一、装配式旋转车刀装配式旋转车刀用来加工不同硬度材料的迥转零件(轴、套筒),或阶级轴。车刀具有刀杆6(图1a、σ),在其内装有转轴4,藉螺母1和7将刀片2夹固在轴4上,且刀片安置在止推轴承3和滚针轴承5的上面。车刀的切削部份可以采用钛钴、钨钴或钛钽钴合金制成的硬质合金刀片,一面具有孔和断屑槽的可换多面硬质合金圆形切削刀片、一面带有后角、孔和断屑槽的可换多面
First, the assembly type rotary turning tool Assembly type turning turning tool for processing different hardness materials to turn parts (shaft, sleeve), or class shaft. The lathing tool has a shank 6 (FIG. 1a, σ), in which a shaft 4 is mounted, the blade 2 is clamped to the shaft 4 by means of nuts 1 and 7 and the blade is mounted on the thrust bearing 3 and the needle bearing 5 . The cutting part of the turning tool may be a cemented carbide insert made of titanium cobalt, tungsten cobalt or titanium tantalum cobalt alloy, a replaceable carbide cemented carbide cutting insert having a hole and a chip breaker on one side and a relief angle , Hole and chip breaker can be changed for more than one
