The invention relates to an inner-cooling bonded abrasive grinding disc, belongs to the field of bonded abrasive grinding and processing, and particularly relates to an inner-cooling bonded abrasive grinding disc used for single-side grinding or double-side grinding materials of silicon, sapphire, ceramic, glass and the like. Cooling liquid circulating channels are arranged inside the grinding disc. The grinding disc comprises multi-hole grinding blocks, a base plate and a spreader plate. The multi-hole grinding blocks are provided with abrasives, the base plate is provided with a plurality of hole channels, and a central hole and a groove are reserved on the spreader plate. Each multi-hole grinding block is fixed at one end of the hole channel of the base plate through bonding agents, and the large air holes in the multi-hole grinding blocks are communicated with one another. The cooling liquid circulating channels are formed by the central hole of the spreader plate, the grooves of the spreader plate, the radial grooves of the spreader plate, the hole channels of the base plate and the large air holes of the multi-hole grinding blocks. Since the grinding disc is provided with inner-cooling circulating channels, cooling effect can be improved, the grinding disc and workpieces can be prevented from being burnt off, size accuracy of the processing workpiece is high, and surface roughness is good.
