硬质合金滚刀的出现突破了长期以来磨齿是硬齿面齿形精加工惟一有效的工艺方法。它具有不需专用设备,效率高、成本低等一系列优点。它的出现是硬齿制造技术中的一项重大革新。我们在对硬齿面齿轮精加工方面,经过摸索研究,实际使用,以刮代磨,取得了成效。提高了对硬齿面刮削加工 The emergence of carbide hob has broken through the long-term grinding is the only effective method of the hardened tooth profile finishing. It has no need for special equipment, high efficiency, low cost and a series of advantages. Its emergence is a major innovation in hard tooth manufacturing technology. We are hard on the gear surface finishing, after groping research, the actual use of scraping on behalf of the mill, and achieved results. Improve the hard tooth surface scraping process
