车刀使用此种断屑器能提高断屑的可靠性。车削时,切屑受垂直和水平弯曲力的作用而被迅速折断。压花滚轮1偏心装在用弹簧4悬挂的杠杆2上,与辅助滚轮相互接触。排出的切屑碰到滚轮1而向上卷曲,并使滚轮转动。滚轮圆周表面离切屑时近时远,排屑所受阻力也就时大时小,(当向排屑方向的偏心量最大时,阻力最大)。滚轮1和辅助滚轮3不断接
Turning tools use this kind of chip breaker to improve the reliability of chip breaking. During turning, the chip is rapidly broken by the vertical and horizontal bending forces. The embossing roller 1 is eccentrically mounted on a lever 2 suspended by a spring 4 and is in contact with the auxiliary roller. The discharged chips collide with the roller 1 to curl upward and rotate the roller. When the surface of the roller circumference is far away from the chip, the resistance of the chip evacuation is also big and small. (When the eccentricity to the chip evacuation direction is maximum, the resistance is the largest.) Roller 1 and auxiliary roller 3 continue to pick up
