我国的精密圆柱蜗杆多在配备了手动万能砂轮修整器的螺纹磨床上磨削成形的。这和工艺方法加工出的蜗杆是什么齿形?对此,人们的看法十分不同。有人认为是ZN蜗杆,因为生产图纸上要求ZN;有人认为是ZK蜗杆,因为砂轮近似于盘形锥面砂轮;文献资料普遍认为这种工艺方法加工不出精密的ZN和ZA蜗杆。因此,有必要以S7520w万能螺纹磨床为对象,分析其手动万能砂轮修整器的调整参数对蜗杆齿形的影响。
China’s precision cylindrical worm and more equipped with a manual universal wheel dresser thread grinding on the grinding. What is the shape of the worm that is machined with this method? People have different opinions. Some people think that is the ZN worm, because the production drawings require ZN; some people think that is the ZK worm, because the wheel is similar to the disc-shaped cone wheel; literature generally agreed that this process can not produce sophisticated ZN and ZA worm. Therefore, it is necessary to S7520w universal thread grinder as the object, analysis of its manual universal wheel dresser adjustment parameters on the worm tooth shape.
