Different materials of plasma polishing machine, it needs to adjust the parameters are not the same. Small plasma polishing machine can polish stainless steel and titanium metal, then their parameters are different? If you want to polish stainless steel, it is generally polished with 300 volts. If you want the details of the plasma polishing to be better, change its voltage. If its details require only the outer surface to be polished, 300 volts is sufficient. Then is our polishing time to determine the polishing effect is good or bad. The longer the polishing time, the better the quality of the product surface, the more shiny. If you want to polish titanium metal, the configuration of the plasma polishing machine is different, it will have what we call the pH of this piece, pH is specifically to do our titanium of this piece, it is the normal value of the pH probe, it is a different titanium material, and then there is a different pH to deal with it, you can do a good job of the product.
