Description

technical field [0001] The invention relates to a grinding and polishing machine equipment, in particular to an acoustic levitation polishing equipment for nanomechanical characterization samples. Background technique [0002] Nanoindentation system technology is gradually becoming one of the most important testing methods in the field of nanomechanical characterization. It can accurately complete indentation experiments with a range of tens of nanometers, forming a nanoindentation measurement technology. However, the sample preparation method for nanomechanical characterization is a recognized technical problem in this field that needs to be solved urgently. The more processing methods used today are focused ion beam processing, elastic emission processing, fluid vibration polishing technology, etc. Although these methods have achieved certain results in the preparation of samples for nanomechanical characterization, there are still many problems. Such as focused ion beam ...
