Universal solution for medium-size rotors

Special equipment model 97V50 – vertical balancing machine for single-plane rotors weighing up to 50 kg. Can be used in repair shops and production plants with different product series.

It is possible to balance such parts on the machine:
  • Couplings of all types.
  • Pump impellers.
  • Automotive brake discs.
  • Impellers of gas compressor and aviation turbines.
  • Milk separators.
  • Brake drums.
  • Tooling for metalworking and woodworking.
  • Pulleys, flywheels, gears, blade fans, any part of the “disk-shaped” type.

The 97V50 has a rigid monolithic housing with an integrated preresonant vibration pylon on which the spindle assembly and electric drive are mounted. The spindle assembly has a tapered fit to achieve high alignment of the tooling with the rotary axis without the need for an indicator stand when adjusting.

 

The control is carried out through the control panel placed on the extendable stand attached to the housing. The control cabinet contains a frequency converter for smooth regulation of the electric drive and protection of electrical equipment. There is also a balancing system in the control cabinet.

There are two off-the-shelf options for selecting a balancing system: PB-02M (microprocessor-based system) and PAK-V (computer-based system with touch screen). It is also possible to make a special system according to the customer’s request.

A standard spindle with a tapered bore is used to mount a mandrel and attach a balancing part by means of a clamping bolt. This design is ideal for one-off and overhaul production with small batch balancing of various parts. For high production efficiency, the machine can be equipped with a hydraulically or pneumatically operated collet clamping device. Re-positioning a part on a machine with this modification takes approximately 3 seconds. The collet clamp can be controlled by a control panel or a foot pedal.

The PAK-1V unbalance measuring unit is a 2-plane measuring balancing system for balancing disc-type rotors on vertical balancing machines. It can perform static (single-plane) balancing in dynamic mode on a two-plane balancing machine.

Based on an industrial fanless computer with a touchscreen and a multi-channel measuring unit, the system ensures reliability and a long service life, even under intensive use. The PAK-1V utilizes a universal measuring path and modern component base, allowing for equally high accuracy when working with all types of rotors.

Its intuitive interface, self-calibration capability, and automation of key operations make the complex a convenient tool for both experienced specialists and novice beginners.

Useful features for vertical balancing
  • Takes into account the influence of the eccentricity of the balancing mandrel when measuring imbalance.
  • Distributing unbalance across design points makes it easier to balance parts with limited correction points. Examples of such parts are paddle fans, slot drums or baskets with turrets to attach correction weights.
  • Unbalance can be converted into hole depth and number of holes.
  • Unbalance distribution along the rotor axis into several correction planes

Your questions — our technical solutions

The 97V50 model is designed for the mid-weight range (up to 50 kg). It is ideal for parts that require high inertial stability during measurement.

Main applications:

  • Pulleys.
  • Flywheels.
  • Clutch components.
  • Fan impellers.
  • Brake discs and drums.
  • Pump impellers.
  • Cutting tools.

Yes, the machine can be equipped with a powerful vertical or horizontal drilling module.

For parts weighing up to 50 kg, significant material removal is often required; therefore, the 97V50 uses a reinforced drilling unit and features fine-tuning of the drill feed.

A milling module can also be installed if drilling correction is not permitted by technical specifications.

Suitable for small-batch production. Thanks to its high measurement speed and optional accessories, this model is ideal for workshops with low production volumes.

The following are used to secure parts:

  • Collet chuck: for the fastest possible setup in batch production.
  • Specialized adapters (mandrel): ensure high repeatability of results.

The machine is highly flexible and can be quickly configured for a different part. In most cases, standard cylindrical or expanding mandrels are used.

Features of setup:

  • Simplicity: The spindle design allows for tooling changes in a matter of minutes.
  • Versatility: If you have a wide range of parts, retooling will not become a bottleneck in production—the operator simply needs to change the adapter and reconfigure the measuring module for a different rotor.

Yes, despite its vertical design, the machine’s measuring system supports balancing in both a single (static) and two (dynamic) planes.

This is critically important for components where the disc’s width is comparable to its diameter, as it allows for the elimination of not only force imbalance but also torque imbalance.
