Filed: 2020-03-19
Abstract: To provide a grinding liquid supply device in which the clogging of a whetstone is improved in the processing of a metal product by whetstone grinding, the continuous processing continuation becomes possible even if a whetstone cut amount is greatly increased more than before, and thereby the efficiency of the grinding is improved.SOLUTION: A water-based grinding liquid CL is brought into contact with the surface of processing medium particles to make cavitation processing, and then is supplied to a grinding device 100. An insulating ceramic for making the processing medium particles is porous in which the porosity is 10% or more and 60% or less. Also, the one with the apparent specific gravity of 1.0 or more is employed, and thereby comes in contact with the water-based grinding liquid CL at a stable flow rate without floating in the casing. Thereby, the cavitation where the dissolved air in the water-based grinding liquid CL is decompressed and precipitated is generated on the surface of the processing medium particles, and the permeability to the whetstone 101 surface of the water-based grinding liquid CL is improved. As a result, the clogging of the whetstone 101 is improved dramatically by the simple liquid processing, and therefore the continuous processing continuation becomes possible even if a whetstone cut amount is greatly increased more than before.SELECTED DRAWING: Figure 1
