Causes of Generating Cracks in Diamond Grinding Wheel and Methods to Improve

The situation that it generates cracks in the diamond grinding wheels actually rarely happens if done properly. However, many people do not pay attention to the methods when using them. They think diamond grinding wheel will not break down, which is totally wrong.

The causes of generating cracks in the Diamond Grinding Wheel:

I. When diamond grinding wheels bear uneven loading and always give a hard push at the same point, the stress is not uniform. If it has been using for a long time, it will cause more severe wear in part of the position, and other places are still relatively intact. Therefore, the cracks are generated because of the extrusion caused by grinding.

II. The unevenly heated of diamond grinding wheels actually is also an important factor. We all know if the metal objects are in the heating and cooling for a long time, it will lead to be more brittle, and if you have been using it for too long time and with too much heat, it will produce cracks naturally when cooling them.

On the whole, if you want to make diamond grinding wheel generate cracks as less as possible, please try to make sure the whole grinding wheel is an average workload. The following is about the means of processing:

I. The greater feeding of grinding wheel, the deeper the residual stress in depth of the existence.

II. The residual stress on the surface as the tensile stress in the direction of grinding, and can also be in the form of pressure acting on the grinding direction of vertical direction. The deeper, the less the internal stress will be sharply reduced.

III. When acting on the grinding direction and vertical direction, it becomes into compressive stress at first and then suddenly becomes the tensile stress in the same direction. When the peak is gradually reduced, it will ultimately become small compressive stress.
