Research on PDC processing technology based on ELID grinding and polishing technology
英文摘要
Aiming at high hardness,low precision and other defects of polycrystalhne diamond(PDC) during processing,in the semi-fine grinding stage,the ELID grinding technology was used to study the removal mechanism and the defects in this article.In order to solve the defects in ELID grinding PDC,polishing experiment of PDC was studied in the finishing stage.Taking into account the impact of PDC surface roughness about process parameters,polishing experiment was designed by using the method of quadratic general rotary unitized design.First of all,the experimental results were analyzed in order to get secondary regression mathematical model and univariate and interaction influence of PDC surface roughness by using DPS data processing system software.Then,optimum process parameters with the polishing pressure of 80 kPa,polishing disc speed of 1 200 r/min,the polishing liquid abrasive particle size of 2 μm and polishing time of 45 min is obtained by Lingo software.And the machined surface roughness of Ra15 nm is obtained under the optimum process parameters.
