由于近来冲压精度有所提高,带有爪形零件也能加工了。尖爪部位的几个主要条件有1.爪尖部形状;2.爪面光洁度;3.沿板面的不平度等。一般,用一个工序加工这种零件见图1所示,由于爪部板料金属量微小,所以此部寿命难以保持长久。因此对爪部的尺寸采用研磨法达到。可是研磨加工影响爪部同基准尺寸位置的精度。同时工时增加造 Due to the recent improvement in stamping accuracy, claw-shaped parts can also be machined. Claw parts of the main conditions are 1. Claw tip shape; 2. Claw surface finish; 3. along the board surface roughness and so on. In general, using a process to process such parts shown in Figure 1, due to the small amount of metal plate claws, so the life of this part is difficult to maintain long-term. Therefore, the size of the claw to achieve by grinding method. However, the impact of grinding processing claw with the benchmark position size accuracy. At the same time increase working hours made
