Abstract

A method for the production of a guide rail for linear guiding and having a hardened rolling body race groove on opposite sides of the guide rail. In order to minimize production costs and avoid cutting of the race grooves, the race grooves are initially spaced at a distance that is greater or smaller than their finally desired value, by an incremental distance. Grooves are provided centrally in the guide rail between the opposed race grooves, and the race rail is then hardened except in the region of the central grooves. Compression rollers in the race grooves or central grooves are then forced into the guide rail to decrease or increase respectively the distance between the race grooves until the desired distance therebetween is obtained. The method can also be employed when only a single race groove is provided on the rail.
