Polishing machine from manual polishing to automatic polishing machine has undergone a qualitative change, but the process and polishing consumables to get mirror finish effect basically unchanged. How to polish metal to mirror finish? Now, we talk something about the mirror polishing process in polishing casting parts, forgings, elbow welding parts, stamping parts, zinc and gold pieces, and plastic parts.

Manual Polishing Products: Foundry Parts, Forged Parts, Bend Welded Parts, Stamped Parts, Copper Car Parts, zinc and gold pieces, and plastic parts.

1, Casting: 80 # (remove the rough surface) → 180 # (covered with a sand scratch) 400 # → hemp polishing wheel (to remove sand scratch) → cloth polishing wheel (mirror finish effect)

2, forging parts: 180 # (remove the rough surface) → 400 # (covered with a sand scratch) → hemp polishing wheel (to remove sand scratch) → cloth polishing wheel (mirror finish effect)

3, the welding parts: 400 # (to remove the rough surface) → hemp polishing wheel (covered with a sand printing) → cloth polishing wheel (mirror finish effect)

4, stamping parts: 400 # (to remove the rough surface) → 600 # (covered on a sand printing) → cloth polishing wheel (mirror finish effect)

5, copper car parts: 400 # (to remove the rough surface) → hemp polishing wheel (covered with a sand printing) → cloth polishing wheel (mirror finish effect)

6, zinc alloy parts: Sweden 400 # (to remove the mold line, burr and rough surface) →cloth polishing wheel (mirror finish effect)
7, the plastic parts: cloth polishing wheel (to remove the mold line and flash) automatic polishing and process

Automatic polishing products:

1, copper products: manual polishing to removing sand (remove the surface flash and mold line) → manual (automatic) hemp wheel (to remove sand printing) → cloth polishing wheel (mirror finish effect)

2, zinc alloy products: manual polishing to removing sand (to remove the surface flash and mold line) → manual (automatic) hemp wheel (to remove sand printing) → cloth polishing wheel (mirror finish effect)
