BALANCING MACHINE 9K718M

Machine for balancing rotors weighing up to 8000 kg. Universal, soft-bearing, with self-aligning roller blocks.

Universal balancing machines of over-resonant type, with pendulum suspension and cylindrical rollers, with belt drive of rotor spin. In the 9K series, the VTM GROUP company presents a standard range of machines with a maximum weight of a balanced part of 300, 1000, 3000, 8000 kg. On machines of the 9K series, rotors are balanced with high requirements for residual unbalance, for the quality of the surface of the necks, and also for the quality of manufacture in general.

This led to the use of machine tools of the 9K series in a wide variety of industries: metallurgical, gas and petrochemical, energy, mechanical engineering, etc. The machines allow balancing intersupport and cantilever rotors, rotors on special mandrels, as well as in special equipment (frame). They can be equipped with a combined rotation drive for balancing various types of turbine rotors, rotors of special equipment.
