[0021] The usage method of the above-mentioned grinding and polishing device for parts in mechanical manufacturing includes the following steps:

[0022] S1. Relevant technicians sequentially pass the first solenoid in the solenoid component through the first side plate and the mounting plate, cause the second solenoid in the solenoid component to pass through the second side plate, and cause the first solenoid and the second solenoid to be preliminarily threadedly connected.

[0023] S2. The starting limit component and the grinding component perform corresponding restrictions on the first screw tube and the second screw tube. At this time, start the transmission component installed on the second side plate to drive the second screw tube to rotate clockwise, and start the grinding component installed on the mounting plate and the transmission component installed on the first side plate to jointly drive the first screw tube to rotate counterclockwise to complete the assembly process of the first screw tube and the second screw tube;
