Diamond has a hard resistance, so the tool is made of special materials are particularly suitable for processing hard and brittle non-metallic materials, such as stone, tiles, glass, ceramics, concrete, refractory materials, magnetic materials, semiconductors, and other precious stones; also be used for processing non-ferrous metals, alloys, wood, such as copper, aluminum, carbide, hardened steel, cast iron, wood and other composite wear. At present diamond tool has been widely used in construction, building materials, petroleum, geology, metallurgy, machinery, electronics, ceramics, wood, automotive and other industries. I am in domestic and international diamond brazing study on the use of vacuum furnaces (vacuum degree 0.2Pa) high temperature brazing method to NiCr13P9 alloy solder, together with a small amount of Cr powder at a high temperature (950 ℃) plus brazing under pressure (4.9MPa) the conditions to achieve a solid combination of diamond and steel substrate between. Solder evenly distributed in the wheel surface, diamond is firmly brazed touch wheel surface feels quite rough and sharp. Solder evenly distributed between the diamond abrasive, diamond protrusion height high. Its durability has been significantly improved compared with the electroplated grinding wheel, only a small amount of diamond loss after work. Brazed diamond tools just so users can quickly be recognized that the nature of its structure itself that decides 1, diamond head high, cutting and grinding efficiency is very high; 2, diamond is firmly soldered solder the matrix on the parcel is not mechanical but chemical binding, so easy to fall off the diamond at work. Brazing technology enables Diamond, binders (brazing alloy) and metal matrix interfacial chemical metallurgical bonding, with high bonding strength. Due to the high bonding strength of the interface, so that only a thin binder thickness is sufficient to firmly hold on grains, which exposed up to 70% to 80%, so that more fully utilize abrasive, greatly improving the tool life and processing efficiency. Compared with traditional technology, diamond tools allow maximum protrusion value increased more than 50%, increase in power tools or decreased without conditions, on a volume of diamond consumption reduced by more than half of the workpiece material. Compared with the plating tool, also shows the unparalleled advantage. Performance high temperature brazing diamond tools is much superior to electroplated diamond tools, soldering tools (using active brazing and PDA989, PDA665 diamond) Start grinding performance over electroplated tools (nickel-based filler material and PDA665 diamond) of 3.5 times , life is more than three times the electroplating tools; the solder welder has a large chip space, diamond abrasive cutting face greater freedom and more space between the grains, the chips can be easily removed, so the brazing Good grinding performance of diamond tools. Conventional diamond particle size in the range of 30/35 ~ 60/80. The more hard rock, should be selected with a finer granularity. Because under the same pressure conditions, the more detailed the more sharp diamond, cut in favor of hard rock. In addition, the general saw blade sawing large diameter high efficiency, should be chosen with coarse granularity, such as 30 / 40,40 / 50; lower small-diameter blade cutting efficiency, cutting cross-section requires smooth rock, should selection of finer particle size, such as 50/60, 60/80.
