Factors Affecting The Normal Use Of The Grinding Wheel
Jan 02, 2019

In order to give the grinding wheel the best grinding performance, what are the precautions in the process?

Wheel speed

The maximum working line speed is specified on the label of the grinding wheel. Before use, it must be confirmed whether the spindle speed of the machine tool is within the linear speed range of the grinding wheel. Sometimes it is not enough to check the motor speed of the machine, but also calculate the speed ratio of the belt pulley.

Some machine tools are stepped speed regulation, and operators should be careful not to mistake the speed to a speed higher than the line speed of the grinding wheel.

Normative operation

Operators sometimes do not follow the process requirements. For example, the amount of feed is specified to be 2 wires per time, and some operators have to increase the amount of feed to 5 wires per time in order to catch up with the output. In this way, the grinding wheel is difficult to work normally, the working object is easy to cause burns, and some burn surfaces do not show blue burn marks, but in fact the hardness of the working object has been lowered, which has a great influence on the quality of the working object.

Diamond dresser

The normal line of the diamond pen and the grinding wheel should have an angle of 15°. The diamond pen can rotate several faces to keep the sharpness for a long time. If the diamond pen is blunt, it will not be checked and replaced, and the grinding wheel is still being repaired. And knowing the quality of grinding is not good.

Grinding machine maintenance work

According to the safety maintenance requirements, the machine needs regular maintenance. If the maintenance work is not taken seriously in order to save expenses, the machine condition is not good, such as the spindle accuracy is degraded or the bearing is excessively worn, which will have a very adverse effect on the grinding.

Machining working object instability

Mainly manifested in the instability of the size margin, the heat treatment hardness fluctuations are large.

Is the cooling system reliable?

Sometimes the user will reflect scratches on the surface of the working object. In addition to the impure abrasive grain size, filtration of the cooling system is a key. If the filtration is not good, the metal chips will be recycled to the grinding area, causing scratches on the surface of the working object. In addition, whether the flow rate of the coolant is sufficient or not directly affects the grinding effect.

In addition, attention should be paid to the storage, handling and installation of the grinding wheel:

The storage of the grinding wheel should pay attention to ventilation and moisture, especially the resin grinding wheel and rubber grinding wheel, but also pay attention to the problem of aging. Generally, the storage period of the resin grinding wheel and the rubber grinding wheel cannot exceed 2 years.

During the handling, we sometimes see workers rolling large grinding wheels on the ground, so that they accidentally hit other objects and cause the grinding wheel to be cornerless. It is extremely dangerous for the grinding wheel to run at high speed without corners. Therefore, we must try our best to avoid irregular handling.

Care should also be taken during handling to ensure that the tightening of the nuts is performed diagonally, from loose to tight.
