The surface in the grinding process were burned, are summed up and have several reasons:

1. The grinding wheel is too hard or too fine granularity organization dense;

2. Feeding is too large, cutting fluids are in short supply, heat condition;

3. The low speed, rotating speed of the grinding wheel too fast;

4. A vibration grinding wheel is too big, for grinding depth change constantly and burned;

5. The grinding wheel dressing or trim not bad;

6. Diamond sharp, grinding wheel dressing is bad;

7. When the coarse grinding burns is too deep, fine grinding allowance for and too small, no grinding away;

8. The clamping force or inadequate suction in grinding forces, the phenomenon of existing stalled.

So the surface in the grinding process how to know whether burn service? This is to regularly check out by pickling can.

After the pickling, in surface wet, immediately under the lamp in astigmatism visual examination, normal surface homogeneously dark gray. If software dot, present the clouds form dark spots, and condemn the entire perimeter; If the decarburization, revealed a gray or diablo color spotted; If grinding crack, the crack is cracked form, if burns, a surface grinding wheel is along the direction of diablo splash on processing, the second is to present lines or intermittent line shape.

As in the grinding process in the above burns phenomenon, must be timely analysis reasons, take effective measures to solve, put an end to batch burns.
