Electrical spark machining one of precision mechanical processing technology modern and increasingly widely used in the industries of automobile, motorbike, electronics, aircraft, medical, etc. The machine uses electrode wire as a cutting tool, controlled by a control system. Numerical control, according to the predetermined trajectory, cutting and machining components. The electric spark machining machine Often used to process molds and mechanical products that require high precision, difficult profiles and high hardness that are ineffective or cannot be processed on conventional machine tools.
