元宝螺帽(Wing Nuts或Thumb Nuts)是常用机件之一,它的加工虽然没有什么困难和特别精密的地方,但是由于它的形状不规则的限制,要在机床上进行大量生产倒是比较困难的。我们曾经研究出一种在车床上加工的方法和卡具,生产效率很高,平均每分钟完成4-6个,而质量可保持百分之百,操作 Wing Nuts or Thumb Nuts is one of the most commonly used parts. Although its machining is difficult and precise, due to its irregular shape, it is more difficult to mass produce on a machine tool of. We have worked out a method and tool for machining on a lathe, with high production efficiency, with an average of 4-6 pieces per minute, while the quality can be kept at 100%. The operation
