PURPOSE:To facilitate the production and precision maintenance and reduce the cost as a whole by controlling feeding devices of a spindle stock table, an outside grinding grindstone holder, and an inside gripping grindstone holder respectively with a numerically controlled device via numerical commands. CONSTITUTION:A spindle stock 4, an outside grinding grindstone holder 13, and an inside grinding grindstone holder 9 are fed by the one-direction one-slide system respectively, and the whole is formed into the three-axis constitution. Thereby, the structure of the device can be simplified, and the production and the precision maintenance of the device can be facilitated. In addition, the outside grinding work and the inside grinding work can be performed without changing the arrangement, thus the work efficiency is improved. Accordingly, the cost is reduced as a whole. |
