The University of Hong Kong successfully developed micro wind turbines

This miniature wind turbine, jointly developed by the University of Hong Kong professor and the French inventor, uses a specially designed plastic wheel with a diameter of only 26 cm as a means of obtaining wind energy.
Such rollers can be assembled into any shape and size. It can be installed on the terrace of a home or on the roof of a building. The generated electricity is first stored in the battery and can be used to drive household appliances.
According to the inventor, the wind power system can generate electricity when the wind speed is only two meters per second. The traditional small wind turbines must increase the wind speed to 7 meters per second to generate electricity efficiently. The average wind speed in most cities around the world is 5 meters per second.

Super Abrasives


Superabrasives come in the form of grinding wheels and are used when the material being processed is either too hard or too delicate for regular abrasives.

Industrial diamonds are one of the most common materials used to create the grinding material. Contrary to popular belief, diamonds are not as rare as marketing campaigns will tell you.

After diamonds,cubic boron nitride is the second more durable material for cutting. This is followed by polycrystalline.

The most obvious advantage is that these Grinding Wheels are extremely hard and durable. This allows them to give better performance and greater longevity over regular abrasives.

When your wheel lasts longer you will see reduced costs for fixtures and tooling. This opens up your budget up to investing in more machines.

You will notice that the wear and cuts on your materials will be even. Because the abrasiveness of the wheel is so strong, it doesn`t develop uneven worn away spots as quickly as regular abrasive wheels.

So the output from your production will be consistent. So your manufacturing efforts will produce reliable and consistent results.

It can be tough to justify the upfront increased costs of superabrasive wheels. But the durability and quality of their production output make them well worth it.

But you`ll quickly realize that your productivity has increased by using superabrasives. You will have more parts processed per wheel and fewer wheel changes.

Kemei produces both conventional grinding wheel and super abrasive grinding wheels, such as white aluminum grinding wheel, pink wheel ,green silicon wheel, diamond grinding wheel and CBN grinding wheels.
