Experimental Study on Machining Mechanism and Process of ELID Precision Grinding of Stainless Steel Materials
Stainless steel material because of its stable chemical properties and high mechanical strength is widely used in industrial production and all kinds of tools.There are problems such as poor thermal conductivity,high toughness,high thermal strength and coefficient of linear expansion in the traditional grinding processing of stainless steel materials,which leads to low precision,poor surface quality and easy burns in the finished workpieces processed by traditional grind-ing.In this paper,ELID grinding technology is used to carry out precision grinding processing experiments on ferritic stain-less steel materials,through orthogonal experiments,to explore the influence of processing process parameters on the pro-cessing surface quality of the law,to obtain the optimal combination of process parameters and experimental verification.The experimental results show that the optimal combination of process parameters:grinding wheel grit size 1200#,grinding wheel feed 0.02mm/r,grinding wheel linear speed 2200r/min,electrolytic current 4A,can realize ELID precision grinding pro-cessing of stainless steel materials,to obtain the surface roughness of the sample Ra 0.165μm,64％ lower than the tradi-tional grinding roughness,and the processing of the surface without burns.
