What are the principles for selecting the hardness and softn

The selection of grinding wheel blade is an important part of the abrasive tool industry. A good grinding wheel blade should have good sharpness and hardness conditions. Therefore, when selecting the grinding wheel, it reminds you to consider the abrasive type, particle size, abrasive bonding degree and abrasive structure.

There are two kinds of traditional abrasive particles: alumina or silicon carbide;

There are also two types of unconventional abrasive particles: diamond or cubic boron nitride.

The size of abrasive is called particle size. The larger the number of abrasive particles, the finer the particle size. Fine abrasive particles are suitable for fine grinding or grinding of brittle and hard materials, while coarse abrasive particles are suitable for coarse grinding or grinding of soft and tough materials.

The principle of selecting the hard and soft grinding wheel: the soft grinding wheel is suitable for grinding hard materials or large-area workpieces, while the hard grinding wheel is suitable for grinding soft materials or small-area workpieces.

The combination of abrasive grains and abrasive grains is the manufacturing method of grinding wheel. The commonly used methods of combining abrasive grains with materials in industry include clay method, water glass method, resin method, metal method, shellac method and rubber method.
