This allows the user to flexibly and accurately adjust the distance between the polishing wheels for different thicknesses of lithium-ion cathode materials, thereby ensuring the accuracy of the polishing thickness of the lithium-ion cathode material and improving the quality and consistency of the product.

[0023] A through groove 17 is provided on one side of the housing 1. A fixed block 5 is rotatably connected to one end of the polishing wheel 13. A side plate 16 is fixedly connected to one side of the housing 1. A threaded rod 15 is threadedly connected to the side plate 16.
