插床上加工钢件,如果采用整体插刀杆,在返回行程时,插刀的后面将在工件已加工表面上硬擦过去,造成插刀后面急剧磨损,降低刀具耐用度,增加了刃磨工作量:同时影响已加工表面的尺寸精度和光洁度。针对上述问题,我们设计了如附图所示的活动插刀杆。经长期实践证明,效果良好。 Slotted steel processing, if the overall insert rod, the return stroke, the back of the knife will be in the workpiece has been hard-scratched the surface of the past, resulting in sharp knife behind the sharp wear and tear, reducing tool durability, increased sharpening work Amount: Also affects the dimensional accuracy and finish of the machined surface. In response to the above problems, we designed the movable insert rod as shown in the attached drawings. After long-term practice proved effective.
