A study on the grinding of engineering ceramics with high quality using conventional grinding machine

In this study, grindability of some representative engineering ceramics are experimentally investigated using resin bond diamind wheel with conventional surface grinding machine. And the optimum machining process step considering such various results as total machining cost, total machining time, and ground surface layer quality which is proper to domestic circumstances for manufacturing of the mechanical component is investigated also. Furthermore, each proper dressing process and condition suing WA stick type dresser for the most effective dressing of resin bond diamond wheels with various mesh number is established experimentally. Through the results of experiment, it is confirmed that there is scarecely any difference for improving ground surface roughness using diamond wheel with over mesh number 1000 in this experimental conditions. And it is confirmed also that 3-step type grinding process using diamond wheel with mesh number 120, 600, 1000 with proper machining conditions is the most useful case in the view of economic productivity for manufacturing of mechanical components. And moreover, the total table pass number needed for sperk-out process to be completed for removing unmachined quantity depend on their mechanical properties because that dynamic grinding stiffness is different from each other. The grinding force, grinding power and ground surface roughness are also measured and compared. Through the experiments carried out in this study, some useful results are obtained which can guide to grind engineering ceramics with conventional surface grinding machine.
