Advantages of electroplated grinding wheels
There are many types of grinding wheels. We all know that there is a kind of electroplating durable cutting off wheel. Do you know if you know the electroplating grinding wheel? If you don't know, let's take a look! What are the advantages of electroplated grinding wheels?
First, high hardness The electroplated grinding wheel is usually electroplated with nickel or nickel-cobalt alloy as a binder. The electroplated metal bonding agent itself has a high hardness and high density. In addition, the compactness of the structure and the strong bonding force make the overall hardness of the working layer significantly higher than that of the bronze abrasive. And resin abrasives.
Second, the porosity is low Ordinary sintered grinding wheels often have a porosity of several tens of percent. Although the resin binder and the bronze binder are relatively tight, a few percent of the porosity is also used. Electroplated products have the lowest porosity and almost zero, which is the most compact of all abrasive tools.
Third, strong combination In the electroplated grinding wheel, the metal bond in the working layer is the most tightly packed with abrasive grains, the contact is the most complete, the consolidation is the strongest, and the holding power is the largest. It is because of the strong bonding property that the electroplated products are allowed to use high concentration without It will cause the abrasive to fall off prematurely. This property is unmatched by powder molding.
Fourth, the concentration is high In the powder-formed grinding wheel, the concentration of the abrasive in the working layer is generally 50%~150%, and the volume occupied by the abrasive is about 10%~30%. If the abrasive concentration is too high, the abrasive is too early in use due to the insufficient setting of the abrasive. Shedding, while the concentration of abrasives in superhard material plating products is very high, generally around 200%, the volume of abrasives is 50%, and even higher, reaching more than 65%, if some measures are taken, such as scaling in diamonds Add some abrasive particles just to reduce the concentration appropriately.
