Advantages

Minimum achievable residual unbalance: 0.3 g*mm/kg.
Unbalance reduction of up to 95% in a single run.
Highest measurement linearity across all speed ranges and unbalance levels.
An excellent, time-tested design refined over years of manufacturing, incorporating extensive operational experience across all industries and requiring minimal maintenance.
Unmatched versatility.
Quick and easy to master.
High-quality European industrial hardware — all handles. Virtually no tools needed for setup and operation.
Reliable, rigid, and vibration-damping bed with a non-slip coating.
Capability to balance rotors with a high initial unbalance.
An asynchronous frequency-controlled drive provides smooth, stepless speed variation and extensive options for selecting acceleration/deceleration modes.

Software

The "R-Bal V3.9" software, like the hardware, is developed by "PK Robals" LLC and is continuously improved. It features a simple, intuitive interface.

Software
Select the configuration of the rotor to be balanced based on the location of the correction planes relative to the supports (between supports, overhung, double overhung, to the left or right of supports). Perform dynamic balancing in multiple planes simultaneously or in a single plane. Convert imbalance from one set of planes to another, and from one correction radius to another. Perform manual or automatic rotation of the rotor to a required angle, with the current position displayed on the screen. Automatically generate a dynamic balancing report. Set the number of signal averages based on the required balancing accuracy.	Calculate the permissible imbalance level based on known values of rotor mass and maximum operating speed. Set tolerances in various units (gmm, gcm, g*mm/kg, mm/s, µm). Perform a rotor run-up (rotor spinning to align the axis). Measure the amplitude during coast-down (run-out). Use special correction modes (drilling, milling); the program calculates the number of holes required for imbalance correction. Monitor rotation speed with an accuracy of 0.1 RPM and alert the operator of deviations from the initially set parameters.

Launch and Dynamic Balancing Skills Training

When purchasing a balancing machine, we provide two types of commissioning services: an on-site visit by a commissioning engineer and remote machine startup.

A modern balancing machine is complex equipment, and in conditions of a shortage of qualified personnel, high-quality specialist training is especially important. Therefore, we provide assistance in personnel training. During the training of a balancing machine operator, skills for working with the machine and the principles of rotor dynamic balancing are transferred.

An excellent reference tool for the machine operator is the "Balance Guide: Multimedia Course for Preparation to Work on a Balancing Machine" program. The media course consists of a series of videos that provide a brief description of terms used in the balancing process, describe types of rotors, causes and types of imbalance, main correction methods, outline safety measures when working with the machine, principles of interaction with the machine components, and describe all the functions of the software that controls the balancing machine.
The program can be used to review knowledge acquired during the commissioning works.
