[0002] A CNC grinder is a machine tool that uses computer numerical control technology (CNC) to control the grinding process. It uses pre-written program instructions to control the grinder for automated processing, achieving high-precision and high-efficiency workpiece grinding. CNC grinders usually cover functions such as grinding, polishing, etc.

[0003] When the workpiece is transported into the grinder for processing, it takes a certain amount of time to grind the workpiece in the grinder, and a certain amount of workpiece debris will be generated during grinding. When multiple workpieces are simultaneously ground in the grinder, friction and collision may occur between the workpieces, thereby causing certain damage to the workpiece as a whole. When people adjust the feed spacing of the workpieces, multiple operations increase people's labor intensity and reduce the overall feeding efficiency of the workpiece.

[0004] With respect to the above-mentioned related technologies, the inventor believes that there is a defect that it is inconvenient to control the feeding spacing when feeding the workpiece before grinding. Therefore, a positioning and pushing device for a CNC grinder is proposed to solve the above-mentioned problem. Utility Model Content
