最近,切削加工方面,对工件的加工精度要求越来越高,并且加工材料各种各样,难加工材料逐渐增多。为了适应高性能钻削加工的迫切要求,开发了各种各样的新型钻头。例如经过特殊横刃修磨钻头,改变螺旋角钻头,进行表面处理及硬质合金钻头等均已商品化。OSG公司研究 Recently, the cutting process, the machining accuracy of the workpiece is getting higher and higher, and processing a variety of materials, difficult to process materials gradually increased. In order to meet the urgent requirements of high-performance drilling, a variety of new drill bits have been developed. For example, after grinding with a special chisel edge, changing the auger bit, surface treatment and carbide bits have been commercialized. OSG Research
