Shaft center axis is fixed by own bearings, high-precision balancing can be performed.
Rotor shafts of spindle, Turbine rotors of jet engine, etc.
Flexible rotor which is very difficult to balance can be easily balanced by multi-speed multi-plane balancing algorithm.
Before high speed field balancing of assembly, each rotating components should be balanced by this balancing machine, then peaks of resonances can be suppressed.
Conventional balancing planes is up to 2 planes.
However, in case performing 2-plane balancing of rotary part of high speed rotary machine, check structure and shape of rotary part and select proper No. of Correction plane. Otherwise, it may cause higher order vibration of flexural mode under high speed rotation.
Sigma’s horizontal balancing machine expands No. of Correction plane until 4 planes at maximum, selecting proper No. of Correction plane freely. So the above mentioned problem can be solved easily.
