Wire EDM Machine AC Servo

Wire EDM Machine-SI Series

  • “C” type structure and “T” type machine base for higher accuracy and longer lifetime.
  • Integrated type without individual control cabinet for space saving and humanized operation.
  • Patented Esuntek V3.5spark power generator improves 20% efficiency.
  • Independent wire routing design with two-way constant tension system.

Structural Features (Wire EDM Machine SI Series)

Machine Tool Bed

1. The machine tool bed adopts a C-type structure;

2. The machine tool bed is made of high-strength cast iron and undergoes heat treatment to improve internal stress distribution.

This improves rigidity and long-term dimensional stability;

3. This machine uses a Panasonic servo motor drive system. The machine’s motion accuracy is precisely tested during assembly and tested with a laser interferometer before leaving the factory.

4. This machine tool uses THK guideways, which are precision ground once to ensure smooth movement and high precision.

A centralized lubrication system further enhances durability and reduces wear.

The mechanical structure of the EFH65S is designed to ensure long-term stability, high precision, and minimal maintenance requirements.

Guideway Structure

1. Guideways on the same plane are machined in one piece using a professional grinding machine;

2. The guideway mounting structure of this equipment is a double-plane design;

3. The guideways of this equipment adopt an automatic lubrication system;

5. The motion accuracy of the guideways in all directions is guaranteed by assembly precision.

Wire Feeding System

The wire feeding system employs a constant tension mechanism to maintain stable cutting conditions.

This helps reduce wire breakage and improve overall machining quality.

Cutting Fluid System

A four-stage filtration system ensures the cutting fluid remains clean, thereby improving machining stability and extending part life.

The closed-loop design also prevents cutting fluid splashing and maintains a clean working environment.

Pulse Power Supply Features(Wire EDM Machine)

  • ESUNTEK’s proprietary pulse power supply is built with high-performance VMOS MOSFET or IGBT switching technology, ensuring ultra-fast switching response, low power loss, and outstanding energy efficiency.
  • Advanced multi-waveform pulse control (Rectangular, Comb, Stepped, Bidirectional, and Composite Pulse) optimizes spark discharge, minimizes arcing and electrode burning, and significantly improves machining stability.
  • Scalable parallel power module design delivers exceptionally high current output for efficient machining of thick materials and demanding high-speed EDM operations.
  • Flexible multi-step or stepless peak current adjustment supports roughing, semi-finishing, and precision finishing with optimal machining performance.
  • A fully digital DSP/FPGA control platform performs nanosecond-level real-time discharge monitoring for intelligent pulse regulation, ensuring stable machining accuracy and higher efficiency.
  • Integrated multi-layer protection, including overcurrent, overvoltage, overheating, and abnormal discharge protection, guarantees safe and reliable long-term operation.
