In order to provide experimental conditions for studying the cutting performance of high speed precision grinding roller, a highspeed roll grinding head of experimental platform is designed in study. The test cycle of experimental platform could be shorten and the cost of the experiment reduced by using a set of simulated load system instead of the grinding workpiece feed system. On this basis, in order to test the performance of the experiment platform for highspeed precision roll grinding head, the static and modal analysis of the overall structure and key components for the experimental platform has been made by using the finite element analysis (FEA) method. The analysis results show that the experiment platform for highspeed precision roll grinding head can meet the performance requirements of strength and stiffness.
