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 is by guide means movable in x-direction in the longitudinal direction of the slide surface and by guide means 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.

A method for automatic sharpening the slide surface of a skate to restore the sliding surface after wearing to a desired profile with regard to at least two directions x and y in a coordinate system, one of said directions corresponding to longitudinal direction of the slide surface, using a rotatable grinding wheel, said grinding wheel and said slide surface being movable with respect to each other in said x and y directions comprising the steps of: forcing said grinding wheel in a non-grinding state with a substantially constant contact pressure at measuring points against the slide surface for scanning and determining a plurality of x and y coordinates for the existing profile of the slide surface by moving at least one of said grinding wheel and slide surface with respect to each other in said x and y directions; recording during said scanning the x and y coordinates in a memory; forcing the grinding wheel in rotating grinding state against the slide surface and governing, during the machine grinding of the slide surface, the movement of the grinding wheel and the slide surface with respect to each other in response to signals from the memory estimated by the memory from the recorded x and y coordinates. An apparatus for automatically sharpening the slide surface of a skate to restore the sliding surface after wearing to a desired profile with regard to at least two directions x and y in a coordinate system, one of said directions corresponding to a longitudinal direction of the slide surface, comprising: a rotatable grinding wheel for grinding and for scanning said profile in a non-grinding state, driving means for rotating the grinding wheel, guide means for providing a relative movement between said grinding wheel and the slide surface, in said x and y directions, means for disconnecting said driving means during scanning by said grinding wheel in said non-griding state of the existing profile of said slide surface, means for exerting a substantially constant pressure of the grinding wheel against the slide surface at a plurality of measuring points during said scanning, and for determining x and y coordinates at said measuring points, means for recording in a memory said x and y coordinates corresponding to the scanned profile of said slide surface, means for connecting said driving means of the grinding wheel during a subsequent grinding operation, and means connected to said recording mens for machine grinding said slide surface to a desired profile governed by the recorded x and y coordinates.
