secondly, centering the workpiece, wherein the electric spindle 43 positioned below the material carrying disc 41 drives the material carrying disc 41 to rotate, and the centering column 423 in the centering assembly 42 arranged below the material carrying disc 41 expands outwards along the kidney-shaped groove 413 on the material carrying disc 41 to abut against the inner ring of the gasket 10, so that centering between the gasket 10 and the material carrying disc 41 is completed;

step three, pressing, namely driving the pressing and adsorbing assembly 32 to descend by the lifting assembly 31 in the hydraulic mechanism 3 above the processing table 1, and pressing the upper end surface of the gasket 10 by the pressing cover 322 in the pressing and adsorbing assembly 32;

step four, adsorption, which is synchronous with the step three, when the gland 322 presses down the gasket 10 tightly, the material loading disc 41 rotates, the centering column 423 on the material loading disc 41 touches the limiting column 324 in the pressing adsorption component 32, then the gland 322 is driven to rotate, in the process that the limiting column 324 touches the centering column 423, the touch switch 325 is turned on, the electromagnet 323 is started, and the gasket 10 is adsorbed;

grinding, namely rotating the electric main shaft 43 to drive the material loading disc 41 to rotate, grinding the upper end surface of the gasket 10 by downward uniform-speed movement through the cooperation of the upper screw rod group 53 and the chain wheel transmission group 54 of the upper grinding mechanism 5 along with the rotation of the rotating main shaft 321, grinding the lower end surface of the gasket 10 by upward uniform-speed movement through the cooperation of the lower screw rod group 63 and the gear transmission group 64 of the lower grinding mechanism 6 along with the rotation of the electric main shaft 43; and

and step six, side grinding, namely, synchronously with the step five, in the process of grinding the upper end surface and the lower end surface of the gasket 10, a side pushing cylinder 74 in the side grinding mechanism 7 drives a side grinding sheet 73 to abut against the side wall of the gasket 10, so that the side wall of the gasket 10 is ground.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
