HM
Maximum precision and flexibility for many areas of application: The universal balancing machines of the HM series are ideal for balancing horizontally mounted rotors. HM balancing machines from Schenck are suitable for smaller businesses and workshops as well as for manufacturers of larger quantities.
The all-rounders among balancing machines.
Modular system for maximum flexibility Adapt your balancing machine to your needs – not the other way around. Whether for single rotors or small series, the modular system and versatile accessories make HM extremely flexible. This means you benefit in the long term from an investment that pays off.
Balancing with variable drives With HM universal balancing machines, you can combine different drives on one machine: The wrap-around belt drive (BU) is characterized by smooth running and versatile application possibilities, while the drive shaft drive (U) offers high drive power.

Special features
-
Schenck universal balancing machines of the HM series are ideal for single rotors and small series:
- Easy to operate, as no calibration runs are necessary thanks to the force-measuring principle.
- Balancing possible in two planes or separately according to static imbalance/moment imbalance.
- Storage of rotors on original or auxiliary shafts, on support rollers or in slide bearings/with mounted roller bearings.
- Angle adjustment display for belt drive
- Automatic measuring cycle with continuously adjustable values for start-up, measuring and braking times.
Expandable with numerous additional modules, e.g. for mass balancing.

Protective device
-
The hazard posed by the rotor is decisive when choosing your protective device. Take into account the balancing speed, balancing method, and maximum possible impact energy. Protective devices for balancing machines are divided into five safety classes (0, A, B, C, D) according to ISO 21940-23. Class B or C protective devices are mainly required for HM balancing machines.
Select safety class B if there is a risk of injury:
- when touching the rotor,
- originating from parts of the drive
Select safety class C if it cannot be ruled out with certainty that parts may detach from the rotor.
We calculate the penetration potential for you based on the size, shape, hardness, and tangential velocity of a flying part and configure your protective device on this basis.
