• Universal machine concept
• Automatic unbalance measurement
• Precision positioning during correction
• Microprocessor-controlled measuring unit

Sequence of operations

• Load a crankshaft into the measuring station, manually or by lifting device
• Close the protective shroud. Automatic measuring run and display measured values.
• Open the protective shroud and move the crankshaft to the correction stand.
• Insert the crankshaft into positioning device and couple with angleencoder for optional indexing aid or with locking-pin device
• Drill correction holes one after another corresponding to the display
• Return the crankshaft to the measuring station. Automatic check run and display of residual unbalance.
• Remove the crankshaft. If the crankshaft is still out of tolerance proceed with a second step.

Two-station machine with separate measuring and correction stations. Measuring station with coupling-free roller-drive or hook drive for asymmetrical crankshafts.

Correction station with positioning equipment and electro-mechanical drilling equipment.

Range of application

Measurement and correction of unbalance in machined passengervehicle and light commercial- vehicle crankshafts. Use in small and mid-volume series production or as a repair balancing machine.

Unbalance correction by drilling into the counterweights in one or more steps at a separate drill stand (correction station). Manual handling of the work-pieces between measuring and drilling stations.
