Abstract
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.
Claims3
A process of manufacturing a rail of a linear guide, comprising:
- a preparatory process of preparing a material for a rail of a linear guide, said material having a surface being formed in a convex shape and two side surfaces;
- a rolling process of forming raceway grooves in said side surfaces of said material prepared in said preparatory process;
- and
- a hole-making process of making a mounting hole after said rolling process in such a manner that said mounting hole opens to at least either said surface or a surface opposed to said surface.
A process of manufacturing a rail of a linear guide, comprising:
- forming raceway grooves in a material having a convex top surface by rolling two mutually parallel side faces of the material;
- and
- providing a mounting hole, said mounting hole opening at least to a surface which is on a mounting side of the rail provided between said two mutually parallel side faces along a direction in which said raceway grooves extends.
A process of manufacturing a rail of a linear guide comprising:
- providing a material from which the rail is formed, the material having a convex top surface and two side surfaces;
- and
- deforming the convex top surface by rolling a raceway groove in each of the two side surfaces.
