Region where blade (11) of the state metal ion in liquid metal polishing fluid (9) carries out high-frequency vibration；Liquid metal is in height
Carrying is blended in the internal abrasive grain of liquid metal polishing fluid (9) and moves together when frequency vibration, and abrasive grain needs to polish to blade (11)
Region efficiently polished.
