In the grinding machine apparatus, a high-pressure nozzle is provided on the outer periphery of the rotary grindstone at a position on the rotation direction side of the grindstone relative to the grinding point, so as to project a grinding fluid from a direction opposite to the rotation direction of the grindstone, and the high-pressure A grinding machine device characterized in that the high-pressure nozzle is arranged to be inclined downward so that the angle C formed by the high-pressure grinding fluid projected from the nozzle and the grinding wheel surface is an acute angle of 45 degrees or less. (2) The grinding machine device according to claim 1, in which the used grinding fluid is filtered by a grinding fluid filtration element and used for circulation. (3) In the grinding fluid filtration element, a filtration agent made by bending a filter material on a sheet into a corrugated shape is arranged in a cylindrical shape around the outer periphery of a core tube with many through holes on the circumference, and the filtration agent is placed at the upper end of the core tube. A cap with a diameter larger than the outer diameter of the filtration agent is fitted and fixed, and a blind indigo tube with a diameter smaller than the outer diameter of the filtration agent and larger than the outer diameter of the core tube is fixed concentrically with the core tube at the lower end. and the core tube are integrated,
The grinding machine device according to claim 2, which is a grinding fluid filtering element in which openings formed between the corrugated peaks and the core tube are individually closed at the lower end of the filtering agent.
