CNC Die-sink EDM machine CNC-C50E2

CNC-C50E2 Die-Sinker EDM

The CNC-C50E2 is a high-precision 4-axis electrical discharge machine with a working travel of 400×300×300 mm (X/Y/Z). It provides excellent positioning repeatability and precise erosion pulse control. It is recommended for high-precision machining of powder metallurgy parts, difficult-to-cut materials, and special materials.

The built-in AE II (Auto-Erosion) expert system automatically optimizes multi-stage EDM parameters, minimizing thermal influence (recast layer) and guaranteeing sharp corners while maintaining nominal dimensions. Stable results are achieved even on high-hardness and porous workpieces.

Key Features:

• HEIDENHAIN linear scales (Germany) – 0.5 μm resolution, stable accuracy

• Linear guideways and ball screws: THK (Japan), precision class, high load capacity

• Work table: hand-scraped to ensure reference flatness of the contact surface

• Machine bed: high-ribbed "honeycomb" structure – maximum vibration resistance and geometric stability during long-term operation

• Multi-axis digital control system: Panasonic EtherCAT (high-speed protocol, short cycle times, precise axis synchronization)

• Operator panel: 15" touchscreen running Windows – intuitive interface with icons and detailed tooltips for each parameter

• Built-in database of >1,000 machining technologies (electrode material, workpiece material, cavity configuration)

• Electrode jump speed (Z-axis): 14 m/min – effective removal of debris from the erosion zone, critical for deep cavities and holes. Performance comparable to linear motors but without the risk of spindle dropping upon power loss.

• Specialized machining modes:

  • Carbide (hard alloys) – high speed, minimal electrode wear, Ra ≤ 0.2 μm

  • Graphite – high speed, low electrode wear

  • Large areas – uniform roughness without carbon deposits or black spots (flatness ≤ 5 μm)

Applications:

Manufacturing of molds and dies (including miniature electronic components); powder metallurgy – shaping of complex-profile parts from special materials without mechanical stress; aerospace industry – machining of superalloys and nickel-based alloys; automotive production – injection molds, dies, precision fuel system components; medical technology – implants, surgical instruments, micro-EDM; production of carbide tools (tungsten carbide).
