wire EDMprecision

Product overview
Precision wire-cut EDM machine NP400L CE, submerged type, designed for accurate contouring and fine finishing of metallic workpieces. Main axes travel: X/Y 400 x 300 mm; U/V 80 x 80 mm; Z 220 mm. Suitable for unattended and multi-part production.

Highlights

• TÜV CE conformity for machine safety and design compliance.
• Power slider door to reduce installation footprint and simplify access.

Key features

• Precision
  • Smart corner control, stable discharge processing and Super Finish Circuit (SFC) for improved dimensional accuracy and surface finish.
• Efficiency
  • DPM module, precision mark control and Electrolysis Free (EF) generator system to optimise cutting performance.
• Cost effectiveness
  • Intelligent access control and wire consumption reduction functions to lower operating costs.
• Intelligent networking
  • Remote monitoring, controller connectivity and portable device support for process supervision.
• Automation
  • High-speed Auto Wire Threading, robotic workpiece transfer and probe auto measurement and correction for reduced setup time.

Linear Shaft Motor Driver System
Temperature-controlled linear shaft motor with water circulation to minimise thermal drift and improve machining accuracy. Includes 0.1 µm high-resolution digital scales and controller for precise positioning and ultra-fine finishing.

Auto Wire Threading (AWT)

• 200 mm submerged threading capability.
• Threading at 400 mm thickness from break point.
• High-speed AWT cycle example: for 100 mm workpiece thickness - wire annealing and cutting: 10 s; threading: 10 s.
• Reliable AWT supports continuous unmanned operation; water-jet assist enables threading on workpieces up to 500 mm.

On-line measurement & Multi-workpiece machining
Integrated on-table measurement and calibration reduce setup errors and cycle time. Macro commands automate reference point measurement and calibration; direct on-table checks avoid dismounting-related errors. Supports automatic 3D flatness and parallelism compensation and automatic transition to next part.
