Balancing of rotating tools and tool systems

ISO 16084:2017 specifies requirements and provides calculations for the permissible static and dynamic residual unbalances of rotating single tools and tool systems. It is based on the guideline that unbalance related centrifugal forces induced by the rotational speed do not harm the spindle bearings, as well as prevent unbalance related impairments of machining processes, tool life and work piece quality.

NOTE 1 Tools and tool systems covered by ISO 16084:2017 are, for example, those with hollow taper interfaces (HSK) according to ISO 12164-1 and ISO 12164-2, modular taper interface with ball track system according to the ISO 26622 series polygonal taper interface according to the ISO 26623 series, taper 7/24 according to ISO 7388-1, ISO 7388-2, ISO 9270-1 and ISO 9270-2 related to their individual operating speed.

Modular tool systems are another important and complex issue of ISO 16084:2017. Calculations and process descriptions for balancing these components and the assembled tool systems are included.

ISO 16084:2017 is putting an important focus on the possible clamping dislocations of tool shanks and their effects on the balancing procedure. These dislocations can occur be
