下面所说的车刀,是应用机械立法迅速而牢靠地把硬质合金刀片夹紧在车刀上。它在构造上,是利用着在切削过程中作用于切削锋刃垂直面上的切屑力的。为了夹得牢靠,硬质合金刀片要安置得不致被切屑力所打落,或者被挤出於刀桿的槽座之外。经验说明:用机械固定法的车刀与焊接法的 The turning tool mentioned below is the application of mechanical legislation to quickly and securely clamp a carbide blade to a turning tool. It is constructed in such a way that it utilizes the force of the chips acting on the vertical plane of the cutting edge during the cutting process. In order to clamp the solid carbide inserts to be placed so as not to be struck by the force of the chips or be squeezed out of the seat of the shank. Experience shows: the use of mechanical fixed method of turning and welding method
