Wheel must be used with safety guards. The actual rotational axis of the wheel and its axis of rotation through the center of mass deviation from parallel state called static unbalance wheel. This is usually due wheel uneven density, both ends of the hole and the surface is not parallel or coaxial cylindrical deviation has caused.

Cut thin resin used in the fields of domestic cutting blade
Many microelectronics and precision optical components manufacturing enterprises, precision cutting technology in the production process is a key processing technology. The technology used in high-precision ultra-thin cutting blade more than 90% of imported products, the price is expensive, as this will increase the use of manufacturers in production costs, and ultimately weakened the products in the international
abrasive wheels . To achieve precision cutting thin resin used in the fields cutting blade localization of abrasive production of domestic enterprises and research institutions from the 20th century in the late 1990s began cutting blade thin resin research. Most of them follow the traditional resin abrasive
polycrystalline diamond technology and processes, which uses a thermosetting resin as a binder, the use of sintering furnace or hot press heated to 220 ~ 250 ℃ high temperature, at about 100MPa pressure conditions, pressure, heat number forming hour. The manufacturing process of high energy consumption, high time-consuming, while often also volatile toxic solvents, which cause some pollution to the environment. Light-cured resin as a new rapid manufacturing polymer materials, coatings and three-dimensional printing and other industries has been widely used.
