動きに支障を与えるようになる。The range of cleaning by the grinding fluid supplied between the work material and the grindstone from the surface of the tool itself or another source during grinding is limited to the grinding surface and the tool surface. However, the tool has a mechanism to move the grindstone consisting of a plurality of members inside, and has many concaves, steps, holes, etc. on the inner surface, so that foreign matter accumulates over time and hinders the movement of the tool.

要とする課題を生む。[0008] The tool with respect to the grinding surface is given a fast movement in both the rotation and the up and down directions. However, the movement between the members constituting the tool itself is small, and there is almost no rotation of the grinding fluid to this part. It is difficult for foreign substances to be removed, and gradually penetrates and accumulates in the interior. This deteriorates the movement of the sliding part formed by the sliding hole of the tool body, the adjusting rod and the slider, and requires disassembly and maintenance of the tool.

係する。It is desirable that the tool can be cleaned while it is mounted on the main spindle. However, the type of cleaning depends on the shape of the main spindle and the operating state of the tool, and it is necessary to take into account the cleaning of the tool removed from the main spindle. When the rotating tool is provided with a groove in the wall surface of the sliding hole in the tool body to provide a swirling and downward flow to the cleaning liquid, a high cleaning effect can be obtained. This cleaning function can be used even in a stopped state, but the effect depends on the pressure of the cleaning liquid.

As a straight line or spiral of a book, it is provided between the back end of the sliding hole wall and the open end. When this groove is formed in a spiral shape, the slider mounted on the tool crosses the groove, so that the cleaning liquid overflows from the groove, flows into the space defined by the tool body, the adjusting rod and the slider, and is discharged from the opening end of the tool body such as a slit. It makes it difficult to deposit foreign matter.

率を向上して省力化に貢献した。The grinding tool having a cleaning function according to the present invention has the following effects. The cleaning function built into the tool has made it possible to prevent or eliminate the accumulation of foreign matter regardless of the operating conditions. The cleaning effect on rotating tools was further improved by spiraling the grooves. When the cleaning liquid was a water-soluble cutting liquid, rusting could be prevented by passing an oily solution for a short time after the completion of cleaning. The longer the tool life, the less time required for disassembly and maintenance, and the higher the operating rate, contributing to labor savings.
