Effect of corrosion on sawing stability of diamond circular saw blade
When the rusted diamond circular saw blade works,there will be some problems such as reduced sawing stability.In response to this phenomenon,models are established through the structural parameters of saw blades with different corrosion degrees,and modal analysis of saw blades with different corrosion degrees is carried out.This ana-lysis takes sawing vibration as a reference index of stability and studies the influence of saw blade corrosion on stability.Experiments verify the accuracy of the results.The results show that the vibration modes of the corroded saw blade more are more than 6 orders different from those of the original saw blade,and the difference in adjacent natural fre-quencies reduces by 8.56％in the frequency range of 640 to 1,280 Hz.With the increase of corrosion degree,the saw blade is more prone to resonance.Corrosion at the important position has a great influence on the sawing stability of the saw blade.Reducing surface defects can reduce corrosion and its influence on the sawing stability of the saw blade.This study provides guidance for the practical use and rust prevention technology of diamond circular saw blades.
