Balancing Machine for Crankshafts 300 EBTK, 310 EBTK - Schenck India
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.
Design
Design
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.
