机夹式单刃深孔钻的刀片,一般是不能调整其位置的,刀片装在刀体上后,为了使外刃准确位于导向条所确定的圆周上,必须经过外圆磨削.图示为外排屑可转位式枪钻,该抢钻的特点:①刀片与刀体的接触面有互相咬合的齿纹,调整元头螺钉4,楔块6滑动,楔块的斜面推动刀片沿齿纹做径向移动,使刀片的外刃准确的位于导向条所确定的圆周上.为了调整迅速,可以采用标准样圈等一些简单的量具.②刀片具有对称的切削刃,一组切削刃磨损后,松开压紧螺钉2,将刀片转动180(?)
Machine-mounted single-edged deep-hole drilling blade, the general can not adjust its position, the blade mounted on the knife body, in order to make the outer edge accurately positioned on the circumference of the guide strip must be cylindrical grinding. For the chip removal indexable gun drill, the characteristics of the snatching drill: ① blade and the body contact surface with teeth intermeshing each other, adjust the head screw 4, the wedge 6 slide, wedge ramp along the blade edge The tooth pattern is moved radially so that the outer edge of the blade is exactly located on the circumference defined by the guide strip.In order to adjust quickly, some simple gauges such as a standard sample circle can be used.② The blade has a symmetrical cutting edge, a set of cutting edges After wear, loosen the compression screw 2 and turn the blade 180 (?)
