维修针阀体座面电火花机床需要一小小蜗轮,Z轮=28,m=1,d分=28,与蜗杆啮合的中心距是18.5mm,蜗杆头数 Z杆=1。我厂没有合适的滚齿机,若在铁床上用飞刀加工,蜗杆直径只有11mm,刚性很差,无法吃刀。我们制作了如图所示的简单装置,把车床小拖板以上部分拆去,将该装置安装在中拖板上, Needle body seat surface repair EDM machine needs a small worm wheel, Z wheel = 28, m = 1, d points = 28, and the worm gear center distance is 18.5mm, the number of worm Z rod = 1. I plant does not have a suitable hobbing machine, if the iron bed with a flying knife processing, worm diameter of only 11mm, poor rigidity, can not eat knife. We made a simple device as shown in the figure, removed the above part of the lathe pallet, mounted the pallet on the pallet,
