Abstract
There are advantages of less working procedure and lower cost in cool rolling ball. But after convention heat treatment, because of bigger deformation, the workpiece must be corrected and finely burnish, which improves the cost and descends the precision. Because there is less deformation in laser surface transformation hardening, we use HJ-3 CO2 laser machine to study the technology of the surface phase transformation hardening of cool rolling ball guide-distance is less than 0.1, the axial beat value is less than 0.02mm, surface hardness is above HRc 60 and the average depth of hardening layer is 0.2mm. Not only is it not necessary to correct and finely grind, but also the precision of guide screw is improved.
