VTM Group 9D715US

9D715US crankshaft balancing machine is adapted for balancing crankshafts of various designs, including crankshafts of V6, V8, V10 and V12 engines, with balancing weights on the connecting rod pins:

- Balancing of crankshafts of any design
- Shaft weight up to 300kg
- Shaft length up to 1400mm
- Drilling module for unbalance correction

The machine design allows balancing crankshaft separately, as well as crankshaft complete with flywheel and clutch, which guarantees minimum unbalance during engine operation.

MACHINE HIGHLIGHTS
• Hard-bearing supports - safe operation with high initial unbalance at low speeds.
• Roller cassettes with large diameter spherical rollers and provide the required accuracy for balancing heavy shafts.
• Replaceable antifriction prismatic V-blocks allow balancing of crankshafts with low mass or with special bearing journals.
• Narrow support stands of the machine allow balancing of crankshafts with complex configuration and with “narrow” bearing journals. The 9D715US machine has a cassette width of 27 mm, which is the best in its class.
• For balancing V-shaped crankshafts, the machine can be equipped with counterweights (variable weight) to simulate the weight of connecting rods.
• A vertical drilling module mounted on its own guides allows unbalance in the crankshaft counterweights to be corrected directly on the machine.
• The frequency converter drive provides smooth acceleration and deceleration of the electric motor and infinitely variable speed control of the rotor.

MEASUREMENT AND CONTROL
• We make balancing easier - the main advantage of our balancing systems.
• The balancing process is displayed in real time and the unbalance behaviour of the rotor is monitored on the screen to achieve the best possible result.
• Measuring balancing system has additional necessary functions for crankshaft balancing:
- recalculates the unbalanced mass to the drilling depth, taking into account the drill diameter and the permissible drilling depth.
- It recalculates the unbalance on several correction planes, so that unbalance can be corrected in neighboring crankshaft counterweights.
