Auswuchtmaschine für Turbolader-Verdichterräder
100 FBLS | 300 FBLS | 500 FBLS

Design
Two-station machine with measuring and correction station and fully automatic operating cycle. Vertical balancing unit on a vibration-optimized machine frame, type-dependent, exchangeable precision air-bearing support for the compressor rotor, drive by a special drive plate with air jet adapted to the rotor diameter.

Measured data processing by measuring unit CAB 750.

Correction station with NC-controlled milling unit for unbalance correction by polar milling at the hub and rear side of the compressor rotor.

Gantry loading system for linking the stations and connection to an in-feed and out-feed conveyor.

Range of application
Measurement and correction of dynamic unbalance in machined turbocharger compressor rotors, Use of the machine in mid- to large-volume production. Fully automatic unbalance measurement and correction through polar milling in two planes and with up to two correction steps. Loading and unloading by gantry loader.

Sequence of operations

• The work-piece is taken from the transfer conveyor and loaded into the machine
• Automatic measuring run, brake to zero rpm
• Remove the rotor from the measuring station and load it into the correction station
• Clamp, index to the correction position for the 1st plane, advance the milling cutter to the milling position and control the milling cut. If the unbalance is large the cutter is additionally turned to increase the amount of material removed
• Index and move the milling device to the correction position for 2nd plane, repeat the milling process and unclamp
• Transfer the rotor to the measuring station and start the check run
• Remove the work-piece and unload it to the out-feed conveyor

Measuring station with air bearings for highest measuring accuracy.

Unbalance correction at the hub and at the rear of the rotor is achieved by means of a numerically controlled milling unit.

The linear gantry loader system loads the machine stations and links it with the transfer conveyors of the production line.
