【摘要】 采用成形陶瓷刀具车削GCr15钢制淬硬套圈沟道,以代替现行粗磨工序。实验表明,车削后的沟道粗糙度、烧伤和变质层等均可达到粗磨的要求;实验条件下的内(外)圈沟道对内(外)径的厚度变动量和单一径向平面内的沟道直径变动量较大,车削工艺的优点在于提高加工效率和减少砂轮消耗。更多还原

【Abstract】 Turning hardened GCrl5 steel bearing ring raceway with ceramic form cutting tool is adopted instead of rough grinding in operation. Practice shows: 1. Requirements of roughness, burn and surface layer quality for rough grinding can be reached. 2 . In experimental condition, the inner(outer) ring raceway to bore (outside sarface ) thickness variation and the raceway diameter variation in a single radial plane of bearing ring are relatively poor, but the process efficiency is higher and the consumption of grinding wheel is reduced.更多还原
