Method for the production of a guide rail

In a method for the production of a guide rail for linear guides in which at least one hardened rolling body race groove is provided, the improvement wherein race grooves are formed of race inserts of hardened material held by a guide rail body of substantially easily workable material more easily workable than said hardened material, with the distance between the opposite race grooves being slightly larger than a desired distance A by a dimension x, and thereafter moving compression tools in the race grooves until the distance between the race grooves is reduced to the dimension A.

A method for the production of a rail for a linear guide for rolling bodies, wherein a linear groove is provided extending along a first edge of said rail in a first given plane, said rail having a second edge opposite said first edge and in said first plane;

• said method comprising providing a pair of elongated recesses on opposite sides of said rail, spaced from said first and second edges and extending coextensively with said linear groove, then hardening said first edge in the region of said linear groove without hardening said rail in the region of said elongated recess, and then compressing said rail in a direction parallel to said plane by urging a compression roller in said linear groove to reduce the distance between said first and second edges to a determined dimension.

• said method comprising providing a pair of elongated recesses on opposite sides of said rail, spaced from said first and second edges and extending coextensively with said linear groove, then hardening said first edge in the region of said linear groove without hardening said rail in the region of said elongated recesses, and then compressing said rail in a direction normal to said plane by urging opposed compression rollers in said elongated recesses to increase the distance between said first and second edges to a determined dimension.

A method for the production of a rail for a linear guide for rolling bodies, wherein a linear groove is provided extending along a first edge of said rail in a first given plane, said rail having a second edge opposite the first edge and in said first plane;

• said method comprising providing an insert in said first edge of said rail of a material that is harder than a material of said rail, to define a linear race for rolling bodies, said insert defining said linear groove, and then compressing said rail in a direction parallel to said plane by urging a compression roller in said groove to reduce the distance between said first and second edges to a determined dimension.
