ある冷風逃げ通路ｍを通じて大気側へ放出される。On the other hand, the cool air supplied to the cool air supply hole 5 is blown into the inside of the cool air cover 4 so as to come into contact with the surface of the grindstone 3 and open the side open edges 4a1, 4a2 and the peripheral open edge of the cover 4. The air is discharged to the atmosphere through the cool air escape passage m, which is a portion between the surfaces 4b1 and 4b2 and the surface of the grindstone 3, that is, the space where the internal space of the cool air cover 4 is open to the atmosphere.

The area that can be contacted is increased. The fact that the cool air escape passage m is formed relatively narrow acts to restrict the flow velocity of the cool air and to allow the cool air to stay in the cool air cover 4.
Further, the heat insulating material layer 10 prevents the cool air from wastingly absorbing the heat on the atmosphere side through the surface of the cool air cover 4. Therefore,
The cool air in the cool air cover 4 cools the grindstone 3 powerfully and efficiently and evenly.

の雰囲気の温度を上昇させることはないのである。At this time, the fact that the side open edge 4a2 and the peripheral open edge 4b2 of the cool air cover 4 on the side of the grindstone rotating direction are brought close to the surface of the grindstone 3 densely means that the spark passes through the cool air escape passage m. This contributes to preventing the air from flowing into the cold air cover 4. In addition, the fact that the side open edge 4a1 and the peripheral open edge 4b1 project obliquely toward the upper side in the grinding wheel rotation direction makes it possible to improve the flow of the chips colliding with this location in the grinding wheel rotation direction f. Eggplant Therefore, the spark does not enter the cold air cover 4 and the high heat does not increase the temperature of the atmosphere in the cold air cover 4.
【００２２】かくして、砥石３は許容限度を越えて加熱
されることはなく、熱膨張も限られたものとなるため、
工作物を高い寸法精度で加工するものとなる。Thus, the grindstone 3 is not heated beyond the allowable limit, and the thermal expansion is limited.
The workpiece is machined with high dimensional accuracy.

That is, a closed chamber 4r is formed in the thick portion of the cool air cover 4, a cold air supply port 5 for supplying cool air is provided in the closed chamber 4r, and a large number of ventilation holes are provided on the inner wall surface h of the closed chamber 4r.

研削に適したものとなる。According to the second aspect, since the cold air contacts the grindstone for a relatively long time, a large amount of heat is absorbed by a small amount of the cold air. According to the third aspect, the cold air wastes the heat on the atmosphere side. Absorption can be prevented, and according to the fourth aspect, the grinding wheel can be more strongly cooled, which is suitable for grinding in which a large amount of grinding heat is generated.
