Study On Sinter Process And Grinding Performance Of Environmental Friendly BCB Grinding Wheel

ELID is a main technology which has been widely adopted to the ultra-precision and high effectively machining of hard and brittle materials. With the development of the research and application of new materials and precision devices, requires of surface quality become higher and higher. Metal-resin bonded wheels is the main tool in ELID but it's difficult to produce and expensive and could contaminate the clean surface of function materials. To ease this problem, this paper puts forward a new environmental friendly BCB (bamboo charcoal bonded) grinding wheel, a new ultra precision manufacturing technology which is more convenient to get a better surface quality is proposed and provide a new method and approach for the development of the ultra precision machining technology.Refer to the conventional grinding wheel manufacturing processes, according to characteristics of the technical features of ELID technology, a new manufacturing process of BCB grinding wheel is established in this paper and also the perfect processing process.Reference to the parameters of traditional grinding wheel's detection methods, chose hardness, compressive strength and friction wear coefficient of the key parameters as BCB grinding wheel 's evaluation parameters and construct evaluation system of the BCB grinding wheel. And the effect of different manufacturing parameters on the grinding wheel structure is also studied by XRD and SEM.A heat pressing process simulation is established by ANSYS which is a well used kind of finite element analysis software and the curing process of the phenol formaldehyde resin in the heat pressing process is studied to optimize the processing parameters of the heat pressing process and improve the performance of BCB grinding wheel.Study the machining characteristics of BCB grinding wheel in grinding experiments with appropriate parameters. The grinding ratios of BCB grinding wheel on SUS304 non-corrosive steel is about 1 and surface roughness of workpiece is 0.02μm. The experimental results show that BCB grinding wheel is a super precision grinding tool with excellent characteristics.
