车床刀具左钻是一种什么样的钻头

[2020-04-15 09:50:17]

说起钻孔加工相信多人第一个想到的钻头肯定是麻花钻，但是在车床的钻孔领域中有一种车床刀具钻头叫做“左钻”，左钻主要用于自动车床以及一些可以反转左旋的设备，那么左钻是一种什么样的钻头呢？

车床刀具

从外观上来讲，左钻和标准的直柄麻花钻并没有太大的区别，唯一可以肉眼观察出来的，第一点是螺旋槽的旋转方向不同，第二是相同的规格下左钻和麻花钻的总长刃长会有所不同的，第三如果仔细的观察会发现标准的车床刀具左钻和标准的麻花钻螺旋槽以及钻尖的工艺处理也会有所不同。

车床刀具左钻

因为适用的领域不同，麻花钻适用于很多种钻孔设备，但是左钻基本上只适用于自动车床以及一些冷门的可以反转的设备，左钻和麻花钻并没有质量的可比性，车床刀具左钻主要针对的材质都是一些铜铁铝不锈钢等钢材，所以在质量上的设定定位都是中高端的，而麻花钻适用领域及广，品质的设定也是有高有低，不了解左钻请不要盲目的选择，宝佳联昕切削刀具十余年专注服务于车床工厂，专注左钻研发生产定制。
