重磨后的钻头形状不正确,会使孔的加工精度下降,钻头也会很快损坏。美国一家公司采用一种简便的检查钻头形状的光学装置,可以迅速检查钻头重新刃磨后的形状是否正确。新的光学式钻头形状检查装置有两个5倍的放大镜,内置标尺,能检查构成钻头形状的四个方面:1.钻头横刃和沟槽是否位于正确位置; After re-grinding the shape of the drill bit is incorrect, the processing accuracy of the hole will decline, the drill bit will soon be damaged. A company in the United States uses a simple optical device that checks the shape of a drill bit to quickly check that the shape of the drill is reground. The new optical drill shape inspection device has two 5x magnifiers with a built-in scale that checks the four aspects that make up the drill shape: 1. Whether the chisel and groove of the drill bit are in the correct position;
