在车刀上附加断屑器(苏联专利号1242308)能提高车刀破断切屑的可靠性。如图所示,滚压滚子1偏心地安装在杠杆2上,杠杆悬在弹性件4上,滚子1又与滚子3相接触。被车下来的切屑支靠在滚压滚子1上,方向向上,导致滚子1旋转。由于滚子1是偏心安装,它时而移近切屑,时而离开切屑。又由于它与滚子3摩擦接触,导致它与杠杆2一起振动,增大切屑破断的力,保证切屑在一定长度上破断。根据切削工况,滚子1和工件表面的距离
The addition of a chip breaker to the turning tool (Soviet Patent No. 1242308) increases the reliability of the turning tool to break the chip. As shown, the rolling roller 1 is eccentrically mounted on a lever 2 which is suspended on the elastic member 4 and which in turn is in contact with the roller 3. The scraped chips that come down by the car rest against the roller 1 and the direction is upwards, causing the roller 1 to rotate. Since roller 1 is eccentrically mounted, it sometimes moves closer to the chip and sometimes leaves the chip. And because it is in frictional contact with the roller 3, causing it to vibrate with the lever 2, increasing the force of chip breaking, to ensure that the chip breaks to a certain length. According to the cutting conditions, roller 1 and the workpiece surface distance
