shaped workpiece is transported between two clamping jaws, which clamp the workpiece in the second clamping position thereof on the faces. The first clamping position is then released, and the bar-shaped workpiece is rotated by the clamping jaws. A CNC-controlled peripheral grinding step is performed based on CX interpolation principles. This rough grinds and finishes the longitudinal sides of the bar-shaped workpiece. Transport from the first to the second clamping position is effected by a clamping station, which concomitantly forms the holder for the face grinding operation.
