Horizontal balancing machine for Small rotors and complete assemblies
Complete workplace designed for standing or seated operator
Highest balancing accuracy through super-critical support pedestals and digital meaurement processing
Short change-over times, simple and safe operation
Modular design for various applications
Product Specification
Range of application
Universal balancing machinery R1B is especially suitable for very small work-pieces such as small armatrues, miniature ventilators and complete assemblies, when high balancing tolerances at high speed must be achieved. They are used in small production lots as well as research and development applications.
They can be used at varying locations and the change-over for other rotor types is possible in a short time.
Design
Displacement measuring, horizontal balancing machinery of tabletop design for standing or seated opertor with semi or fully automatic operating sequence.
If the machine is to be used for assemblies, the two support pedestals are connected by a frame. An adapter and clamping arrangement is mounted onto this frame for supporting the rotors.
The drive can be by tangential, under slung, over slung, compressed air or, in case of complete assemblies, by an integrated supply for self-drive.
