Grinding and Polishing Repair Technology and Experimental Research on Surface Defects of Flywheel Disc Semi-Finished Products

Abstract The flywheel disc is an important engine component that widely used in industries such as automobiles, ships, and energy storage. In this paper, single-factor experiment, orthogonal experiment are to explore the influence of abrasive particle size, grinding speed, pressure, time on surface roughness material removal rate semi-finished products (cold-rolled steel). results show optimal combination parameters for defect repair process is: size W20, speed 40 r/min, pressure 3 psi, min, average 342nm. repaired product has great quality meets requirements factory repair.
