The safe speed of nylon fiber polishing wheel is 1800-2800 rpm/min, and the maximum speed is 3000 rpm/min. The nylon fiber polishing wheel is polished under high-speed rotation, and there is a danger of cracking if it exceeds 3500 rpm/min
According to the abrasive material: it is divided into silicon carbide nylon fiber polishing wheel and corundum nylon fiber polishing wheel. Corundum is usually used for grinding metals, and silicon carbide is used for grinding hard and brittle alloy materials, stone or wood
According to the hardness of the abrasive: generally divided into: 4P, 5P, 7P, 9P, 12P, etc. The larger the number, the harder the polishing wheel and the more durable it is. For polishing stainless steel, iron, alloy products and other hard and brittle materials, 7P, 9P and 12P are generally used. Soft workpieces such as polished copper and antique copper electroplating and drawing generally use 4P and 5P
According to the particle size of the sand in the abrasive: generally divided into: 90, 120, 180, 240, 320 and other particle sizes, the larger the number, the finer the particle size and the finer the polishing. The coarser the particle size, the higher the grinding efficiency, the coarser the grain on the grinding surface, the lower the smoothness, and the more fluffy the corresponding mesh fiber structure
