Pottery wheel performance

Ceramic grinding wheel is a cutting tool, which consists of many small and hard, abrasive and adhesive binders from the porous body. Abrasive cutting directly responsible for the work, sharp and must have a high hardness, heat resistance and a certain toughness. Commonly used abrasive alumina (also known as corundum) and silicon carbide two kinds. Alumina-based abrasive, high hardness, good toughness, suitable for grinding steel material. Type silicon carbide abrasive hardness higher, sharper, good thermal conductivity, but more brittle, suitable for grinding cast iron and tungsten carbide.
For the same abrasive grinding wheel, because of its different thickness, surface roughness and processing efficiency is not the same after the workpiece, coarse grains for rough grinding, fine abrasive grains, the more rough abrasive grain size number smaller.
Binding agents from bonded abrasive effect. Commonly used ceramic binders, followed by the resin binder. Different binders choice of materials, the impact wheel corrosion resistance, strength, heat resistance and toughness.
The more firmly bonded abrasive particles, the more difficult to fall from the wheel, the hardness of the wheel is said that the hardness of the wheel is the degree of difficulty of the stainless steel cutting wheel surface under loads off. Easy to fall off called soft, otherwise known as hard. The abrasive grinding wheel hardness and hardness are two different concepts. Surface grinding of the workpiece is relatively soft, abrasive cutting edge (corner) on easy to wear, this time may be longer use abrasive, that some of the firm bonding optional wheels (high hardness of the wheel). Conversely, a low hardness grinding wheel for high hardness workpiece.
Ceramic wheel at high speed work, in order to ensure safety, should be checked before installation, there should be no cracks and other defects; in order to make the wheel steady, balancing test should be carried out before use.
concrete cutting blade after working a certain time, the surface voids are clogged debris, abrasive acute angle blunt, the original geometry will be distorted. It must be trimmed in order to restore the cutting ability and the correct geometry. Required diamond grinding wheel dressing pen.
