[0031] Working principle: In the current prior art, when grinding the bushing, the bushing is controlled to rotate to achieve the grinding function. However, when rotating, only one end is fixed and the other end is suspended. When grinding, the force conditions at both ends are inconsistent. When the bushing is long, it is easy to cause the bushing to break, which affects the grinding efficiency to a certain extent and also causes the problem of waste of raw materials. When working, the base 1 supports the workbench 2, and a water cavity is opened inside the workbench 2.

The telescopic rod 4 cooperates with the limiting chuck 5 to fix one end of the bushing, and at the same time, the threaded rod 7 cooperates with the extrusion plate 8 to fix the other end of the bushing, which avoids the bushing from being easily broken when the bushing is long, so that the efficiency of grinding is affected to a certain extent, and it also causes waste of raw materials, thereby improving the efficiency of grinding. At the same time, it can also adapt to bushings of different lengths, and the adaptability is improved to a certain extent. The two ends of the atomizing nozzle 9 and the inner wall of the grinding chamber 3 are fixed. The filter port 10 can pass through the grinding debris and waste water and directly fall into the recovery bucket 12. The connecting rod 11 fixes the recovery bucket 12 to the bottom of the base 1. The support frame 13 is fixed to the top of the workbench 2. The support rod 14 is arranged in the support frame 13. The support leg 15 is fixed to the bottom of the base 1. The lifting platform 16 slides on the support rod 14. The support rod 14 supports and limits the lifting platform 16. The rotating screw 17 rotates to drive the lifting platform 16 to move up and down. The motor 18 is installed on the lifting platform 16.
