东京芝蒲电气公司,把原来的超硬一次磨损镶刀片(即使坏后丢掉的镶刀片),小形化和轻量化,研制了“节约型切削工具”,可以大幅度地节约原料,其作法有把原镶刀片减小三分之二使之小形化和在镶刀片中部位开设大的空洞使之轻量化两个类型。这些作法都可以使材料大幅度地减少30～70％,而且镶片刀具的切削性能与原镶片刀具比较并不逊色,可以预测,新型镶刀片完全能够满足实用的要求。 Tokyo Shibaura Electric Company, the original hard one wear the inserts (even if lost after the bad insert), small and lightweight, developed a “saving cutting tools”, can greatly save raw materials, the practice of The original insert to reduce the two-thirds of the small shape and the insert in the middle part of the hole to make it lightweight two types. These practices can greatly reduce the material by 30 to 70%, and cutting tool cutting performance compared with the original veneer tool is not inferior, it is predicted that the new inserts fully meet the practical requirements.
