| Abstract: | 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 a... |
