Work-piece grinding method e.g. using rotary grinding disc, involves angularly displacing spraying medium to contact point on grinding surface relative to axis of rotation of grinding disc

摘要

A method for grinding/cutting a work-piece using a rotary grinding disc (1), in which in relation to the rotational axis (2) of the grinding disc (1), angularly offset to the contact point, a spray medium is sprayed on to the effective grinding surface of the disc so that at least one spray nozzle (5) periodically covers the whole effective grinding surface, mainly transversely to the direction of the peripheral speed of the grinding disc (1). An independent claim is also included for a grinding device.
