Material for rail of linear guide, rail for linear guide, process of manufacturing rail of linear guide, and linear guide

摘要

A process of manufacturing a rail of a linear guide is described. The process includes preparing a material for a rail wherein the material has a surface formed in a convex shap and two side surface. The method includes a rolling process of forming raceway grooves in the side surfaces of the material and a process for making a mounting hole after the rolling process in such a manner that the mounting hole opens to at least either surface.
