PROBLEM TO BE SOLVED: To solve such a problem that measurement equipment called an after gauge is frequently provided just behind grinding equipment, when working an inner diameter of a bearing inner ring, and productivity cannot be improved when it requires a long time to perform set-up change of the after gauge even when a set-up change time is shortened by unitization of a main spindle and a grinding wheel spindle.SOLUTION: In the grinding equipment having the after gauge, a set-up change outside the equipment is enabled by unitizing the main spindle and the after gauge respectively. Further, the respective units can also be adjusted outside the grinding equipment by using a machine outer presetter, and the set-up change time of the grinding equipment is shortened thereby. |
