Abstract
A cooling lubricant supply device for supply of a cooling lubricant to a grinding wheel is rotatably mounted as a tool on a grinding spindle of a processing unit in a grinding machine. The device has a feed shoe, which is mounted at least indirectly on a grinding spindle housing and seated on a circumferential surface of the grinding wheel and which has a seating surface facing the grinding wheel. The seating surface has a shape substantially complementary with the circumferential surface of the grinding wheel and is provided centrally with a pocket-like recess into which the cooling lubricant can be fed under pressure. A spring mechanism is provided, by which the feed shoe is biased with the seating surface thereof against the circumferential surface of the grinding wheel.
