VI. Main Specifications
1. The machine adopted new technology platform, which can effectively improve the problem of broken wire and wire loss in continuous large current processing, achieve high current cutting for a long time (when processing current is 5A, continuous time is more than 72 hours; when processing current is 7A, continuous time is more than 45 hours).
2. Wire-cutting CNC electric control cabinet are produced by using the "heat pump" cooling patented technology, which take the electric elements' own heat into air's convection power for heat dissipation , by this, it can greatly reduce amount of dust workshop into the electric control cabinet, prolong the service life of equipment, reducing energy consumption, reducing the fan noise and achieving the aim of energy conservation and environmental protection.3. Continuous high efficiency cutting without breakage.
For 60 mm thick type of 45 steel:
When the cutting speed is in 167 mm2/min, the life of electrode wire is about five hundred thousand mm.
When the cutting speed is in 120 mm2/min, the life of electrode wire is about one million mm.
The life of electrode wire: The total cutting area from the new discharge for cutting to the first time of wire's broken. In accordance with the the above cutting speed, The surface roughness of workpiece Ra≤5.0µm.
4. Low wire loss
