摘　　要：为了克服非金属基材料的非导电性和弱导电性,提出了在表面涂抹导电介质的电火花放电修整非金属基金刚石砂轮方法.利用电火花成型机床在空气介质中进行电火花修整树脂基金刚石砂轮实验,研究了修整过程中的不同放电参数对修整效率的影响,用三维数字显微镜观察电火花修整前后金刚石砂轮表面的微观形貌,比较了放电参数作用下不同的修整效果.In order to overcome the weak conductivity of non-metal bond,a method that smears the wheel surface using conductivity medium was used.Experiments on dressing resin bonded diamond grind wheels were carried out on a die-sinking electrical discharge machine.The influences of different electrical parameters on wheel dressing efficiency were studied.The diamond wheel topographies before and after electrical discharge dressing were observed by VH-800 three dimension digital microscope.The wheel profiles before and after dressing were observed.The results of electrical discharge dressing under different electrical parameters were compared.
