Stepper Integrated Wire EDM Machines

The Stepper Integrated Wire EDM Machines are high-performance, cost-effective solutions for precision wire cutting using molybdenum wire. Designed with an integrated structure and powered by a stepper motor system, these machines deliver exceptional accuracy (±0.005mm) and a superior surface finish (Ra ≤1.0μm). With adjustable wire travel speed, ±6°/80mm taper cutting capability, and compatibility with medium-speed wire cutting fluid, the series meets the needs of small and large-scale manufacturers alike. Available in a range of models from E35 to E80F, they support workpieces up to 2600kg and 500mm in thickness—perfect for complex mold making, tooling, and precision part production.

1. High Cutting Accuracy: Delivers machining accuracy of up to ±0.005mm and finishing accuracy ≤0.01mm.

2. Superior Surface Finish: Achieves surface roughness as fine as Ra ≤1.0μm, suitable for high-finish applications.

3. Wide Taper Cutting Capability: Supports ±6° taper cutting over 80mm thickness for versatile machining tasks.

The device features a high-frequency discharge system with high efficiency, low wire consumption, and easy adjustment. It can process materials up to 300mm thick with ease and can handle thicknesses exceeding 1000mm. For materials within 300mm thickness, the cutting is stable and fast, producing smooth surfaces without noticeable directional marks. Under normal operating current of 7-9A, the machining efficiency exceeds 12,000 mm²/hour, ranking it among the top performers in the industry.

The system offers a high level of automation with features such as edge detection, centering, axis shifting, and more. Operators can easily achieve machining tasks with minimal input. Key functions include multi-directional edge finding, slot centering, rectangular centering at various angles, three-point circle center location, rectangle frame centering, internal and external corner detection, and automatic angle alignment. For each probing operation, users can adjust the number of points and probing speed as needed to meet specific accuracy requirements.

The machine bed is made of high-strength cast iron with a T-shaped base and C-frame structure, providing excellent rigidity and strength. This design ensures good vibration resistance, stable accuracy, and long-term precision retention, making it ideal for high-precision EDM operations.

The electrical control board is independently developed in-house, ensuring full compatibility with the machine’s hardware and software systems. This self-developed design allows for greater customization, improved reliability, and more precise control over the EDM cutting process, resulting in enhanced performance and long-term stability.
