1. Wear problem

Any grinding wheel has its use of wear requirements, wear to the extent of the need to replace the new wheel. Can not be used in order to save materials, super wear requirements, this is a very unsafe violation. It is generally stipulated that when the grinding wheel is worn to a diameter 10mm larger than the chuck diameter, it should be replaced with a new grinding wheel.

2, the use of the issue.

The new grinding wheel brought out from the warehouse is not sure that it is a qualified grinding wheel, and even the new grinding wheel bought from the manufacturer is not sure that it is a qualified grinding wheel. Any grinding wheel has its use period, in the use period, it is a qualified grinding wheel. The regulations stipulate that "the grinding wheel should be used within the service life, and the resin and rubber binder grinding wheel should be subjected to rotary test after one year of storage, and those who are qualified can only be used".

3. The problem of texture

In the process of use, if the grinding wheel is found to have local cracks, it should be stopped immediately and replaced with a new grinding wheel, so as not to cause the grinding wheel to break and hurt people.

Note:

1. Side grinding problem

In the daily use of the grinding machine, we can often find that some operators do not divide the type of grinding machine, regardless of the type of grinding wheel, randomly use the side of the grinding wheel for grinding, which is a serious violation of the safety operation regulations of the illegal operation behavior. According to the rules with the circumferential surface as the working surface of the grinding wheel should not be used side grinding, the radial strength of the grinding wheel is large, the axial strength is very small, the operator force is too large will cause the grinding wheel broken, and even hurt people, in the actual use of the process should be prohibited.

2. Positive operation problems

In daily use, many operators are always used to operating on the grinding wheel because they can be used in this direction. In fact, this kind of behavior should be particularly prohibited in the operation of the grinding wheel. According to the operating procedures, when using the grinder to grind the workpiece, the operator should stand on the side of the grinding wheel and not operate on the front of the grinding wheel, so as to avoid the grinding wheel flying out or the grinding wheel breaking out and hurting people.

3. Force operation problem

In the use of grinding machine, some operators, especially young operators, in order to seek the speed of grinding, too much force, this is a very unsafe operation behavior. The flat body of any grinding wheel has strength, which is likely to cause the grinding wheel to break, or even fly out to hurt people, which is also a prohibited behavior.

4. Joint operation problem

In the actual daily operation, there are also such situations. Some people share a grinder to operate at the same time in order to catch up with production tasks and work time. This is a serious illegal operation and should be strictly prohibited. When a grinder is not enough, it can be solved by adding a grinder, and it is never allowed to share a grinder at the same time.
