    97V300 machine for balancing disc-shaped parts up to 300 kg

    The balancing machine model 97V300 has a vertical axis of rotation and is a universal pre-resonance type equipment. The machine is designed for balancing disc-shaped parts with a mass of up to 300 kg. Its high degree of versatility has made this model popular in repair shops with a wide range of products being balanced and its high output is very popular with serial manufacturers.

    Although the machine is suitable for balancing “disk type” parts Although the machine is suitable for balancing disc-type workpieces, it is also suitable for balancing workpieces with two measuring surfaces.

    The 97V300 can be equipped with a pneumatic or hydraulic collet clamping, which greatly increases productivity when balancing large batches of the same type of parts. The standard version of the machine has a conical seating of the spindle, which allows, with the help of balancing mandrels, to work with a large number of different parts.

    The equipment has a monolithic case and a preresonant support that allows to work with heavy rotors. Spindle unit machine has high-precision bearings and a unique design that ensures high accuracy of unbalance determination (0.4 g*mm / kg). In addition, the spindle assembly is equipped with an electromagnetic spindle lock for easy unbalance correction and readjustment.

    The machine is equipped with specially developed for this type of machine software PAK – VERT. The software supports the function of the tracking system providing control of the angular position of the spindle that allows you to instantly determine the position of the unbalance correction, as well as allows you to organize the function of automatic rotation of the part in a given angular position if necessary to adapt the equipment to work in an automatic production system in industries with mass production output.

    The balancing machine is controlled by a “control desk” located in a separate control cabinet. There is also an industrial computer with touch screen controlling the hardware-software complex PAK-VERT. If necessary, it is possible to order the manufacture of a unique balancing system with the characteristics and functions specified by the customer.

    • The machine is versatile because it can be easily adapted to any production and workpiece, it is easy to adjust and does not require unique skills or knowledge;
    • The vertical axis of the spindle solves the problem of bias on one side, as the entire weight of the part is evenly distributed, so there are no balancing errors;
    • The monolithic design of the machine frame and its vibration isolators prevents vibration losses during balancing, which results in high measuring quality and reliability;
    • The open working space allows for balancing parts with overall dimensions of up to 1500 mm and facilitates part installation;
    • Hardness of the balancing arbors and tapered contact surface of the spindle is 55-60 HRCe, which excludes the loss of the machine accuracy by the wear of the contact surfaces and provides the high accuracy during the whole period of the exploitation of the machine.

    Advantages of the PAC-VERT software and hardware complex:

    • Three-start self-calibration allows you to maintain high machine accuracy without the need for third-party specialists, saving you money and time. Calibration takes 1 minute and can be easily handled by the machine operator;
    • Static-momentum balancing separates imbalance in static and momentum components for successful balancing of “problematic” parts that are asymmetrical due to thermal deformations after welding operations or are out of balance after assembly;
    • Distribution of unbalance to constructionally determined points simplifies balancing of parts with constructionally limited unbalance correction positions, e.g. bladed fans, parts with grooves or bosses for unbalance correction;
    • Storage and printing of balancing results allows for monitoring of balancing operations to further improve the process or to resolve quality issues.

    • Rigid construction, markedly, allows to balance rotors with large initial unbalances.
    • Moreover, removable balancing equipment allows you to quickly re-equip the machine for parts with different mounting holes.
    • Jacks for smooth installation and removal of parts on the faceplate both ensure the protection of machine mechanisms from impacts, create convenience and safety in the process of work.
    • Class B rotor protective guard protects against contact with rotating parts.
    • Automatic turn function, as well as the spindle fixing mechanism at the unbalance elimination point allows you to quickly and accurately guide the disk to the place where unbalance is eliminated (drilling, milling).
    • Asynchronous variable-frequency electric drive allows infinitely variable speed control without stopping the motor, selection of optimal modes for balancing, as well as additional turn on the vertical balancing machine 97V300.
    Vertical Balancing Machine 97V300


    Digital system is based on an industrial fanless computer with both a touch screen and a measuring unit.

    Set-up mode by “triple start-ups” method with the use of calibration weights on the serial rotors with initial unbalance.

    The operator calibrates the machine, enabling to reach the maximum sensitivity of the machine, thus exempting from the duty to pay annual calibration fees.

    • Calculation of the balance tolerance values, are obviously, recorded in technical documentation for the balancing product.
    • In addition, value calculation of the correction test weights to simplify the tuning process for the balancing rotor.
    • Real-time balancing display, i.e. if there is any defect or a hindrance of a rotor, it’s visible immediately as fluctuation in measurement result.
    • View of unbalance value both in g, gmm, gsm and gmm / kg optionally.
    • Taking into account the eccentricity of the balancing mandrel.
    • Unbalance distribution on n-planes correction
    • Calculation of hole depth for correction of unbalance.
    • Possibility of decomposition of correcting weights into structurally conditioned anchoring points (blades, fans, slots).
    • Rotor balancing report creating and printing.
    • USB port for printer connection, USB-flash memory, port for connecting to local network as well as Ethernet network.
