Abstract (en)

A grinding machine fitted with a control unit suitable to provide the displacement of one or more grinding wheels (1, 2) and with a mechanism (3, 5) for holding and feeding the workpieces (P), in which the grinding wheels (1, 2) are displaced with a feed which is interpolated, according to a programmable law, with the position of the said mechanism (3, 5) for holding and feeding the workpieces. It is consequently possible to obtain a very high precision in the machining of the workpieces, a lower and more regular wear of the grinding wheels and longer intervals between the wheel dressing cycles. <IMAGE>
