• Universally applicable
• High balancing accuracy
• Easy to upgrade through modular construction and a wide range of accessories
• Hard-bearing principle ensures quick change-over from one workpiece to the next
• CAB 700 or CAB 920 measuring instrumentation with extensive operator prompting
• Full range of safety equipment for all protection classes

Range of application

Universal balancing machines series HM are conceived for highly precise balancing of a wide spectrum of rotors. They are suitable for balancing cylindrical rotors with integral shaft journals and for balancing disc shaped rotors on balancing arbors.

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

Their 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, braking. 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 correction of 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
