技术领域technical field

The overall rigidity of fixtures and tools changes, and various workpiece quality problems caused by resonance will occur when machining workpieces, such as cylinder bore processing chatter marks, surface chatter marks, thrust surface chatter marks, or cylinder bores processed into ellipses, etc. A series of quality problems. When there is a quality problem, even if the electric spindle itself has good detection parameters, it has to be replaced with a new spindle to change the cooperation with the tool and prevent resonance problems. This greatly reduces the service life of the electric spindle. Therefore, how to prevent the electric spindle from resonating is a technical problem to be solved urgently by those skilled in the art.
