Influence of grinding wheel speed on quality in thermal spray coating grinding

       Tests show that if the speed of the grinding wheel is too low, the wear of the grinding wheel will increase, and the roughness of the machined surface will be deteriorated. However, if the speed of the grinding wheel is too high, the wear of the grinding wheel will also increase, and the improvement of the roughness of the machined surface is not obvious. Therefore, the grinding wheel speed has a reasonable value under certain processing conditions. Generally, green silicon carbide grinding wheel v=20m/s~25m/s; synthetic diamond grinding wheel v=15m/s~25m/s; cubic boron grinding wheel v=25m/s~35m/s.



    

     As the axial feed increases, the productivity increases, but the wear of the grinding wheel also increases. The roughness of the machined surface increases. Generally, the internal and external cylindrical grinding fa= 0.5m/min~1m/min; the plane grinding fa=10m /min~15m/min.

     

     If the workpiece speed is too high, it is easy to generate vibration. General workpiece speed vw=10m/min~20m/min.
