Aluminum Tube Polishing Fire Problem: A Case Study

Aluminum was a type of hard and soft material, because of its high toughness, and it was easy to generate grinding heat, so polishing was relatively difficult because of polish fire. Aluminum has been used as a processing material due to its excellent properties such as lightness, corrosion resistance, non-magnetism, alloy strength, electrical conductivity, weight, and heat dissipation. However, some problems arose when grinding aluminum tubes. Thereby, two grinding methods have been performed to reduce polish fire. An elastic polishing wheel with special heat dissipation was used. There were many grinding wheels on the market, which were adjusted according to the material. For example, the finer-grained elastic polishing wheel was used because of the elastic grinding wheel being elastic, but such wheel was afraid of vibration during high-precision polishing. Therefore, these two grinding methods have shown that the polish fire was reduced and lead to the problem of good processing efficiency with the best solution.
