Horizontal Balancing Machines
HM 2 - HM 20 | HM 3 - HM 30

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

HM bearing pedestals: Extremely slim but highly sturdy bearing pedestals guarantee high overall stiffness, high linearity and low damping. Use of the Schenck force-measuring principle, with the middle part of the bearing pedestal designed as a dynamometer. The sensors are arranged outside the force path and are therefore not affected by impacts.
