The invention discloses a high-temperature-
sputtering-preventing protection device for a
numerical control machine tool and a using method of the high-temperature-
sputtering-preventing protection device, and particularly relates to the technical field of
numerical control machine tools. The high-temperature-
sputtering-preventing protection device comprises a
machine tool body, and the right side face of the inner wall of the
machine tool body is fixedly connected with the right side face of a positioning frame; the inner wall of the airtight cylinder is fixedly connected with the outer surface of a first sleeve, and a first guide groove is formed in the left side face of the first sleeve. Through the arrangement of the driving device, the centrifugal cylinder, the
oil pump, the second sleeve and the spraying cylinder, the protection device can recycle cooling liquid while assisting in rapid heat dissipation of a workpiece during workpiece
machining, the situation that the cooling liquid is in a high-temperature state for a long time is reduced, the cooling liquid can be treated in time, and the
cooling efficiency is improved. The cooling liquid is prevented from generating pungent smell due to high-temperature volatilization, the
environmental protection effect of the protection device is improved, meanwhile, the requirement of the protection device for resources is reduced, and compared with an existing protection device, a large amount of cost is saved.
