    Abstract

    This study aims at improving the grinding quality and efficiency of the grinding edges on tempered glass using electroplated diamond abrasive belts. Firstly, the most suitable diamond type and composition of metal coating were selected in the first experiment. Secondly, the structure parameters of abrasive belts, such as diamond grain size (dgs), chip clearance (chc), matrix thickness (mt), and coating thickness ratio (ctr), were optimized through an L9 (34) orthogonal experiment. Finally, the influences of the process parameters on the grinding effect were investigated, which are optimized by an L9 (33) orthogonal experiment. The results show the following: (1) the abrasive belt with the diamond type of SMD40 and metal coating of 90 % nickel, 5 % cobalt, 5 % copper (Ni90%-Co5%-Cu5%) weight percentage (wt.%) of the total weight of the coating metal possesses the best grinding performance for the grinding edges on tempered glass. (2) The best grinding quality can be achieved under the conditions of the 230/270 US mesh (63-53 μm) in dgs, 1.5 mm in chc, 1.2 mm in mt, and 2/3 in ctr. (3) The roughness decreases first and then increases with the increase of dgs and ctr, decreases with the increase of chc, and increases with the increase of mt. (4) With the increase of the grinding pressure (gp), the roughness increases, and the material removal rate increases first and then decreases; with the increase of belt linear velocity (blv), the roughness first descends and then tends to stability, and the material removal rate increases first and then decreases; with the increase of the belt tensioning force (btf), the roughness decreases, and the material removal rate increases first and then tends to be stable. (5) The best grinding performance can be achieved under gp of 18 N, blv of 30 m/s, and btf of 55 N.
