Background
The grinding tool of cup wheel class, the working face is the ring end face work ring, and during the course of working, the work piece can cover the whole port of emery wheel, perhaps cover the partial port of each different positions of emery wheel, and at this moment, cooling water will be difficult to apply to the emery wheel inner chamber from emery wheel port department, and simple mode is applied in emery wheel external diameter incision department, constitutes external cooling mode, but because the effect of centrifugal force, cooling water is difficult to act on the internal diameter from the external diameter, consequently the cooling effect is restricted, especially the portion that the emery wheel leans on the internal diameter, and the effect is usually bad. During high-speed rotation processing, the inner surface, the outer surface and the end surface of the grinding wheel form an air flow barrier, and the external cooling effect of the grinding wheel is greatly affected. In order to improve this situation, the technical solutions adopted at present are:
in the first mode, as shown in fig. 1-2, a plurality of large holes are formed on the end face of the substrate, namely, the water through holes 501 in fig. 1 are formed, cooling water is injected into the inner cavity of the grinding wheel through the large holes, the mode can solve the problem that the cooling water enters under the condition of low rotation speed, the arrow in fig. 1 shows the flowing direction of the water, the water enters into the inner cavity of the grinding wheel, and a part of the cooling water contacted with the grinding wheel is subjected to the centrifugal force effect, so that the cooling is carried out along the water tank or the grinding surface from the inner diameter to the outer diameter.
