Due to objective technical reasons, most of the domestic and foreign countries use traditional knife bowls for turning. In the process of processing it, 4.5 inches grinding wheel drives the quenched 45th steel thin-walled knife bowl to rotate at a higher linear velocity (300-400 m/min), and carries the cutter to remove the excess amount of the grinding wheel.
Due to the high-speed rotation of the processed 4.5 inches grinding wheel and the knife bowl, the dust and noise in the processing are large, the cutting depth and the feed amount are small, so the processing efficiency is low and the comprehensive cost is high, and the operator is labor intensive.
If a large-grain diamond cutter is used, it is expensive, and because the diamond has low bending strength, it is easily damaged during cutting, and the cutting depth and the feed amount when cutting the 4.5 inches grinding wheel are small, and it is generally used only in finishing.
