Spark erosion involves removing material from a conducting part and eroding it to give it the desired shapes and dimensions by means of electrical discharges. In the wire sparks erosion process an unwinding metal wire, under tension, is immersed in water or in another insulating liquid (dielectric) with the part to be worked. The current transmitted forms an electric arc which gives rise to precise, programmed degradation of a section of the part. The residues created by wearing of the part are removed by the water or dielectric liquid. STEEC carries out both spark erosion and fine wire micro spark erosion operations Wires spark erosion and machining Equipped with the latest wire spark erosion technologies, STEEC is able to carry high precision cutting with wires of standard sizes whose diameter may vary from 0.15 to 0.25 mm in all types of mechanical parts.

The usable cutting area is available in multiple sizes allowing to process small to extra-large fabrics rolls. The SM-332-TA reaches speeds of up to 90 m/min with an acceleration of 1G with a motion repeatability +/- 0,1 mm. The cutting area is sectioned to concentrate the vacuum power in specific areas. Pressure bar and side grippers for synchronized movement of the conveyor with the fabric. Motorized conveyor belt to maximize cutting accuracy on long lengths. The SM-332-TA can be equipped with an optional motorized unwind system for large rolls with automatic material alignment control and correction and a digital tension control system.
