Factors Influencing Normal Working of Grinding Wheel

In order to make grinding wheel present the best grinding performance, what are the matters needing attention in the process of using?

The speed of grinding wheel

The label of grinding wheel has the largest linear velocity for work, and operators must confirm whether the rotational speed of spindle is within the range of linear velocity of grinding wheel before using. Sometimes, it is not enough only to check the rotation speed of the motor of machine tools, and it also needs to calculate the speed of the belt pulley.

The standardization of the operation

Sometimes, operators do not operate according to the process requirements. For example, the feed quantity is 2 every time, but some operators make the feed quantity reach 5 at a time in order to catch the production, which makes grinding wheel hard to work and easy to cause some burns of the workpieces. Some burn surfaces do not show the blue burn marks, but actually the hardness of workpieces has been lowered down, which has a great influence on the quality of the workpiece.

The diamond dresser

The normal line needs 15 ° included angle between diamond pen with grinding wheel, and diamond pen can turn a few faces to keep sharp for a long time. If diamond pens become dull but people don't go to check and change, and still continue to dress grinding wheel with them, of course the grinding quality of grinding wheel will be not good.

The maintenance work of grinding machines

In accordance with the requirements for security maintenance, machine tools require regular maintenance. If people downplay the regular maintenance work in order to save money, which will make machine tools in bad condition, such as dropping accuracy of spindles or excessive wear of bearings, it will cause adverse effect on the grinding.

The instability of machined workpieces

The instability of machined workpieces is mainly displayed in unstable size and the fluctuation of heat treatment hardness is also large.

The reliability of the cooling system

Sometimes, users reflect that the workpiece surface has some scratchs. In addition to some abrasive particle sizes that are not pure, the filtering of cooling system is the key. If the filtering effect is not good, it will bring scrap metal back to the grinding area, which will cause the surface scratch. In addition, whether the coolant flow is sufficient also directly affects the grinding effect.
