KINGRED DK7763 WIRE EDM MACHINE

Technical Description

The KINGRED DK7763 is a high-precision CNC wire electrical discharge machining (EDM) system engineered for complex contour machining of hardened materials. This machine utilizes molybdenum wire and advanced CNC control technology to deliver non-contact machining capabilities for conductive workpieces including hardened steel, carbide, and titanium alloys. The DK7763 features a robust worktable measuring 1140×750mm with X-axis and Y-axis travel of 630×800mm (approximately 24.8×31.5 inches) and accommodates workpieces up to 1000kg. Maximum cutting thickness reaches 600mm with a standard taper capacity of ±6°/80mm, expandable to ±15°, ±30°, or ±45° as needed. Performance specifications include cutting speeds exceeding 120mm²/min under standard conditions, with maximum speeds reaching 350mm²/min. Surface finish achieves Ra≤2.3-2.5μm in single-cut operations and improves with multiple passes. Machining accuracy meets GB7926-2005 standards with precision tolerances of ±0.012-0.02mm. The machine operates on single-phase 220V or three-phase 380V power (customizable), consuming approximately 1.5KW. The electrode wire diameter ranges from Φ0.12-0.20mm with a wire setting speed of 11.5m/s. A heavy-duty T-shaped bed with dual-column layout ensures exceptional stability and rigidity. The unit employs a water-based emulsion working fluid with efficient filtration systems and integrated electrolytic protection during cutting. PC/104 industrial-grade motherboard control provides stable operation in demanding manufacturing environments.
