Method for adjusting the dynamic balance of grinding wheels
static balance adjustment :
Use the static balance frame to detect the mass distribution of the grinding wheel, and adjust the balance block to make the grinding wheel stationary at any position
dynamic balance adjustment :
Use a dynamic balancing instrument to detect the vibration data of the grinding wheel during rotation. Adjust the position of the balancing block as prompted by the instrument until the residual unbalance meets the standard
Steps for using dynamic balancing instruments
Install sensors : Attach the vibration sensor near the grinding wheel and align the rotational speed sensor with the reflective paper.
Start detection : Run the grinding wheel, and the instrument automatically measures the unbalance and phase.
Adjust the balance block : Move the balance block to the specified Angle as prompted, and repeat the detection until the vibration value is qualified
The risk of high-speed rotation of unbalanced grinding wheels
Decline in processing quality : vibration causes vibration marks on the workpiece surface and dimensional accuracy deviations
Equipment damage : The main shaft bearing wears out rapidly, and the grinding wheel may burst due to centrifugal force
Security threat : Flying debris may cause injury to personnel
The method for determining whether a grinding wheel needs dynamic balancing
observation method :
Check the surface of the grinding wheel for cracks, notches or uneven local wear
auscultation method :
Abnormal noises (such as a "buzzing" sound) may indicate internal cracks or loosening
vibration detection :
If there is obvious shaking or increased grinding vibration during idling, the machine should be stopped immediately for inspection
performance testing :
When grinding efficiency decreases, sparks are abnormal or the surface quality of the workpiece deteriorates, dynamic balancing is required
