在現代機器工業中,使用了硬質合金刀具以後,可說是機械制造史上的一大革命。高速切削靠着這種具有很堅硬的硬質合金刀具,大大的發揮了吃削量,使產量迅速提高,早日完成計劃。不過這種刀具如磨得不得法,消耗是會很大的。在磨刀時可以乾磨或湿磨,但濕磨如冷切不够的話,還不如 In the modern machinery industry, the use of carbide cutting tools can be described as a revolution in the history of machinery manufacturing. High-speed cutting against this hard carbide cutting tools, greatly play the amount of cutting, so that the rapid increase in production, complete the plan as soon as possible. However, such a tool as worn, the consumption will be great. Grinding can be dry or wet grinding, but wet grinding, such as cold cut enough, not as good
