Abrasive hardness depends mainly on the amount of binding agent is added to the number and density of abrasive grit off easily, said lower abrasive hardness; the other hand, indicates a high hardness. Hardness level is generally divided into super soft, soft, soft, medium, medium-hard, hard and superhard seven level, from these levels can be subdivided in a number of small magnitude. The method of measuring the hardness of abrasive, more commonly used hand cone, mechanical cone method, Rockwell hardness measurement method and blasting hardness assay. Hardness of the dynamic elastic modulus of the abrasive has a corresponding relationship, which is conducive to the determination by the abrasive audio method to represent the dynamic elastic modulus abrasive hardness. In the grinding process, high if they are grinding the workpiece material hardness, cutting discs, generally used in low hardness abrasive; on the contrary, the selection of high hardness abrasive. Since the cut sheet manufacturing and installation of a variety of reasons, the focus of its rotational center of cutting blades are often not bundle together, this will cause the wheel vibration during high-speed rotation, ranging from the impact processed into strict in time will lead to cracking and cutting discs damage to the machine, it must be static balance sheet after cutting the cutting blade is mounted on the flange. After cutting chip mounted on the flange, the flange on the mandrel, and then on the balance frame rail. If the imbalance, cut pieces heavier part always go to the following balance flange end face of the block position within the annular tip, Gu Yuan whole heart cut sheet balance, repeatedly, until the cut pieces on the rails at any bits can be stationary, then cut pieces static equilibrium. Install the new cut sheet, cut sheet plant, cut pieces to a static equilibrium twice. After the undertaking of a static balance sheet price cut, mounted on grinder with a diamond pen for cutting sheet shape trimmed, cut and remove the static balance sheet once again in order to install and use. Resin Manufacturing thin diamond cutting disc is a way to get a good shape retention methods, cutting discs wholesale, generally use thermosetting phenol resin as a binder, it is the practice of diamond abrasive grains mixed with the resin, and then pressing Sintering and thermal post-cure lapping, this process takes hours, so the higher production costs. As technology advances, a thermosetting resin is gradually replaced by the photo-curable resin, photo-curable resin is mainly composed of the base polymer (photo-crosslinkable polymer), reactive diluent (photopolymerizable monomer), a photoinitiator and an additive components. The difference between it and the thermally curable resin is most essential in its curing process is the absorption of the appropriate wavelength of light caused by a chemical reaction process, which from liquid to solid is the result of increased molecular weight, rather than caused by solvent evaporation, it has a fast cure , non-polluting, energy-saving advantages, but the constraint is its higher raw material prices.
