2. Description of the Related Art Conventionally, various grindstones according to a work material are often used alone, and a polishing angle at which a work material contacts a grindstone is usually adjusted by a ruler on the grindstone. Ordinary whetstones have low elasticity, and there are rubber whetstones that maintain elasticity,
High-speed polishing that eliminates torque and enhances the degree of polishing is often used.It is susceptible to frictional heat, such as thin objects, blades, resins, and ceramics, and is clogged. Is guided from the tank to the pipe, and the water is directly discharged from the outside to the operating portion of the grindstone at the tip of the cylinder, the degree of retention of the cooling water at the contact surface between the grindstone and the work material is low, and the efficiency such as splashing and escaping around the periphery is low.
If the precision of the processing surface is required, such as the plane of a ruler or plane, spray water and abrasive grains on the surface plate or apply oil to a hard grindstone, attach the support plate to the work material, and slide it manually or mechanically. metal·
Mixing abrasive grains into a cleaner for polishing furniture or the like will leave the adhesive of the abrasive grains on the processed surface. It is extremely difficult to adjust the angle of the work material during the work, especially fine adjustment, and the work is performed such that the quality of the work surface is determined in preparation for the work. Conventionally, the relationship between the liquid tank and the valve is the adjustment, drainage, and suction valve of the cylinder port and the tank for sending and discharging the liquid by the joint pipe.
