今天,可转位的镶硬质合金钻头不但能提供生产上的优势,而且还能加工大范围尺寸的孔,可加工的最小孔径为12.7mm,钻头的长径比为5∶1,其加工速率是前所未有的。
Today, indexable cemented carbide drills not only provide manufacturing advantages, but they also enable the machining of a wide range of holes with a minimum machinable aperture of 12.7 mm and a drill bit with an aspect ratio of 5: 1, machined The rate is unprecedented.
