Centre Grinding Machines
There is an ever-increasing demand for higher workpiece accuracies.
Running on the dead centre tip of the external grinder the centre bore forms a plain bearing that directly effects the roundness of ground external diamters. For perfect results the taper of the centre bore must be round and co-axial with the centre bore at the other end of the workpiece.
After heat treatment the workpiece centre bores are often out of round or oval, out of alignment, covered with scale and too rough. To obtain good results in cylindrical grinding the centre bores must be ground or lapped by a Centre Grinding Machine before they are presented to the cylindrical grinding machine.
We offer Centre Grinding Machines made by the renown German manufacturers Henninger and Klein
