Description of the Related Art A grindstone for dry-processing a ceramic compact as described above is apt to be clogged with a ceramic powder, and particularly a β-alumina tube containing Na and having a hygroscopic property tends to have this tendency. Is remarkable. Therefore, conventionally, the whetstone is dressed with a WA stick or the like every time the grinding amount reaches about 150 cm 3 , but the dressing time occupies a large proportion of the time required for the process and has a drawback of low productivity. Further, since dressing is frequently performed with a hard dresser, there is a problem that the life of the grindstone is short due to abrasion of the abrasive grains, change in the shape of the grindstone, and the like.

The pressure of the air blow is 2 kgf / cm 2 or more, more preferably 4 kgf / cm 2 or more. 1 and 2, the nozzle 2 having the ejection holes formed at intervals of about 5 to 10 mm is used.
You may use the nozzle 2 which has a slit of about 0.5-2 mm. Further, as shown in FIG. 2, the blowing angle of the air blow with respect to the surface of the grindstone is 90 ° at its best, but an appropriate angle may be set within the range of 30 to 120 °. In this case, the blowing angle of the air blow is measured from the rotational direction of the tangential line of the grindstone outer periphery as shown in FIG.

-It is not preferable because it adheres to the alumina tube and reduces the quality. Further, the brush of synthetic resin is not preferable because it is melted by frictional heat and adheres to the surface of the grindstone. Brushing may be performed intermittently for each cycle. If brushing is constantly performed during processing, the brush may wear and the brush replacement time in the process required time may become long.
