This paper analyzes the existing problems of acting lapping pressure in lapping internal holes of main cylinder of brake-pump with solid abrasives, proposes a new type of solid abrasives supporting method, namely, three supportting points acting lapping pressure method. The method improves pressure distribution between solid abrasives and the surface of the machined workpiece,which is favorable to increase cylindricity of machined hole.Through actual machining process, new method is demonstrated increasing cylindricity accuracy of machined holes of main cylinder significantly.
