特殊双线内螺纹在数控车床上加工时,会产生粗精车螺纹刀不吻合、双线内螺纹在两开合零件块分布不对称、2条不同形状螺旋线起刀点与退刀点距端面距离不相等、内螺纹底孔面不光洁及有棱角问题,为解决生产实际难题,从数控车削加工工艺制定、夹具调节、加工程序编写、刀补修改方法 4方面进行详细阐述,来保证包含该特殊双线内螺纹的模块零件要求。
Special two-wire internal thread on the CNC lathe processing, will produce crude car thread does not match, two-line internal thread opening and closing parts block distribution asymmetry, two different shapes spiral starting point and retracting pitch End face distance is not equal to the end of the female hole is not smooth and angular problems, in order to solve the practical production problems, CNC lathe from the development process, fixture adjustment, the preparation of the processing procedures, knife repair methods to amend four detailed description to ensure that contains The special two-wire female threaded module parts requirements.
