复合电刷镀金刚石线锯的制备工艺研究

摘要

The effect of process parameters on the performance of wire saw was analyzed by self-made composite brush-plating manufacturing device,and the optimum process parameters were found out.Based on making clear the determination of the permissible current density,the effect of process parameters on the distribution density of abrasive grains was investigated by single factor experiment and orthogonal experiment.The experimental results showed that the permissible current density increased and then decreased with increasing felting speed,and the permissible current density reached the extreme value at 300 to 500 r/min,when there was no abrasive particles in the plating solution.The main factors affecting the distribution density of abrasive grains were the wire speed,the current density,and the felt speed.The maximum parameters of abrasive distribution density were:wire speed 15 mm/min,current density 19 kA/m2,felt speed 450 r/min.%使用自制电刷镀金刚石线锯制备装置研究金刚石线锯的制备工艺,分析各工艺参数对线锯性能的影响规律,并优化工艺参数.在确定电刷镀装置许用电流密度的基础上,通过单因素试验及正交试验研究工艺参数对磨粒分布密度的影响规律.结果表明:镀液中无磨粒时,随着毛毡轮转速的增大,许用电流密度先增大后减小,转速在300～500 r/min时,许用电流密度达到极值;影响磨粒分布密度的因素主次顺序依次是走丝速度、电流密度、毛毡轮转速;磨粒分布密度最大值对应参数组合为走丝速度15 mm/min、电流密度19 kA/m2、毛毡轮转速450 r/min.
