我厂加工盘、套类零件时,需要钻孔、扩孔,数量很多。采用麻花钻加工,效率低,劳动强度大。为此,我们参照国外有关资料研制了机夹硬质合金不重磨钻头。通过一年多的生产考验,证明该钻头切削效率高、尺寸稳定、刚性好、寿命长、安全可靠。刀片换位后轴向尺寸不变,特别适用于程控机床上。 I plant plate processing, sets of parts, you need drilling, reaming, a large number. Using twist drill processing, low efficiency, labor-intensive. To this end, we refer to the relevant foreign information developed a folder carbide re-grinding bit. Through more than a year of production test, proved that the drill cutting efficiency, dimensional stability, good rigidity, long life, safe and reliable. Axis after the transposition of the same size, especially for program-controlled machine tools.
