Structural Features(Wire EDM Machine EFH43S )
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 EFH43S 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
- 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.
