Special balancers
Produced by CIMAT Ltd.
Independently of the production of universal balancers, we also provide special balancers customized. Because some of them have been manufactured very frequently, they even gained their specific characteristics and names. The list of the respective balancers has been provided in the table below, whereas basic notes have been presented in the text given below.

Notes: CMT 47
tr The CMT 47 tr balancers for car turbo-compressors are applied in the first stage of car turbine regeneration. They serve the purpose of dynamic balancing of the rotors of all types of car turbo-compressors in two planes, after the rotors are removed from the housing of the turbo-compressors, at the approx. rotary speed of 3000 rev./min. CMT 48
tr The CMT 48 tr balancers are useful in the next stage of turbine regeneration, after the bearing rings and sealings are exchanged, and after it is assembled again in the housing of the turbo-compressor. The process of balancing performed by CMT 48 tr occurs simultaneously in two corrective planes at the rotary speed of about 40 000 rev./min. The performance conditions of the turbo-compressor are similar to those that occur in the internal combustion engine. CMT 48
TWIN Balancing machine CMT48 TWIN is practical and economic binding of the CMT48tr and CMT48ntr.
The balancers prepared for the large-scale manufacturing operate in the general management system. They are able to receive and send the data in the data transmission standard accepted by the client. They are able to read the barcodes for identifying of rotor.
CMT 25V2 WENT CMT 50V2 WENT / Balancers for car electric fans CMT WSV2 The balancers for car electric fans are destined for the mass production of these sub-assemblies. In connection with that, they are distinguished by the speed of their operation and special shapes. The time of the full measuring period is particularly short here. They enable convenient service at the low energetic cost of an employee. Balancers for rotors of the electric motors CMT 50H2 Elektra The specificity of this type of balancers consists in the fact that a special shape of the rotor is used in them, its circular symmetricalness, occurrence of an inlet, preparation of special places for the mass distribution such as, for instance, bolts or channels. The balancers are prepared for large-scale manufacturing and operate in the general plant management system. They are able to receive and send the data in the data transmission standard accepted by the client.
Balancers for railway wheel sets CMT 1500H2 KOLEJ Photos: 1 The balancers for railway wheel sets have the following construction characteristics:
The company manufactures balancers for two main destinations:
All the balancers for transmission shafts have the following characteristics:
In order to facilitate the service, they can be equipped with:
The software allows the balancing results to be read in the form of the length of the corrective plate. CMT 250WNSerwis CMT 250WN Balancers for paper rollers and rollers of belt conveyors CMT 500H3/Poligra The balancers for paper rollers and rollers for belt conveyors have the following construction details:
They are equipped with specific software:
Balancers for brakes back plates and brake drums Wyważarka CMT 25V1/Hamul They are carried out in three versions:
Half-automatic and automatic balancers are equipped with the technological ancillary equipment, which serves the purpose of correcting the mass distribution. We assemble milling machines or drillers, which operate in the digital control system. Apart from that, the machines may be coupled with the general plant control system. The balancers for brake back plates and brake drums have the following characteristics:
CMT 5V1/Frez They are equipped with a spindle and an end that serves the purpose of fastening both the shank cutters and the interlocking cutters. Balancers of tool holders and tools CMT 8V2 The balancers have been designed as the equipment of the processing centres. A vertical spindle with a universal flange that serves the purpose of fastening the holders of ISO or HSK types are built in them. An important feature of their construction are centering holders which are characterised with a very good repeatability of fastening of the balanced object. They are equipped with the necessary compensations of unbalancing caused by the non-centricity of fastening of the object in the holder, and the compensation of unbalancing of the holder. The location of the place that is to be corrected is shown by a laser ray. Balancers for circular saws for steel plants CMT 600T Photos: They have a rich technological ancillary equipment, which facilitates the fastening of the saw blade disk on the balancer and the correction of the weight by grinding of an appropriate groove. Owing to a great GD2 span of the saw blade disk, the balancers have a great starting torque. The servo drives enable the automatic positioning of the saw for grinding or milling. The holders on the spindle enable the application of the compensation of the fastening error. The respective activities related to fastening and disassembly of the disk are performed in the manual system, but they are supported pneumatically or by means of mechanical, electric drives.
1. The special balancers are sold together with mechanic covers and marked by the manufacturer with the CE sign.
We apply CMT48ntr balancer when we want to check whether additional dynamic phenomena will occur on the rotor at the rotary speeds approximating the rated speeds, especially in turbines of a small size. It can be a deflection of the "cold" wheel from the axis of vibration, for instance, as a consequence of bending the end of the axis under the influence of loading with the moment of the force. The process of balancing occurs in one corrective plane, on the "cold" side, at the rotary speed of up to 200 000 rev. min.
The performance conditions of the turbo-compressors are similar to those which occur in the internal combustion engine: the turbine rotor is driven with compressed air, and the bearing is supplied with oil whose pressure and temperature are the same as in the engine chamber.
On the two positions realizes tasks of the both balancers.

The balancers for fans are characterised with the following construction details:
vertical spindles are assembled in them
housings which decrease the forces coming from air flows
self-centering holders mounted in spindles
great starting torque at the prolonged start and braking
the results of balancing are presented in the form that is convenient for the applied balancing technologies: welding, drilling, placing of corrective plates.
CMT 100V2 WENT
The balancers which serve the purpose of balancing the electric fans with a rotor of a “roller” type, as for instance, the ones applied in the car heaters, have an additional utility software installed. They minimize the number of corrective plates fastened on the rotor. The results of the measurements of unbalance are presented in the form of the distribution of corrective plates with the appropriate weights, available sizes for the respective blades.
Most frequently, the machines operate in the automatic mode, except for the disassembly of the balanced rotor.
