a) Even tearing or braking abrasive belt will not hurt operators.
b) Easy to be changed abrasive belt, during operation without any concern about belt elongation.
c) High/low speed design. High speed for polishing large cutting surfaces. Low speed for polishing easy cutting work pieces.
d) Four simulation rollers that are changeable for fast and convenient operation.
