单晶金刚石微型刀具刃磨试验研究

采用金刚石砂轮对单晶金刚石微型刀具进行了刃口机械刃磨试验,利用莱卡光学显微镜观察了单晶金刚石刀具刃口和表面形貌,以研究不同参数对磨削过程的影响,通过优化相关参数来获得更好的单晶金刚石微型刀具并提高刃磨效率。试验选择砂轮粒度、磨削速度以及进给速率作为刃磨参数。通过正交试验设计,比较磨削力、刃口半径和表面形貌,从而筛选出最优参数。试验得出小粒度砂轮、较高磨削速度和中等进给速度可以得到较好的刃磨结果。

Experimental Research of Single Crystal Diamond Micro-tool Sharpening

Diamond grinding wheels were used for single - crystal diamond micro - tool cutting edge mechanical grind- ing reseach. Observed single - crystal diamond tool edge and surface morphology by using an optical microscope Leica, to study the effect of different parameters on the grinding process and optimize them, for better tools and high micro - crystal diamond grinding efficiency. Wheel size, grinding speed and feed rate were chosed as the grinding parameters. By orthogo- nal experimental design, compared grinding force, edge radius and surface morphology, to filter out the optimal parameters. It is showed that small particle size wheel, high speed and medium grinding feed rate can get a better sharpening results.
