[0013] 1. By setting up two grinding machines, positive and negative threaded rods, a first motor, and a slider to work together, the upper and lower surfaces of the shaft can be ground simultaneously. In use, the shaft part is placed in the three-jaw chuck for fixation, so that the shaft is located at the center of the grinding wheels of the two grinding machines. Then, the first motor is controlled to drive the positive and negative threaded rods to rotate. The positive and negative threaded rods drive the two grinding machines to move closer to each other through the slider, thereby grinding both sides of the shaft at the same time. This reduces the number of times the workpiece needs to be adjusted or flipped, reduces working time, and improves production efficiency and capacity.

[0014] 2. By setting up multiple sets of three-jaw chucks, a second motor, a disc, a connecting rod, and a connecting plate to work together, it is possible to conveniently process multiple shaft workpieces. In use, multiple shafts are fixed in the three-jaw chucks respectively. The second motor is controlled to drive the disc. When the disc rotates half a revolution, the disc drives the support plate and the grinding machine to move to the right through the connecting rod. When it rotates half a revolution again, the connecting rod drives the support plate and the grinding machine to move to the left. Similarly, the grinding machine is continuously driven to move back and forth left and right, thereby processing multiple sets of shafts simultaneously, reducing the time for processing individual shafts one by one, improving production efficiency, and facilitating mass production.
