The grinding wheel is a porous body formed by adding a binder to the abrasive, pressing, drying, and firing. When in use, it rotates at high speed, and can perform rough grinding, semi-finish grinding, fine grinding, slotting and cutting off the outer circle, inner circle, plane and various contours of metal or non-metallic workpieces. Due to the difference in abrasives, bonding agents, and manufacturing processes, the characteristics of grinding wheel discs are also very different. It has an important impact on grinding quality, productivity and economy.
Which specification of the grinding wheels are better? How can the grinding wheel work safely and efficiently?
A good uniform appearance without cracks is the basic appearance of high-quality grinding wheel disc specifications.
The general law of cutting and grinding is that the grinding wheels are too hard to remove less iron, and the wear is low. The materials used are too poor, less iron removal, and high wear. The inherent quality of high quality is the less wear and tear the better. Maximum iron removal, good hand feeling.
The lower the static unbalance value of any grinding wheel, the better, and of course the more difficult it is to produce.
The choice of grinding wheels depends on the material to be ground, the ideal grinding wheels should have good sharpness and hardness. After the abrasive grains are passivated, whether they will automatically fall off from the bond and keep the grinding wheel in a good sharp state at any time is an important criterion for the safe and efficient work of the grinding wheel.
Excellent packaging and printed anti-counterfeiting barcodes are the difference between genuine and fake products.
For carbon steel, alloy steel, cast steel, stainless steel, copper aluminum, glass and stone. Due to their different tissue density and heating conditions, it is determined that the grinding wheel should be selected differently. For glass stones, there are special glass stone cutting and polishing tools on the market. Copper and stainless steel solid materials should be cut or polished to lower thickness or zirconium corundum as the base material. Cutting carbon steel and stainless steel profiles (not solid), requires the selection of a grinding wheel with higher hardness. This will greatly increase the service life. But for solid round steel and forgings, it is required that the hardness of the grinding wheels should not be too high, otherwise it cannot be cut!
