车床刀具左钻和麻花钻有何不同为什么要用左钻

[2020-04-16 09:32:22]

没有接触过车床刀具左钻的人肯定是不了解左钻的，在钻孔领域中也不是所有人都会接触到左钻，左钻的主要由来是因为自动车床这款设备，自动车床默认为左旋左向旋转，而麻花钻都是适用于正向右旋的设备，所以因为设备不同才会有左钻的出现。

车床刀具左钻

车床刀具左钻和麻花钻不同之处小编有讲过很多次，螺旋槽是最好的观察点，一个是左一个是右，其次不同之处有标准的规格刃长总长设定不同，麻花钻需要那么长，但是左钻并不需要，品质的定位与麻花钻也有所不同，左钻基本是中高端品质，普通的材质肯本无法满足车床刀具左钻的加工，工艺的设定基本也是根据加工金属钢材来设定的。

车床刀具左钻

说到为什么要用车床刀具左钻，主要的原因就是自动车床这款设备了，自动车床实际上也可以用右钻麻花钻，但是毕竟复杂，从事自动车床多年的师傅以及技术人员都以及习惯反向的主轴，如何调整到右钻会让很多自动车床工厂的操作人员感觉得不顺手，不舒服，所以大多数的自动车床对于钻孔首选的依旧是车床刀具左钻。
