Reasons and Disadvantages of Grinding Wheel Unbalance

Grinding wheels are inhomogeneous objects, and when running, its center of mass and rotation axis center misalignment will cause vibration.

The reasons of grinding wheel unbalance mainly include:

A, Inner quality uniformity (uneven density)

a. Uneven mixed material and forming material.

b. Different firing conditions, contraction and reaction result in uneven density.

c. When forming, there is geometric deviation that result in uneven pressure everywhere. After finishing, The geometric accuracy is great but the density is still uneven.

B, The geometry precision (shape deviation)

a. The two ends are not parallel.

b. The outer and inner diameters of grinding wheel are different.

The disadvantages of grinding wheel imbalance:

A. It will affect the strength of grinding wheel spindle and increase the fatigue stress.

B. It will cause abnormal wear and tear of bearings.

C. It will cause grinding wheel vibration and decline of machining precision.

D. The grinding stress increases, and grinding wheel is easy to fracture.

E. Abnormal and uneven wear.
