Abstract
In dry grinding of hard carbon parts, the loading by carbon chips on wheel surface occurs in early grinding process, and the grinding performance of wheel is extremely declined. The deterioration affects the grinding accuracy and efficiency. Therefore, loading is one of the problems that must be resolved for high efficiency and high quality grinding of carbon. Generally, the grinding performance of wheel is recovered by the dressing. However, it's not suitable from a viewpoint of the wheel life and the production cost because available abrasive grains possessing sharp edges under loading carbon chips on wheel surface are lost by dressing. In this study, we propose the dry ice blasting for removing loading carbon chips on wheel surface. The dry ice particles impact on pressed carbon chips with high pressure and sublimate to carbon dioxide quickly. Therefore, it is little influence on working environment because the dry ice doesn't remain on wheel surfaces after blasting without the damage. In this report, we carry out the blasting tests of resinoid bond diamond wheel surface without grinding performance by loading carbon chips, and analyzed the effect of nozzle processing speed and nozzle feed pitch on recovering abrasive protrusion. The effective dry ice blasting conditions are investigated for high efficiency removal of loading carbon chips, analyzing the protrusion height of abrasive grains.
