Range of application

Universal balancing machines series HM enable precise balancing of a wide spectrum of rotors. They are suitable for cylindrical rotors having their own shaft journals and for balancing disc shaped rotors on balancing arbors.

Permanent calibration, ergonomic Design and a logical operating sequence facilitate operation.

A modular Design principle and a wide range of accessories make the machine highly flexible.

Schenck universal balancing machines series HM are a highly efficient investment, both for one-off rotors and for small batches.

Sequence of operations

Manually load work-piece on the bearing pedestals, close hold-down bearings and connect drive (belt drive or drive shaft).
Close protection device and start automatic measuring sequence:
Acceleration, determination and display of the unbalance on the measuring instrument, brake. The readout is retained on the measuring instrument even after the measuring run has ended.
Open protection device, manually correct unbalance (if required).
Check correction result (with measuring instrument displaying whether the tolerance has been achieved) and unload the rotor from the machine.

Special features

Easy to operate – hard-bearing principle eliminates the need for calibration runs
Provides for correction in two planes or separate according to static and couple unbalance
Rotors can be mounted on their original shafts or on mounting arbors, optionally with mounted anti-friction bearings
Angle indexing display in case of belt drive
Automatic measuring cycle with infinitely variable settings for acceleration, measuring and braking time
Upgradeable by many additional modules e.g. for mass correction
