Product Description

Product Overview

Slow wire EDM is a type of electrical discharge wire cutting that uses a continuously moving thin metal wire (called an electrode wire) as the electrode to remove metal from the workpiece through pulse spark discharge and cut it into shape. It is mainly used for machining workpieces with complex shapes and high precision requirements.

Precautions

■ Please store the electrode wire in a well-ventilated, cool, and dry place. Try to keep the temperature between 20°C and 25°C to prevent oxidation of the electrode wire.
■ If the electrode wire is stored for more than 6 months, problems with verticality may occur.
■ Tensile strength ≥ 980 N/mm², suitable for straight-line machining. Please avoid using it for inclined machining above 2°.

Example of Use

■ The discharge process consists of four steps

1. When the gap between the electrode wire and the workpiece reaches several microns, the pulse voltage across the gap breaks the insulation maintained by deionized water, resulting in electrical discharge machining (EDM).		3. Centered on the arc column, the temperature of the working fluid surrounding the arc column rises rapidly and vaporizes quickly, causing a sharp increase in volume, which leads to a local explosion in the gap and splattering of molten metal from the surfaces of the workpiece and electrode wire.
2. A pulse current is applied at the location of the electrical discharge, and the current continuously forms an arc column. Centered on the arc column, parts of the electrode wire and the workpiece reach temperatures of several thousand degrees, beginning to melt.		4. When the current supply stops, clean working fluid is introduced into the gap, cooling the molten metal, which forms fine metal particles that disperse in the water, leaving behind a crater. The gap is re-insulated, awaiting the next discharge cycle.
