Research on mirror finishing optimization process of polycrystalline diamond compact
摘要
Abstract
In order to satisty the requirements of making the surface of polycrystalline diamond compact after finishing bright and clean,like mirror surface,based on the orthogonal test method,it is to optimize polycrystalline diamond compact finishing process parameters combination,using the method of range analysis to process data,and draw test index and the relationship between each experimental factor graph to obtain the influence degree of various factors on the surface roughness value,and as a basis for opti-mization parameters,optimizing the parameters of polycrystalline diamond compact process optimization research. Research showed that the rotation speed and the finishing time put greater impact on the working surface quality,and the influence degree of various factors on the surface roughness size in order from large to small is:polishing disk rotational speed,the time,the polis-hing pressure,and the polishing liquid abrasive granularity.Using the optimized processing test for the optimal process parameters combination,when lapping and pressure is 90 kPa,polishing disk rotational speed of 1 200 r/min,polishing liquid abrasive parti-cle size is 1 μm,and polishing time for 30 min,got the quality of the surface roughness Ra is 0.019 μm surface,mirror surface treatment effect (Ra<0.02 μm)was realized.关键词
