Mounting and Balancing Grinding Wheels
Now the grinding wheel is rotated by 90° and stopped. If weight no. 1 pulls downward, move the two other weights symmetrically away from no. 1. In case of the opposite, move the two other weights toward no. 1. Advantages. Cost-effective; Disadvantages. Grinding wheel must be removed from the machine for balancing
