wheel how to pay attention to the maximum speed

Grinding may cause serious injury, from the prone negligence: the ultra-high-speed operation wheel.
When the wheel to the rated maximum speed much higher than the speed of operation, probably in operation  abrasive sanding belt within minutes broken,
And if the wheel speed of operation is slightly higher than its rated speed a little, there may be dangerous.
This is not very serious overspeed condition may cause wheel damage, and the damage they may cause further
Fragmentation occurs after use. For example, in a 7-inch angle grinder to 7,700 r / min to enhance the speed of
9 inches in diameter, 27 type maximum rated speed of 6,600 r / min grinding wheel, grinding wheel may cause cracks.
This may cause cracks occurred after fragmentation.
The following actions may result in overspeed condition:
Mounted on the grinder, such as "gun shaped" pneumatic grinder;
Directly mounted on the motor wheel;
In the wheel size incorrect wheel installed on the machine;
Without proper maintenance of grinding disc  the machine components, in particular pneumatic controller of the machine on the machine and the floor-connection mechanism;
Incorrect use of the gas source, the hydraulic source or power supply;
Using an improperly set machine speed.
Ultra-high-speed running wheel may cause wheel breakage. Icon wheel cracks on the ultra-high speed wheel generated when running,
It may lead to accidents.
Any such action will have a catastrophic situation that could cause serious injury or death.
State to run the risk of speeding from the centrifugal force. As a result of rotation, the centrifugal force in cutting and grinding disc  the rope
The end of the round weight for rotary motion prompted the weight force of the rope taut. When the wheel's rotation time,
The same force will cause the weight of the grinding wheel away from the rotation center of the pull.
The centrifugal force will increase with the speed proportional way to increase, but instead with the square of the speed increase,
This fact led to a dangerous existence. When the selected speed doubled, the centrifugal force will increase fourfold.
This effect means that relatively small changes in speed can cause a huge increase in power
