Design

Fully automatic single-station machine with integrated high-performance drill unit. Freely programmable control with fault diagnosis and status display. Clamping of the work-pice to the balancing machine by precision adapters with pneumatic unclamping mechanism. Support device located under the work-piece during drilling, to compensate for the drill force. Unbalance evaluation, correction calculation and correction control through PC controlled measuring unit. Manual loading or optional loading for the machine by a hand-operated system and the corresponding conveying technique.

Design

Range of application

Measurement and correction of single-plane unbalance in discshaped rotors with and without shafts, such as flywheels, TMF (twin mass flywheels), brake-drums, gears, clutch-plates, compensation shafts, blowers, etc.

Flexible integration into production line and simple change over of the machine to different rotor types by exchange of work-piece interface adapter and selection of rotor type file.
Unbalance correction by axial or radial drilling in polar or component format. If the initial unbalance is larger than can be corrected by one drilling action, multiple holes can be drilled.

Other unbalance correction methods such as milling, welding, riveting or punching can be integrated into the machine on request. The correction units are flexible and are adapted to the work-piece.

Vertically arranged milling unit for axial unbalance correction on a differential housing. Unbalance correction is made in components.
Horizontally arranged milling unit for radial unbalance correction on an articulated flange. If the unbalance cannot be removed in a single milling operation, correction is made in multiple components as required.
Interfacing with roller conveyors. Flywheels are separated one-by-one and then loaded into the machine by means of a handling system. At the same time, balanced flywheels are unloaded. The double spindle drilling head increases the amount of material removed and reduces the cycle time. Drilling depth and adjustment of the drilling unit to the specific correction radius are controlled by the measuring instrument.
Vertically arranged double spindle drilling unit for axial unbalance correction on guide wheels. Drilling forces are compensated by a power clamping system.
Multiple-station balancing machine with diagonally arranged welding system for unbalance correction on turbines. Correction is made with the help of fixed weights dispensed by a shaking system and supplied one-by-one to the welding electrode: The angle between the two weights is varied depending on the unbalance.
