#CMT# #/CMT# The method involves producing a guide rail blank (8) by hot rolling and pulling of a metallic material. Side surfaces (2, 3) of the rail blank are formed with guide slots (4, 5), which extend parallel to a longitudinal axis of the rail blank. The rail blank is hardened and subsequently the guide slots are hardened. The guide slots are initially warmly hardened together with the blank. The guide slots are additionally hardened by mechanical cold working. The slots are hardened with a hardness greater than 58 Hardness Rockwell C scale (HRC). #CMT#USE : #/CMT# Method for producing a guide rail of a linear guide. #CMT#ADVANTAGE : #/CMT# The guide slots are initially warmly hardened together with the guide rail blank, and are additionally hardened by mechanical cold working, where the slots are hardened with a hardness greater than 58 Hardness Rockwell C scale (HRC), so that the warpage of the guide rail is avoided, the need of additional processing step for straightening of the guide rail is eliminated, and the stock to be removed is reduced, thus reducing the production cost of the guide rail. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a cross sectional view of a guide rail of a linear guide. 1 : Guide rail 2, 3 : Blank side surfaces 4, 5 : Guide slots 6 : Blank upper side 7 : Blank lower side 8 : Guide rail blank #CMT#METALLURGY : #/CMT# The guide rail is made of material such as tool-steel, chromium and chromium-manganese. |
