[0002] Slide grinding fixtures typically include a positioning mechanism, which is movably mounted on a CNC machine tool and its rotation is controlled by the CNC machine tool's system settings. The positioning mechanism's design allows the slide to easily change grinding angles, avoiding the hassle of repeated installation and disassembly, and also reducing uneven grinding thickness caused by installation position deviations. A cylinder is mounted on the base, located on the horizontal extension line of the positioning mechanism and perpendicular to it. When the slide is fixed to the positioning mechanism, the cylinder presses against the slide from below, providing radial support force and ensuring a more stable position of the slide during grinding.
