在加工轧辊时,常需要把辊头的圆周若干等分,然后铣链槽、钻孔或铣梅花瓣。如果工件较重(半吨至拾五吨)那么分度问题很难解决。例如铣四瓣梅花,则需要先把辊头四等分,而一般用划线的办法或用样板加工往往分度不均,而且效率低,劳动 In the processing of the roll, often need to roll the circumference of a few equal points, and then milling groove, drilling or plum blossom petals. If the workpiece heavier (half a ton to pick up five tons) then the indexing problem is difficult to solve. For example, milling four plum, you need to roll the first four quarters, and the general method of using crossed or template processing often uneven, and inefficient, labor
