  现在在机械行业做天博体育,可真是越来越难、公差要求越来越严、表面粗糙度的要求也越来越高、如果加工出来的天博体育精度受损,那么这个天博体育也就基本报废了……有些震刀,一般人只见过一次,因为见一次刀就被毁了,其实,除了数控车床的刚性,还有其它一些因素也影响车床震刀会不会产生。

  1、三要素互相调和

  2、优先选择短刀具

  3、更现代化的加工路径

  (5)改变刀具的外型与进角,刀具鼻端半径(Nose Radius)越小越好,以降低切削阻力。 侧倾角(Sick Rake Angle) 必须取正值,以使切削方向更近垂直。后倾角(Back Rake Augle) 最好为正值,惟甚去屑切屑能力相对变差,因此一般可选 用槽刑刀以使倾角变为负值,但仍保有正值的切削效果。
