The shortcomings of the traditional technology of the grinding wheel

  
  With the continuous advancement of technology, various production and processing technologies are constantly improving. Traditional technologies are constantly being abandoned. Of course, the shortcomings of traditional technology are abandoned. Let us talk about the shortcomings of traditional techniques in terms of the [u]depressed grinding disc for metal[/u]:
 
    After the grinding wheel is subjected to calcination and solidification, the size, shape and positional accuracy of each surface are not up to the technical requirements of use and must be turned, ground and ground. The unit using the depressed grinding disc for metal is also indispensable for the production and the specifications of the grinding wheel, and it must be turned. Due to objective technical reasons, most of the domestic and foreign countries use traditional knife bowls for turning.
 
   In the process of processing it, the depressed grinding disc for metal 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 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 depressed grinding disc for metal are small, and it is generally used only in finishing.
