Preparation and abrasive wear characteristics of orderly arrayed diamond saw blades

The multi-layer orderly arrayed diamond saw blades were prepared by a novel orderly arrayed micro-hole adsorbent method with the grit volume fraction of 20%. Cutting tests of G664 granite were carried out by using the orderly arrayed diamond saw blades and the randomly arrayed saw blades, respectively. The cutting electric current, tangential cutting force of single grit, and wear morphology of diamond grits in the cutting tests were studied and analyzed. The effects of orderly arrayed diamond grits on cutting performance and abrasive wear characteristics were investigated. The results show that, the cutting electric current and single grit tangential cutting force of orderly arrayed diamond saw blades are lower than those of randomly arrayed saw blades. Both in the dry and wet cutting conditions, the abscission particle fraction of diamond grits in total quantity of diamond grits of orderly arraying diamond saw blades is lower than that of randomly arrayed saw blades, and the particle number fraction of diamond grits in micro-fracture and macro-fracture of randomly arrayed saw blades is higher than that of randomly arrayed saw blades.
