随着电机、电器、仪器仪表等行业的发展,对冷冲模的使用,在数量和质量上的要求越来越高,广泛采用硬质合金模具代替一般钢冲模;特别是电火花加工的发展,解决了凹模型腔的加工问题,若硬质合金模具的平面磨削仍采用一般机械磨削,就不能适应生产需要。近年来我厂吸取电解磨削新工艺,应用以电化学溶解为主,机械磨削为辅,通过一年的试验研究,成功地解决了硬质合金平面磨削加工。现介绍于下。
With the development of electrical, electrical appliances, instrumentation and other industries, the use of cold stamping dies is increasingly demanding both in quantity and in quality. Carbide dies are widely used instead of ordinary steel dies. In particular, the development of EDM, Solve the cavity of the cavity processing problems, if the plane of the carbide grinding machine is still using general mechanical grinding, it can not meet the production needs. In recent years, I learned a new electrolytic grinding process, the application of electrochemical dissolution-based, mechanical grinding, supplemented by one year of experimental study, the successful solution to the carbide surface grinding. Now introduced in the next.
