In the previous article, we discussed the cone of inner round grinding.
After solving the problem of conical, the most common internal round grinding problem is roundness. It is crucial to maintain the quality of the components in the specified beach.
The circularity, which is generally called exhaustiveness, means that the real shape of the elements on the parts of the part maintains the distance between the center. The tolerance to the roundness is the maximum volume authorized by the real circle towards the ideal circle on the same surface.
Even if the round pieces are all round, it will not be completely round. Some are oval, some are in the shape of leaves and some are other “non -circular” forms.
What interests us is: during the grinding process, if parts are involved in the specified roundness. What is the most likely solution?
Solution01
Add no spark grinding:
The circular problem is generally due to the deformation or force which must be released during the grinding process. The simple solution is that the oil tanker does not come back, add a spark grinding to ensure that any deformation and strength are released.
Solution02
Add the speed of the part:
Sometimes the addition of clean parts can solve the circular problem. In particular the circular problem caused by harmonics to eliminate the corresponding harmonics by modifying the speed of the part. The acceleration of speed or reduction of food generally reduces grinding force, deformation and vibrations.
Solution03
The sharp sand wheel:
The grinding efficiency of sharp sand wheels is higher, less force is necessary and less vibrations are generated. Therefore, the sharp sand wheel can produce more round parts. The optimized cutting parameters are the basic means to ensure a sharp sand wheel.
Solution04
Reduce the liquid cooling pressure:
If the long part is crushed, the coolant must be increased, which is conducive to cooling and the suppression of balance. However, in the narrow space of the long cylindrical body, the high pressure coolant will turn the wheels to divert, causing the part of the parts after grinding. In these cases, reducing the cooling liquid pressure can solve the roundness problem.
