Lapping machines for planes
The machines use the lapping technology, which allow additional treatment with very high quality parameters. In many cases this technology is the only one, which can be used for parts precise treatment, when they are made from strengthened steel, hard alloys and ceramics. The lapping treated surfaces' exploitation characteristics are usually higher than those, achieved through polishing, honing and superfinishing.

Abrasive blasters
These machines are used for parts surface treatment before electroplating treatment, painting, thermal piling and other treatments. This technology can be used also for natural mat surface after the thermally treated, rolled or cast parts are cleaned.

Filament electroerosion machine
The filament electroerosion machine is used for instrumental equipment production. This equipment include matrixs, punches, different kind of dies, tools and other equipment with complex configuration, made from strengthened steel and other difficult for treatment materials. The single parts treatment is effective also.
The parts are treated through cutting without physical contact between the tool and the treated part and no chips are left.
The equipment contain working machine, impulse generator, microprocessor system with processor unit and ionizied water unit.
An electrode in the form of molybdenum, copper, brass or tugsten filament is used as a cutting tool. The filament contact with the treated forgings and move perpendicular or on certain angle, following the desired trajectory. The cutting is done through impulse voltage supply between the electrode - tool and the electrode - treated part, which cause electric corrosion.
The electric current impulses with rectangular shape and frequency are generated from impulse generator. The treated parts roughness requirements and the specific work conditions define the electric current impulses' shape and frequency. The needed form is achieved through the part's movement on the X and Y axes.
Deionized water is supplied under pressure around the cutting line. The treated part might be set in a tank with the same water. The deionized water act as working medium as well as coolant, which also carry out the erosion products from the cutting zone.
The contour cutting programme and the whole working process are managed by microprocessor system, working in dialogue regime of from programme software device. All machine blocks functions are tested and checked on a regular short periods of time. The cutting line movement is managed by interface, included in the machine.
