在用万能夹具进行成型磨削中经常会遇到须磨削大小不同的凹凸弧。我们车间研磨组老工人张吉庆设计制造了一只简易精密砂轮打圆弧工具,如图所示。它可以打出R0.5至R15的大小不同圆弧。在实际的使用过程中,效果很好。磨出工件的圆弧不论在精度及光洁度方面都比手拿着金刚笔 In the use of universal fixture for forming grinding often encounter different sizes of concave and convex arc to be grinding. Zhang Jiqing, an old worker in our grinding shop, designed and manufactured a simple precision grinding wheel arc tool as shown in the picture. It can play different arc sizes of R0.5 to R15. In the actual use of the process, the effect is very good. Grinding the workpiece arc in both precision and finish than holding a diamond pen
