Automatic Vertical Balancing Machines 150 SVM, 151 SVM, 350 SVM, 550 SVM - Schenck Bulgaria

  • Fully automatic operational sequence
  • Manual loading and unloading
  • Interfacing with production line is possible
  • Fully automatic unbalance correction by drilling, milling, welding or riveting
  • Analog or NC axis controlled correction
  • Digital measured data processing

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.
