轴类零件在使用过程中会造成轴径磨损,影响正常使用。磨损的轴均可通过修复后恢复使用。修复的方法有堆焊法、镀铬法等,但修复费用高、周期长。用滚花磨削法修复轴件超差部位,经多年使用,效果满意。 具体操作是:清洗轴件两端中心孔,将鸡心夹头套在轴上,再用双顶尖把轴架到车床上。选用节距合适的滚花刀(表1),适当的车床主轴转速和 Shaft parts in the course of use will cause shaft wear, affecting normal use. Worn shaft can be recovered by the restoration of use. Repair methods are surfacing, chrome plating, etc., but the high cost of repair, long cycle. Knurled grinding method to repair shaft over-tolerance parts, after years of use, the effect is satisfactory. The specific operation is: clean the center hole at both ends of the shaft, the center of the chick set on the shaft, and then double-top to the shaft on the lathe. Appropriate pitch knurling knife (Table 1), appropriate lathe spindle speed and
