摘要
为了改善金刚石线锯切割中切割液的润滑冷却效果,提高工件切割质量,利用静电喷雾供液方式替代传统浇注供液方式,并对静电喷雾供给的切割液荷电液滴进行了运动学分析,仿真研究了不同电压下荷电液滴的吸附特性.在此基础上进行了切割液浇注供给方式和静电喷雾供给方式的金刚石线锯切割试验,以切割后的崩边宽度和表面粗糙度作为切割质量的评判参数.结果表明:与浇注式供液方式相比,静电喷雾式供液方式能够有效地降低崩边宽度和表面粗糙度;当荷电电压为-6 kV时,崩边宽度和表面粗糙度达到最小值,分别为44.78μm和0.409μm.
To improve the lubrication cooling effect of cutting fluid in diamond wire sawing and improve the cutting quality of workpiece,electrostatic spraying liquid supply method was used instead of traditional pouring liquid supply method,the kinematic analysis of charged droplet of cutting fluid supplied by electrostatic spraying was carried out,and the adsorption characteristics of the charged droplet were simulated at different voltages.On the basis of this,the experiment of pouring liquid supply method and electrostatic spraying liquid supply method diamond wire sawing was carried out,and the edge breakage width and surface roughness were used as the judging parameter of the cutting quality.Results show that compared with pouring liquid supply method,electrostatic spraying liquid supply method can effectively reduce the edge breakage width and surface roughness,and when the charging voltage is-6 kV,the edge breakage width and surface roughness reach the minimum value,which are 44.78 and 0.409μm,respectively.
