我厂钻工交道林同志创造了一种新型的综合钻头,这种综合钻头综合了分屑槽钻头和倪志福钻头的优点,改进了钻头的几何形状;从而改善了钻头的切削性能,提高了切削用量、刀具耐用度和生产效率。这种综合钻头头部的几何形状如附图。可以看出,这种钻头同普通钻头比较有下列特点: 1)综合钻头的横刃经过修磨,从横刃的两端磨去1/3。2)头部磨有两个月牙形的分屑槽。3)主切削刃上磨有半月形的分屑槽。
I plant drilling deal Lin comrades created a new type of integrated drill, the integrated drill integrated chip breaker bit and Ni Zifu drill the advantages of improved bit geometry; thus improving the bit of the cutting performance and improve the cutting Dosage, tool durability and productivity. The geometry of this integrated drill head is shown in the attached figure. It can be seen that this drill bit has the following characteristics compared with the ordinary drill bit: 1) The chisel edge of the integrated drill bit is ground to remove 1 / 3.2 from both ends of the chisel edge. The head mill has two crescent-shaped points Chip flute. 3) The main cutting edge grinding half-moon-shaped chip breaker.
