Grinding and polishing equipment and technology for wood board processing

The invention belongs to the technical field of wood board processing, and discloses grinding and polishing equipment and process for wood board processing, the grinding and polishing equipment comprises a base, supporting plates are fixedly mounted on the top surface of the base, first electric push rods are fixedly mounted on the side surfaces of the supporting plates, and the number of the first electric push rods and the number of the supporting plates are both two. Interference on follow-up grinding and polishing is relieved after convenient positioning is completed, meanwhile, a negative pressure mechanism is used for sucking air in a side clamping plate, when the side clamping plate clamps a wood board and seals a side hole in the corresponding side, the air pressure in the side clamping plate is reduced under continuous suction, and therefore the wood board is further adsorbed through the low-pressure effect; and therefore, enhanced adsorption fixation of the wood board is completed, clamping fixation
