The rotation of the third drive motor 63 drives the grinding discs 64 to rotate, and the grinding discs 64 grind the inner hole of the hydraulic cylinder. The extension and retraction of the electric telescopic cylinder 7 pushes the turntable 61 to slide along the slide, thereby completing the grinding of each position of the inner hole of the hydraulic cylinder by the grinding discs 64.

The support roller 10 on the third support 9 supports the rolling of the hydraulic cylinder body. The chuck 3 clamps one end of the hydraulic cylinder body. The first drive motor 4 rotates to drive the chuck 3 to rotate, thereby causing the hydraulic cylinder body to rotate. Second, the third drive motor 63 rotates to drive the grinding disc 64 to rotate. The grinding disc 64 grinds the inner hole of the hydraulic cylinder body. The extension and retraction of the electric telescopic cylinder 7 pushes the turntable 61 to slide along the slide, thereby completing the grinding of various positions of the inner hole of the hydraulic cylinder body by the grinding disc 64.
