In the fields of precision mold making, aerospace, and 3C electronics manufacturing, both machining accuracy and operational efficiency are indispensable. The EXCETEK NP400L (and its upgraded NP400L Plus) from Taiwan's Jingcheng Technology has become a representative of high-performance slow wire EDM machines thanks to its linear motor direct drive, next-generation energy-saving discharge circuit, and intelligent controller.

Three core technologies to solve user pain points

1. High-thrust linear motor drive

Zero backlash, zero wear, maintaining a machining accuracy of ±5μm over a long period.

Equipped with a 0.1μm optical scale and a constant temperature system, thermal deformation is minimal.

Maintenance-free design significantly reduces operating costs.

2. GS High-Speed Energy-Saving Discharge Circuit (Plus Version)

Maximum processing speed 320 mm²/min, a 25% increase in speed.

Energy saving of 33%, energy recovery rate of 25%.

Awarded TMBA Energy Saving Label Gold, the first choice for green manufacturing.

3. W600I Intelligent Controller

Computing performance improved by 6 times, and real-time performance improved by 4 times.

Full closed-loop servo control + EtherCAT axis control for greater stability on complex curved surfaces.

Automation and intelligent monitoring

High-speed automatic threading: Supports ultra-fine wire diameters of 0.07mm, threading thicknesses up to 500mm underwater, direct threading even at break points, enabling 24-hour unmanned operation.

Remote monitoring: Supports OPCUA/UMATI protocols, allowing you to view machine status anytime via a web interface.

AI-powered multilingual support: Real-time remote assistance in ten languages
