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 neces...
