A method for processing a seal surface with a high-precision grinder according to any one of claims 1 to 5, characterized in that: The following steps are involved: S1) Fixing the workpiece: fit the upper surface of the seal to the lower surface of the fixed disk, and place the assembly on the grinding disk so that the lower surface of the seal contacts the diamond particles on the grinding disk, and the fixing groove on the upper surface of the fixed disk corresponds to the pressure head. The PLC control box controls the extension and retraction of the cylinder through the air pump. The extension end of the cylinder pushes the connecting column, and then the pressure head presses the fixed disk tightly. S2) Start the equipment: start the motor, light bulb, exhaust fan and water pump through the PLC control box, the output shaft of the motor drives the second pulley to rotate, the second pulley drives the first pulley to rotate through the belt, and then the first pulley drives the rotating shaft to rotate, the rotating shaft drives the grinding disc to work, the water pump draws water from the water tank through the water pipe and discharges it through the water outlet, the exhaust fan discharges the heat of the protective box to cool the equipment; S3) grinding: the PLC control box adjusts the rotation speed of the motor through the frequency converter, and then the grinding speed can be adjusted. The grinding time is pre-set through the PLC control box. The grinding disc grinds the surface of the seal with diamond particles. The grinding disc drives the seal to rotate. The water outlet cools the diamond particles and the grinding surface of the seal through water, and at the same time, the ground powder is washed off from the grinding disc, thereby ensuring the quality of grinding; S4) Taking out the workpiece: When the set grinding time is reached, the cylinder is retracted through the PLC control box, and the telescopic end of the cylinder drives the pressure head to retract, and the ground seal is taken out; S5) Cleaning: The air pump pressurizes the pressure tank through the air pipe, and the pressurized water is sprayed out through the nozzle through the water pipe. The nozzle cleans the grinding chamber, and the opening and closing of the solenoid valve is controlled by the PLC control box, thereby controlling the nozzle.
