硬质合金滚刀发展概况早在三十年代,就有人提出用硬质合金齿轮滚刀提高滚齿速度,并陆续在非金属齿轮和有色金属齿轮加工中得到应用。五十年代末,瑞士研制成功小模数齿轮的整体硬质合金滚刀,并在小模数钢齿轮的实际加工中取得了好的经济效果。但世界上不少国家在用硬质合金齿轮滚刀滚切模数大于1.5毫米的钢齿轮的研究试验中,无法克服滚刀崩刃的难题,而停止了此项研究试验。 Carbide Hob Development Overview As early as the 1930s, it was proposed to use carbide hob hob to improve hobbing speed, and one after another in the non-metallic gears and non-ferrous metal gear processing applications. The late fifties, Switzerland successfully developed a small modulus gear solid carbide hob, and in the actual processing of small modulus steel gear achieved good economic results. However, many countries in the world in the use of carbide hob hob cutting modulus greater than 1.5 mm steel gear research test, the hob can not overcome the chipping problem, and stop the research test.
