Correction methods

Profile milling:
Polar unbalance correction at the correct location, suitable for most applications.

Polar slot-milling:
The milling spindle with twin cutter is displaced axially to shift the effect of the milling operation to the polar direction of the unbalance.

Slot-milling:
A variable method for quasi-polar or component correction. High flexibility through employment of single or multiple cutters and adaptation of the component angle.

All correction methods can be used for armatures with inclined or straight stack slots. In addition to material removal by plunge milling, weight removal can be increased by controlled axial cutter advancing.
Design

Range of application

Measurement and correction of unbalance of armatures of various sizes. Application of the machine
in production lines for large rotor volumes.
Unbalance correction by milling into the stack (profile/slot milling) in one or two planes.

Design

Four-station machine with fully automatic sequence of operations. Station-to-station transfer and integration with peripheral equipment through integrated rotary transfer system.
Work-pieces can be delivered to the machine by conveyor belt or on pallets.
