Abstract
The invention relates to a high-hardness roller machining method which comprises the following steps that 1) a roller after quenching is placed on a lathe, the roller is subjected to rough machining with a CBN glomerocryst blade as a turning tool with the cutting speed of 50-90m/min; 2) the roller is subjected to semifinishing with the CBN glomerocryst blade as the turning tool with the cutting speed of 100-180m/min; 3) the roller is subjected to finish machining with the CBN glomerocryst blade as the turning tool with the cutting speed of 200-250m/min. The high-hardness roller machining method has the advantages that the CBN glomerocryst blade can enable heat transmission capacity on the roller machining surface to be small so that the surface quality of a roller product cannot be affected; turning is used for replacing an original abrasive machining, so that machining time is short, efficiency is high, cost is low; the high-hardness roller is subjected to machining in a three-stage-type machining mode, and working efficiency is greatly improved.
