Balancing machine 9A710 is a universal equipment of resonance type designed for high-precision balancing of parts weighing up to 3 kg.

For 20 years of production the design of the machine has not changed, which indicates the reliability of each node. The equipment is popular in workshops for repair of power tools, household appliances and at production facilities producing products with small rotors or electric motors.

The main feature of the machine is its accuracy of unbalance detection (0.4 gmm/kg, on special order – 0.1 gmm/kg), as well as its high versatility. The machine can be used to balance a rotor of any design as long as the dimensions do not exceed the permissible values. The equipment has a horizontal axis of rotation, which allows balancing not only inter-supported rotors, but also cantilever parts, most of the mass of which is concentrated on one side. Also, by using balancing mandrels, you can work with single plane “disk” type parts that do not have their own journals for mounting.

Conclusion: The machine can be used to balance rotors of small motors and generators, shafts of various mechanisms, impeller fans, impellers of pumps and blowers, as well as precision machine tools and rotating elements of drives.

The machine design provides high versatility: monolithic housing bed, movable narrow legs with 4 mm prisms and a special belt drive, most of which is in the housing bed, for optimum utilization of the working space. This makes it possible to balance workpieces with journals up to 4 mm apart.

The machine is also equipped with a separate electrical cabinet, including a control panel and frequency converter for smooth adjustment of the rotational speed of the parts during balancing, as well as reliable protection of the electrical components and systems of the machine. A remote foot pedal is also provided to control the drive for easy setup.

A measurement cycle of 25 seconds ensures high machine performance;
The unbalance reduction factor is 95%, which means that you do not even need 5 measurement cycles to achieve the desired results;
The belt drive has a micro-adjustment mechanism that allows you to precisely set the belt tensioning force and eliminate the occurrence of errors associated with the change of rigidity of the system “support – workpiece – belt – drive”;
The belt drive has a locking device that allows to hold the drive at the moment of part re-installation;
The machine is not demanding for maintenance, so there are no additional costs. All consumables are freely available and can be easily replaced;
Open working area allows you to work with oversized parts and makes the changeover easy and comfortable, which affects the speed of the operation;

Reversible rotation function, which allows efficient work with rotors whose design determines their direction of rotation, e.g. due to their high aerodynamic resistance;
Unbalance decomposition into design-determined unbalance points, which makes it easier to balance rotors with design-determined unbalance correction points, e.g. bladed fans, planers with blade slots or magnetic rotors with unbalance correction bosses on the end.

Balancing systems common features

The balancing system is adjusted using the “three starts” method. This allows the machine to always have a high level of sensitivity, since the equipment is calibrated with each new setup on the rotor.

In like manner, both balancing systems have intuitive controls. As well as well-thought-out interface with many tips and diagrams, simplifying the perception of information, allows you to quickly master the control of the machine and get started.

Balancing systems operate in “real time” mode, so that calculations of signals from machine sensors are displayed on the screen every second. It allows you to track the behavior of the imbalance when changing the balancing conditions, making the data analysis process much easier.

Furthermore, the equipment always has high sensitivity since the machine is calibrated every time a new setting is made.

We provide a 12-month warranty on all machines. Or an extended warranty of up to 36 months when conducting maintenance with the manufacturer.

Balancing system PB-02М features

PB-02M is a unique balancing system, the main advantages of which are efficiency and reliability. The microprocessor-based system is designed in every detail from the composition and architecture of electrical components and membrane control panel with liquid-crystal protected screen to the intuitive software that allows a person without training to master the control in 3 hours.

The balancing system has been developed specifically for trouble-free operation in harsh industrial environments. The system is universal and can be used for all balancing equipment. Machines equipped with this system work without problems in dusty or humid environments. Low temperatures (down to -2°C) are also no obstacle to obtaining correct and accurate measurement results.

Functions and features

Calibration of the machine by the operator himself (takes no more than 2 minutes), which ensures a constant high accuracy of measurements and saves money and time for calling a specialist;
Real-time graphical and digital display of information improves the quality of analysis and simplifies the search for factors affecting the quality of balancing;
Calculation of “allowable unbalance” and “weights of control weights” will save you from complicated mathematical calculations;
Unbalance vector averaging will improve the quality of unbalance detection and reduce the balancing cycle time.

Graphic method of unbalance vector display.
Display of balancing in real time: if there is any defect of a rotor or a hindrance, you see it as fluctuation of measurement result at once.

Non-volatile memory:
- 20 pre-adjustments of rotors;
- 100 results of measurements;
- 1000 balancing reports.

Possibility of decomposition of the correcting weights on structurally conditioned anchorage points (buckets, blades, slots).
Control of rotation speed.
Creation of reports on the carried-out balancing for further viewing or analysis.
