2, grinding pressure is too large.
3. Excessive lubricant on the workbench guide rail; causing the workbench to float.
4. The grinding wheel is poorly trimmed; the corners are not chamfered; the coolant is not used for dressing.
Ǘ┞èªå’ å‚» silly wood 1〠1, the workpiece itself is poor rigidity,
2. The dressing of the grinding wheel is not good; there are some bumps.
3. The crushed and detached sand on the grinding wheel and the iron scraps under the grinding of the workpiece are attached to the outer surface of the grinding wheel; for this purpose, the finished grinding wheel should be washed or rinsed with cooling water.
4. When the quarrel is repaired, the commutation speed of the workbench is unstable; the precision is not high; the trimming of the grinding wheel is slightly less.
5, the V-shaped guide rail is not good enough; when grinding, the grinding wheel is offset; only the edge of the grinding wheel and the touch of the work surface,
The main reason for the appearance of the brushing on the surface of the working surface is that the coarse abrasive grains fall off; the abrasive particles are formed between the workpiece and the grinding wheel. The detailed reason for the external appearance of the workpiece being roughened during grinding is:
1. The coarse abrasive grains and fine abrasive grains in the cooling liquid are not cleaned.
2, traces left over from rough grinding; not worn out during fine grinding,
The main reason for the fish scale-like appearance of fish scales is that the cutting edge of the grinding wheel is not sharp; the phenomenon of "squatting" occurs during grinding; the oscillation is large at this moment. The detailed reason for the appearance of fish scales on the surface of the workpiece is:
1. The diamond fastening frame is not strong; the diamond rocking or diamond quality is not good, not sharp,
2. The grinding wheel is not trimmed,
3. There are waste and oil on the surface of the grinding wheel.
4. The hardness of the grinding wheel is not uniform.
5, the grinding wheel becomes dull. The trimming is not sharp,
