The 120KW power supply quenches the guide rails 

Machine Tool quenching equipment high frequency requirement, low frequency, quenching the fire hard degree layer will be deeper, the amount of deformation is large, prone to cracking, Machine Tool quenching equipment frequency is too high, quenching the fire hard degree of deformation of the layer will be smaller, However, the sharp angle effect is obvious, and it is easy to melt the sharp corner portion of the guide rail . I for special frequency quenching requirements, development of a heating apparatus for quenching, the apparatus having a frequency suitable quench fire layer depth 2mm , to guide no sharp corners effect, the advantages of a small amount of deformation.
