Abstract
A method includes producing a preform of a guide rail from steel, putting the preform in a holding device so that the preform is held fixed in position, analyzing the preform held in the holding device, a deviation from a straight shape being measured at a plurality of locations along the longitudinal axis. The method further includes irradiating the preform held in the holding device with a laser beam, a surface section being irradiated with the laser beam along the longitudinal axis at a plurality of locations, respectively on one of two side surfaces facing in opposite directions in relation to the first transverse axis, in such a way that it is heated into the plastic range.
Claims14
A method for producing a guide rail for a linear rolling bearing, comprising:
- producing a preform of a guide rail from steel, the preform comprising at least one running track which extends parallel to a longitudinal axis and is hardened;
- placing the preform in a holding device so that the preform is held fixed in position;
- and
- processing the preform in relation to a first transverse axis, which is oriented perpendicularly to the longitudinal axis, the processing in relation to the first transverse axis comprising:
- analyzing the preform held in the holding device so as to measure a deviation from a straight shape in a direction of the first transverse axis at a first plurality of locations along the longitudinal axis;
- and
- after analyzing the preform to measure the deviation in the direction of the first transverse axis, irradiating a first surface section of the preform held in the holding device with a laser beam along the longitudinal axis at a second plurality of locations, respectively, on one of two first side surfaces that face in opposite directions in relation to the first transverse axis, in such a way that the first surface section is heated into a plastic range, wherein the first surface section is arranged outside the at least one running track, and the one first side surface and a size of the first surface section are selected according to results of said analysis of the preform.
