<p>An automatic sharpening of the slide surface of a skate to desired profile with regard to at least two dimensions x and y in a coordinate system is disclosed. A grinding wheel (18, 119) is by guide means (14, 15) movable in x-direction in the longitudinal direction of the slide surface and by guide means (20, 11) movable in y-direction. Firstly, a scanning of the existing profile of the slide surface is carried out by means of the grinding wheel which with a substantially constant abutment pressure forceably is moved along the slide surface, during which movement the x- and y-coordinates of the profile are continuously recorded in a memory. After eventual correction of the coordinates in the memory the grinding is carried out by forcing the grinding wheel in rotating state to repeat the recorded coordinates upon impulses from the memory.</p> |
