Balance Making Principle

The principle of dynamic balance of rotary tool is similar to that of general rotary parts. First , to measure the unbalanced weight and position, then the balance can be achieved after the eccentric weight is removed or the counterweight is adjusted. After the dynamic balance setting, the tool is smooth, the precision is more stable, the vibration is small, the work speed is higher. It can reach 10000-50000RPM.
