The invention relates to the field of steel rolling machinery, in particular to a roller and a production process for the roller which is made of W6Mo5Cr4V2 
high speed steel; the production process comprises the following steps: a. material preparation; b. the 
processing of two end faces of blanks; c. the 
processing of central holes of two ends; d. the 
processing of rough turn; e. the drilling of hoisting holes outside the length of finished products; f. carrying out 
quenching and 
tempering treatment to cause the roller 
hardness to reach 40 to 50 HSD; g. the modification of the central holes of the two ends; h. the processing of half finish turning; i. coarse 
grinding of the roller body; j. carrying out 
quenching and 
tempering treatment to lead the surface of the roller body to reach the 
quenching hardness of 88 to 93 HSD; k. the processing of the lengths of the two ends to required sizes; l. the processing of finish turning; m. the coarse 
grinding of the roller body and a roller neck; n. 
stress relief treatment; o. the repairing of the central holes of the two ends; p. fine 
grinding of the roller body and the roller neck; q. super grinding of the roller body and the roller neck to finished products. The roller and the production process thereof solves the problem of big size, high production cost, tedious process and great production difficulty of rollers which are produced with conventional materials.
