Layer of tissue electroplated grinding wheel: the work layer electroplated diamond grinding wheel is the electric crystal formation, it is compared with the powder molding layer has the following characteristics:
1 the highest concentration. Powder molding of the wheel, the abrasive concentration in the working layer is generally 50% to 150%, corresponding to approximately 10% to 30% of abrasive volume occupied; if the abrasive concentration is too high, the abrasive due to package inserts is not strong in use prematurely shedding. The concentration of abrasive in the superhard materials electroplating products is very high, generally about 200%, the abrasive volume occupied by 50%, or even higher, up to 65% or more. If you take some measures added in proportion to the number of abrasive particles, such as thin cutting wheel, just may be appropriate to reduce the concentration.
With the strongest. Work layer electroplated diamond grinding wheel, metal bond abrasive package inserts most rigorous, contact the fullest, consolidation is the most firmly gripping force maximum. It is due to a combination of strong characteristics allowed electroplating products using high concentration of abrasive without causing premature loss. This feature is a powder molding can not match.
Lowest porosity. Ordinary sintered wheel porosity often up to several tens of percent, although the use of the resin binding agent and a bronze bond more closely, but also commonly used by a few percent porosity. The electroplating products stomatal the lowest rate of almost zero. It is the most dense one organization in all abrasive.
4 high hardness. Electroplated diamond wheel is usually electroplated nickel or nickel-cobalt alloy as a binder the plating metal binder itself has high hardness and high dense and strong combination, coupled with the organization, making the overall hardness of the working layer significantly higher than bronze grinding tools and resin Abrasives.

CBN grinding wheel in recent years more and more widely exposed to in our lives, then this product CBN wheel you understand it? Introduction about it, what does? Details are as follows:
CBN wheel (cubic boron nitride) abrasive materials, respectively with the metal powder, a resin powder, ceramic, and the plated metal as a binding agent, to prepare a variety of shaped articles, for grinding, polishing, grinding tools called CBN grinding with.
(CBN) abrasive CBN grinding wheel structure is generally composed of three parts by the working layer, substrate, buffer layer.
Working layers, also known as the CBN layer, by the abrasive, the binding agent and the filler composition, the working portion of the abrasive. The transition layer is also known as non-CBN layer by the binding agent, a metal powder and a filler composition, is the portion of the CBN layer is firmly connected to the base body.cutting wheel
The substrate is made from aluminum, steel, or bakelite processing, since the role of supporting the working layer and the loaded card abrasive.
