Balance errors and balancing BALANCE ERRORS AND BALANCING Definition of balance error Rotational axis ≠ mass axis A balance error occurs when the rotational axis of a rotor part does not correspond to its mass axis. Rotational axis = mass axis Reasons for Balance Errors: uu Indexing seat for tool changer in SK and HSK uu Driving slots in SK and BT uu Driving slots in HSK- A, C, CE uu any kinds of flats on tool shanks uu Locking srews for tool shanks with flats uu Non-uniform pitch on cutting tools uu Collets and tightening nuts uu Production tolerances Unbalanced arbor Balance errors can be eliminated...

Balance errors and balancing 2 Example of a calculation: Shrinking Arbor HSK 63A: 50 08 A63 S Weight: 760 grams Taper radius: 31.5 mm Balance grade: G 6.3 at 20,000 rpm Note to illustration: ”S” = mass axis Calculation of remaining balance error in example above: By means of precision balancing, the remaining balancing error has been minimized to 0.072 g (in relation to the taper radius of the arbor of 31.5 mm). Your advantages – why this is such an important subject. Balancing, particularly in connection with high concentricity, prevents your spindle from damage, because it decreases the centrifugal...
