Japanese Patent JP2023170074

A

To provide a vertical rotation type ELID processing device and the like which can properly perform dressing of a blade with an electrolyte even in a case where the rotational speed of the blade is fast.SOLUTION: An ELID processing device comprises: a blade which vertically rotates; a nozzle part which discharges an electrolyte toward the vicinity of the apex position of the blade; an electrode part which is provided on the rotation forward direction side of the blade from the vicinity of the apex position; a power supply part which forms an electrical field between the electrode part and the blade; and a drive part which rotationally drives the blade. The height t from a rotation center horizontal surface being a horizontal surface passing through the rotation center of the blade at the opening center of a nozzle opening from which the nozzle part discharges the electrolyte is 0.036≤(r-t)/r≤0.092 when the radius of the blade is r.SELECTED DRAWING: Figure 1
