In this paper, the problem of the aperture stability of large spherical optical parts during high-speed grinding is theoretically analyzed, and the distribution of the relative linear velocity and the distribution of pressure in spherical grinding are calculated. Combined with the processing characteristics of large spherical optical parts, the design principle and method of large spherical high-speed fine grinding disc are proposed. And in the first design and manufacture of QPM220 spherical high-speed refiner, the experimental assessment confirmed the correctness of the theoretical analysis and the feasibility of the design method of the spherical high-speed fine grinding disc. Also on the machine parameters of how the stability of the aperture and its rate of change as well as the impact on the amount of glass to wear out the useful data and its laws.
