[0002] A grinder is a machine tool that uses abrasive tools to grind the surface of a workpiece. Most grinders use high-speed rotating grinding wheels for grinding, while a few use other grinding tools such as oilstones, abrasive belts, and free abrasives for processing, such as honing machines, superfinishing machines, belt grinders, grinders, and polishers.

[0003] Chinese utility model publication number CN 213289825 U discloses a five-axis grinding machine, comprising a base for supporting various processing components in the grinding machine, characterized in that: a processing spindle for cutting a workpiece to be processed is arranged on the side of the base, an output shaft for clamping the workpiece for translation along the x-axis in space is arranged on the upper surface of the base, and the workpiece is rotated around the center line of the workpiece itself through the processing device to cooperate with the processing spindle to cut the workpiece to be processed, and the processing spindle is arranged as a bidirectional rotating cutting knife symmetrical to both sides along its center line;

[0004] The above-mentioned five-axis grinder needs to load and grind workpieces one by one, remove the polished material, and reinstall the next one when grinding workpieces, which is inconvenient to use. For this reason, we provide an automatic loading and unloading CNC tool grinder, which loads materials one by one through the loading rack, and the carrier rack takes the materials one by one and sends them to the rotating rack. As the rotating rack rotates, it cooperates with the grinding head to grind. After grinding, the unloading pusher head pushes out the polished shaft rod, realizing automatic loading and unloading, which is more convenient and effectively compensates for the above-mentioned problems.
