low price disc for metal and grinding wheel in terms of hardness


low price disc for metal

Abrasives and grinding wheels are the grinding tools we often use in our daily life, but many people don’t know much about the hardness of abrasives and low price disc for metal. Let’s take a look at the abrasives and grinding wheels in terms of hardness. What is different.
1. The hardness of the abrasive is the conventional hardness, that is, the ability to resist local plastic deformation. That is, the hardness is generally said. The hardness of the grinding wheel refers to the ability of the abrasive to fall off from the grinding wheel. If it is easy to fall off, the hardness is low, and the hardness is not easy to fall off.
2, because the abrasive will be blunt, to a certain extent these abrasives are useless. These useless abrasives should be able to fall off automatically under the action of cutting force to ensure the sharpness of the grinding wheel. The ability to shed is to take a balance point between the sharpness of the grinding wheel and the durability of the grinding wheel. The hardness of the grinding wheel is inversely proportional to the hardness of the workpiece. The hard workpiece is made of the soft grinding wheel and the soft part is made of the hard grinding wheel.
In summary, we have learned that the hardness of the grinding wheel refers to the difficulty of the abrasive particles falling off from the grinding wheel. The hardness of the abrasive refers to the difference of the abrasive itself. The two have the advantage of partitioning. Generally, when we are rough grinding if the workpiece is If the hardness is relatively high, we should choose a grinding wheel with a softer hardness to improve the grinding efficiency.

Grinding wheels are tools for grinding, grinding and polishing. In the grinding work, a good grinding plate can not only improve the efficiency of the grinding work, but also the grinding result is better than the work efficiency of the ordinary grinding wheel. There are many types of grinding wheels on the market today. What are the more commonly used ones?
1. The grinding wheel is made of super-hard material. The grinding wheel-solidified grinding tool can be divided into ordinary abrasive-consolidated abrasive tools and super-hard abrasive-solidified abrasive tools according to the different abrasives used. The former uses ordinary abrasives such as corundum and silicon carbide, and the latter is made of superabrasives such as diamond and cubic boron nitride.
2. According to the shape, it can be divided into a flat grinding wheel, a beveling grinding wheel, a cylindrical grinding wheel, a cup-shaped grinding wheel, a dish-shaped grinding wheel, etc.;
3, according to the bonding agent can be divided into ceramic grinding wheel, resin grinding wheel, rubber grinding wheel, metal grinding wheel and so on.

The grinding wheel is one of large amounts of abrasive tools and widely used. Most of the grinding tools are artificial abrasives made of abrasives and binders, and also abrasives directly processed from ore. High-speed rotation during use can perform rough grinding, semi-finishing and fine grinding, and grooving and cut on the outer circle, inner circle, plane and various profiles of metal or non-metal workpieces. A good super-hard grinding wheel not only improves work efficiency but also has a longer service life than ordinary products and can be used continuously.
