Balance:
The balance need tobe inspected after the Abrasive wheels installed onto the flange. The good balance will increase the grinding result, but also reduce the shaking degree during working.
In addition, the good balance is also related to the following as below
A. reduce the consumption for abrasive wheels
B. Improve the geometric accuracy of the workpiece.
C. Reduce the roughness of the workpiece’s surface,
D. Reduce the burning of the workpiece.
E. Reduce the shaking of the abrasive wheels.
Then how to inspect the balance?
1. Knocking the abrasive wheels and listen to the sound.
2. Inspected by the flange: Checking the flatness of flange by ruler, and also could measure by dial gauge. The required flatness of flange is less than 0.05mm.
3. Install the abrasive wheels and tighten the nuts.
4. Adjusting the position of balance block to make the abrasive wheel to be in static when rotate in each position on the balance frame.
The size precision
The precision including the tolerance of diameter, internal diameter, the flatness difference of the two side, the verticality between the inner hole and two planes and so on.
If the size of inner hole is too big, then the abrasive wheel will not fit the flange very well. Then the grinding result will be affected.
If the inner hole and two planes are not vertically, the abrasive wheels will shake during working.
The surfance
The surface of abrasive wheel will bring the first impression to the buyer. We thought the abrasive wheels are industrial product, so the surface seems not very important.
But now, the surface have been one of most important factors to judge the quality of abrasive wheels.
