The Military Aircraft Works No.4 in Warsaw have free production capacity on the CNC wire EDM machine type RA 90 manufactured by MITSUBISHI ELECTRIC.

The photos of the machine - on the TECHNOLOGIES sub-page

The CNC wire EDM machine allows the following operations:

• processing of items of max sizes 860 x 760 x 150 mm,
• cutting angle 150/100 mm of height,
• transfer x/y/z – 320 x 250 x 150 mm,
• max weight of an item – 300 kg,
• processing of items made of steel, aluminium, copper, copper alloys, and tungsten carbide.

The machine control system: 64 bit CNC – PC with RISC processor and WINDOWS operating system, simultaneous 4-axis control. Precision of processing – standard to 0,01 mm, in special conditions to 1 micron. Measurement cycle – with graphic support. Graphic simulation of the cutting path.
Examples of the processing possibilities:

• manufacturing of toothed wheels, rabbets, cams,
• cutting of untypical internal and external cruising shapes,
• processing with high tolerances of sizes.

Modern processing machine and many years of experience in manufacturing of the aviation spare-parts is our assurance of the highest quality of jobs executed by our company.
We are interested in establishing regular business relations.
