焊接硬质合金刀片的车刀在一般工厂中使用已很普遍了,但是它的刃磨还存在着不少问题。用绿色碳化硅砂轮磨削时效率低,磨屑多,操作条件差。由于砂轮比较容易磨损,刃磨刀具前面和断屑槽往往很困难。并且磨出的刀片刃口易产生裂缝和缺口,会影响刀具的切削性能和使用寿命。机夹不重磨刀具是近年来国内各工厂重点推广的先进刀具。对于这种刀具所用的刀片来说,虽然它的名称是“不重磨”,但通过实践证明对它进行重磨使用才是比较经济的。并且
It has become commonplace to use a tungsten carbide blade turning tool in a typical mill, but its sharpening is problematic. Grinding with a green silicon carbide wheel low efficiency, wear debris, poor operating conditions. As the grinding wheel is relatively easy to wear, it is often difficult to sharpen the front of the tool and the chip breaker. And grinding blade edge easy to produce cracks and gaps, will affect the cutting tool performance and service life. Machine folder is not resurfacing knives in recent years, the focus of the domestic factories to promote the advanced tool. For the blade used in this tool, although its name is “no regrinding”, it has proved to be more economical to regrind it. and
