Ultimate industrial balancing solution, specialized industrial applications
The machine has high accuracy (0,4 gmm \ kg). Accuracy is achieved due to the special design of the spindle and the rig of the machine, as well as a reliable balancing system, PAK-1, which has a high degree of noise immunity. Ease of control allows you to quickly learn how to work on the machine and get to work as soon as possible. When designing the machine, high demands were placed on the functionality and versatility of each node, this made it possible to install absolutely any driveshaft on the machine with a minimum of time.

The axial drive provides direct connection capability for the most challenging power generation rotor configurations including nuclear, thermal, and gas turbine assemblies.
The PAK-1 unbalance measuring unit represents the latest generation of measuring complexes for dynamic balancing, combining high precision, stability, and ease of use. It’s designed to tackle a wide range of rotor balancing tasks, from simple to the most complex, requiring precise measurements.
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-1 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 beginners.
Features of the PAK-1 System:
- High-precision dynamic balancing for rotors of any configuration.
- Industrial fanless PC with touchscreen and multi-channel measuring unit.
- Setup using trial runs with calibration weights on production rotors.
- Self-calibration by the operator, eliminating annual service adjustment costs.
- Calculation of permissible unbalance values, even without technical documentation.
- Determination of control weight mass to simplify setup for a specific rotor.
