We recently did some test cuts on Barium Titanate to determine the best abrasive size for that particular material. We tried different size diamond and found out that this material is much like a ceramic in that it cuts better with large diamonds. We tried 325, 270, and 140 mesh; it was obvious that the larger diamonds cut this material better. Chipping is not an issue like with most ceramics. This material was .050? thick and we diced in one pass using a .010? blade. We determine that 140 mesh is an ideal mesh for this material and that a feed rate of .1?/sec gives better results. We used our resin bond blades which can be custom made to virtually any size and for almost any application. Here are some microscope images of the top view as well as the side view of the cuts.
