Analysis of the Effect of PCBN Grit on the High-Speed Grinding Force of In625 Nickel-Based Alloy
In order to improve the understanding of the machining performance of nickel-based alloys,the design of PCBN grits on In625 nickel-based alloy high-speed grinding test programme,through the MV-40 high-speed grinding experiments on In625 grits,and analyse the changes in the degree of wear.The results show that when the number of grinding times is increased,a larger grinding force is formed,and the grinding force also has an obvious effect on the degree of wear of the cutting edge of the PCBN grits,and the grits are subjected to a larger grinding force,which results in wear fragmentation and causes a reduction in the grinding force.When the number of grinding is gradually increased,the grinding force ratio first increases and then decreases,and the grinding efficiency first decreases and then increases.After increasing the depth of grinding,a larger grinding force was formed,which caused more serious abrasive wear and more micro grinding edges were generated.
