Diamond grinding disc for grinding of cast iron

Single-crystal diamond tool manufacturing processes generally include material selection, orientation, sawing, cogging, installed cards, rough grinding, fine grinding and inspection. Will be selected by the directional diamond original stone after sawing along the  carbide drill bits biggest open plane, get two tool blanks, so that both improve the utilization of diamond material, but also reduce the total amount of polishing. Blooming through the tool can shape up chucking (mosaic or brazing) requirements. Cogging and coarse, fine grinding polishing methods are used.Diamond grinding disc for grinding of cast iron. Grinding disc diameter of about 300mm, organized by the material pore shape, size and proportions of the diamond abrasive are optimized special high phosphorus cast iron. Grinding disc surface inlaid  metal grinding wheel with diamond abrasive powder, the particle size can be from less than 1μm until 40μm. Rough diamond powder particles having a high polishing rate, but poor quality grinding, generally used so coarse meal, and is used when grinding the powder size of less than 1μm. Before grinding, first diamond powder with olive oil or other similar substances mixed into a grinding paste, and then coated on the surface of the grinding plate, place some time for the grinding disc grinding paste to fully penetrate the pores of the cast, and  ring saw blades then a large diamond in pre-grinding disc surface grinding back and forth in order to further strengthen the diamond powder in the cast iron pores mosaic effect. Grinding, polishing the diamond will generally be embedded in a tin bucket, revealing only a surface to be polished. Abrasive grinding disc speed is about 2500r/min, grinding pressure of about 1kg/mm2.
