  • FAQ: Why should I invest in a balancing machine?

    An unbalance causes centrifugal forces. The centrifugal forces increase squared to the spindle speed. Older machines have spindle speeds of about 2,000 rpm. Even at 10,000 rpm the unbalance in the same exact tool holder causes a centrifugal force that is 25 times higher. The centrifugal force stresses the spindle bearings.
