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.

Synthetic diamond market conditions
With the early 1970s, massive synthetic diamond and the emergence of the mid 1980s, the diamond film to enter the market, and the significant decline in the cost of
production of synthetic diamond, diamond sharp increase in consumption, the current international market for synthetic diamond total of
Demand has more than one billion kt. Consumption is mainly stone processing, concrete cutting, machining, glass processing, geological drilling, oil and gas
exploration and electronic industrial processing semiconductor materials, production drawing dies and so on.
20th century, 90 years ago, our main market is the synthetic diamond machinery, geology, petroleum, drilling and other industries, to account for about 60% to 70%. In
the 1990s, due to the development of stone processing industry, led the development of synthetic diamond industry for Stone
Timber processing industry, the number of synthetic diamond straight up, now its consumption of synthetic diamond production accounts for about 70% or so. In recent
years, China's oil and gas exploration continued to heat up, especially in the western development on oil exploration, natural gas, etc.
The construction of large projects, strong demand for diamond tools. In recent years, according to the geological drilling assignments, hydropower, coal chemical and
other statistical data, we estimate the market demand for diamond drill geology is estimated at 15 to 200,000, consume about 350 ~ 4.5 million diamond
Carats. PCD drill domestic oil drilling composite sheet production can not meet demand, and low quality, currently need to import. Therefore, the oil and gas industry
is a promising diamond market.
2000 China's auto production reached 2,000,000, the 2005 car production will reach 3.5 million. But so far, the domestic diamond tool machining difficult to meet the
automotive industry, the introduction of a large number of complete sets of automatic production line needs, and imported from abroad. Therefore
, The domestic market is the machining tool has the potential for future expansion and occupation of the market.
In recent years, China's communications industry, ceramic industry developed rapidly, and the development prospects of a better future, therefore, drawing film and
ceramics with polycrystalline diamond tools will greatly increase the potential market is large. At present, China actively explore the international diamond market. As appropriate
Chang Black Whirlwind brand diamond saw blades base for export to Germany is expected to reach $ 1 million, accounting for 18% of all products to 20%; while the
production of diamond tools of the old enterprises IOL Institute laser welding diamond saw blade exports to the U.S. are expected to exceeded 10,000.
