Description of the Related Art In the process of processing a magnetic head, a semiconductor device, etc., when performing so-called wet grinding in which cutting and grooving of various materials such as head materials and semiconductor wafers are soaked in a grinding liquid, so-called wet grinding The processing equipment for the purpose of improvement has advanced in performance, and the rotation of the grindstone has been accelerated.

供給する工夫が必要となっている。Along with this high-speed rotation, the air flow around the grindstone becomes extremely fast, which makes it difficult to supply the grinding fluid to the working point. For example, there is a problem that clogging occurs due to lack of grinding liquid, the cutting line meanders and cannot be cut linearly, or the grindstone wears very quickly. For this reason, it is necessary to devise a reliable supply of the grinding fluid so as to meet the improvement of the processing device and the performance of the grindstone.

A disk-shaped grindstone 1 is fixed on both sides thereof by flanges 2 (one side surface is shown in FIG. 6), and is rotated at a high speed as indicated by an arrow c with a grindstone rotating shaft 4 as a rotation axis. At this time, the grinding liquid is supplied from the peripheral portion of the grindstone 1 to the processing point for the purpose of cooling the grindstone 1 and the workpiece, that is, the so-called work, and further removing the processing scraps. Reference numeral 5 shows the flow of the grinding liquid.

0 m / s or less, that is, when a grindstone with a diameter of 100 mmφ is used, when high speed rotation is performed at a rotation speed of about 5000 rpm to 20000 rpm, a flow of air is generated in the peripheral portion of the grindstone 1 as indicated by an arrow a, and the grinding fluid is processed. The supply to the point is hindered. The shortage of the grinding fluid accelerates the wear of the grindstone 1 and causes heating, which causes an increase in grinding resistance and a reduction in processing accuracy.

Particularly in the process of forming the track width regulation groove, it is desired to maintain the shape of the grindstone for a long time. Further, in the manufacture of a thin film magnetic head for a hard disk, it is required that the cut surface of the ceramic Al 2 O 3 —TiC, which is a difficult-to-cut material, be precisely flat. Further, for example, in the manufacturing process of semiconductor devices, it is required to increase the rotational speed of the grindstone in order to shorten the processing time in the wafer cutting process.

However, this method requires expansion of equipment. Further, the grinding liquid may collide with the work unnecessarily at a high speed, and the work may come off, or the work may be damaged.

Therefore, it is technically difficult to realize. In addition, the grinding liquid may be unnecessarily attached to the work and may be contaminated.

Taking into account the depth of 0.05-0.1
It is desirable to set it to about mm. In addition, since the efficiency of negative pressure is reduced when the depth of the recess 13 is small as described above, the number of recessed recesses 13 or the number of recesses when the recesses are provided is the same as when the uneven portion is formed on the grindstone flange. It is desirable to make it larger than.
