| 摘要 |
The present invention relates to an apparatus for polishing a surface of a metal ingot, which polishes a surface of a hexahedral workpiece. The apparatus (100) for polishing a surface of a metal ingot includes: an upper and lower surface polishing unit (110) to polish upper and lower surfaces of a workpiece; a front and rear surface polishing unit (120) installed vertical to the upper and lower surface polishing unit (110) to polish a front and a rear of the workpiece; and a side surface polishing unit (130) installed vertical to the front and rear surface polishing unit (120) to polish a side surface of the workpiece, wherein each of the upper and lower surface polishing unit (110), the front and rear surface polishing unit (120) and the side surface polishing unit (130) includes a gripper to grip the metal ingot and a polishing pad to polish the metal ingot. The apparatus for polishing a surface of a metal ingot of the present invention automatizes the polishing process for polishing the surface of the hexahedron workpiece constituted by a metal such as a silver ingot thus reducing the work time such that the efficiency and the productivity of the work are substantially improved. |
