通过前两次介绍,我们已知道了在金属切削加工中,所使用的刀具各部分结构等有关知识。但只懂得这些是很不够的。最重要的是如何达到“物尽其用”的目的。也就是说要使刀具发挥更大的潜力,能满足高效率、高质量、长寿命的要求。一把刀具先进与否就是从这几点来衡量的。“刀具大王”金福长师傅设计了很多种式样的先进刀具,可是这些刀具却各有千秋。切削某一金属、某一种工件时刀具先进,而拿它切削另外的金属或另一种工件就会变得不灵。金福长等师傅所以搞了那么多先进刀具,也就是他能够针对加工
Through the introduction of the previous two, we already know the relevant knowledge of the structure of the parts used in metal cutting. But understanding these is not enough. The most important thing is how to achieve the purpose of “make the best use of.” In other words to make the tool to play a greater potential to meet the high efficiency, high quality, long life requirements. A tool is advanced or not from these points to measure. “King of tools ” Jin Fu long master designed many kinds of advanced tools, but these tools have their advantages and disadvantages. Cutting a metal, a workpiece when the advanced tools, and take it to cut another metal or another workpiece will become ineffective. Jin Fuchang and other teachers so engage in so many advanced tools, that is, he can be targeted at processing
