Tool holder balancing machine Hofmann Mess und Auswuchttechnik

Profi Tool Balancers PTB 7.2 and PTB 21.2 are solutions from Hofmann for balancing of tools or tool holders with standard conical spindle interfaces (SK, HSK, Capto etc.). The tools are precision-clamped in the spindle of the vertical hard-bearing (force measuring) balancing machines using suitable adapters. The available unbalance measuring systems convert the measured unbalance into all common practical units for unbalance compensation in one or two planes. In addition the unbalance measuring system MC 10 of the PTB 31.2 supports calculation of the permissible residual unbalance according to DIN 69888.

* Features
o Precision spindle for highest accuracy of measurement and repeatability
o Standard high-precision chucks for conical spindle interfaces (SK, HSK, Capto etc.)
o Hard-bearing (force measuring) balancing machine with permanent calibration
o Measuring system supports all common methods of unbalance measuring system
o Line laser module for precise marking of the correction angle position
o Calculation of residual unbalance according to DIN 69888 (option MC 10 PTB)

* Applications
o Balancing of tools and tool holders
o Balancing in tool holder manufacturing
o Balancing in tool maintenance shop
o Balancing of tools per DIN 69888
o Balancing of rotors without their own shaft journal , e.g. grinding wheels, blower wheels etc.
