- 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
- Measuring instrument CAB 820, optional CAB 920 - the high end solution
- Full range of safety equipment for all protection classes
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
Design
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.
