Friction and Flow Behavior of Ceramics in Ring-Compression Test

Float polishing is one of the advanced ultra-smooth surface polishing techniques. Mechanical structure and polishing principle of float polishing are introduced. Polishing experiment about polishing ultra-smooth surface of GCr15 rectangular workpiece is performed by the CJY500 ultra-precision polishing machine, experimental results show that float polishing should be achieved metal nanometer level surface without degenerating layer. The application scope of float polishing is extended, the application has significant reference value for polishing ultra-smooth surface of metal workpiece.
