Balance Standards New Balancing Standard ISO 16084 – We Can Apply It
ISO 1940 •The generally-known balancing standard ISO 1940 promises simple and fast tolerance measurement. •Required data is: grade g, rotational speed of the tool holder and the weight. •Partial values not suitable for practical use. •Does not take into account the interface rigidness, measurement error of the machine, etc. Example HSK 40 tool holder, permissible residual unbalance .29 gmm > corresponds to .0145g (14 milligram). Such values are easy to achieve in theoretical terms, but unfortunately not in practice, because the worker has to work to 14 milligram accurate drilling. ISO 16084 New adapted balancing standard ISO 16084 for high-speed tool holders takes more variables into account for the calculation. •Stiffness interface parameters (bearing load, bearing distance, inaccuracy of shank, etc.) •Mass center of gravity •Consideration of measurement errors of own balancing machine and customer‘s machine •Decision whether static or dynamic balancing is necessary •Provides unbalance values for each plane during dynamic balancing Example HSK 40 tool holder, permissible residual unbalance, 1.88 gmm (with 15% safety) - Corresponds to a material removal accuracy of "only" .094g customer tolerance >2.54 gmm. - Tool holder may be statically balanced. Drill to milligram accuracy.
