我们需要磨削许多淬火钢的刀具或成形块,其形状如图1所示。用圆弧形打磨器修整砂轮后,就可以在平面磨床上,用纵向进给磨削这种工件。但是,这种方法会导致花费许多修整砂轮的时间及调整时间。而且砂轮损耗很大。作为一种改进,制造了一种如图2所示夹具,它用于外圆磨床上磨削,夹具两端都有中心孔,夹具的各个表面都经过磨光。不用移动夹具中的工件,就可以使安装在夹具上的 We need to grind a lot of hardened steel tools or forming blocks, the shape shown in Figure 1. After dressing the grinding wheel with an arc-shaped sander, it is possible to grind the workpiece on a surface grinder with a longitudinal feed. However, this method can result in a lot of time and adjustment time for dressing the grinding wheel. And the wheel is very expensive. As an improvement, a jig as shown in FIG. 2, which is used for grinding on a cylindrical grinder, has a center hole formed at both ends of the jig, and each surface of the jig is polished. Do not move the fixture in the workpiece, you can make the fixture installed
