Klein Maschinenbau GmbH U.
Co. KG, Germany
Currently, as never before, there is an
ever-increasing demand for higher workpiece accuracies. An amount of workpieces
can only be produced using the current machine parks after undergoing very
exacting set-up procedures and thus long change-over times.
Together with
the dead centre point of the external grinder the centre hole forms a plain
bearing. For optimum results the taper of the centre hole must be round and
co-axial with the centre hole at the other end of the workpiece.
Klein Maschinenbau GmbH U. Co. KG – Center Grinding Machines
After hardening the workpiece, its centre holes are neither round nor oval, are out of alignment, covered with scale and too rough. To obtain good results rapidly in circular grinding – essential for productivity – the centre hole must be ground by a Klein Centre Hole Grinder before they are mounted on the external grinder.
