Frequently Asked Questions

What is the maximum taper angle that your wire EDM machines can achieve?

Our machines can achieve a maximum taper angle of 45 degrees, depending on the workpiece height and wire diameter. For workpieces up to 300 mm, we maintain high accuracy with a deviation of ±0.005 degrees. This is verified through our precision calibration system, which uses optical encoders. Our technical team can assist in selecting the optimal parameters for your specific application, ensuring that you meet tight tolerances without compromising surface finish.
Taper cutting can cause a slight degradation in surface finish due to the inclined angle, but our advanced pulse control and optimized flushing mitigate this effect. In standard fin-cut conditions, we achieve Ra 0.4 µm on taper angles up to 30 degrees, and Ra 0.6 µm for angles up to 45 degrees. We also offer multiple trim passes that can improve the finish to Ra 0.2 µm. Our machines are designed to minimize recast layer, preserving the integrity of the part.
Our wire EDM machines are suitable for any conductive material, including hardened steel, aluminum, titanium, copper, and carbide. We have successfully processed metal matrix composites and superalloys used in aerospace and automotive applications. The wire electrode is selected based on the material hardness and required precision. Our team provides comprehensive guidelines to ensure optimal cutting performance and minimal wire breakage.
Our machines feature a closed-loop control system with real-time monitoring of wire position and tension. We incorporate artificial intelligence algorithms that compensate for wire bending and thermal drift, maintaining the desired taper angle throughout the machining process. Additionally, we recommend periodic calibration using our standard reference blocks to sustain long-term accuracy. In a case study, we maintained continuous 24-hour operation for 5 days with a repeatability of ±0.005 mm on a complex multi-angle part.
