Abstract: The description deals with a facility for dressing of a grindstone (1) for grinding of a running surface structure of a ski, which facility consists of a rotating drive (7) for the grindstone (1), of a dresser (2) adjustable to the circumferential surface of the grindstone (1) and equipped with at least one cutting insert, and of a feed drive (6) for the axially parallel relative movement of the dresser (2) against the grindstone (1). To create favorable construction features it is suggested to provide a controlling system (8) for the feed drive (6) and/or the rotating drive (7), equipped with a control program memory (9) selectable via an input unit (10) and with an evaluation circuit (12) connected to the control program memory (9) for the program-sensitive definition of the position-dependent switching points for the rate of the feed drive (6) and/or the rotating drive (7).
