AI Technical Summary

Problems solved by technology

[0004] At present, the vast majority of domestic CNC turntable manufacturers can only measure the static parameters of the CNC turntable when testing the key performance parameters of the CNC turntable, but cannot effectively measure the most critical dynamic parameters for evaluating the performance of the CNC turntable, so until now A set of standards for testing and evaluating the performance of CNC turntables has not yet been established

[0005] Therefore, in view of the shortcomings of the current detection process, it is necessary to conduct research to provide a solution to solve the defects in the existing detection process and avoid the inability to detect the various performance parameters of the CNC turntable under the action of dynamic load. The invented NC turntable test bench load control system for simulating working conditions can be used to accurately and truly simulate the static load and dynamic load borne by the NC turntable in the actual working conditions in the test environment, and the key to conveniently detect the NC turntable Performance
