Frequently Asked Questions
Minnuo’s medium speed wire EDMs are ideal for precision molds, complex mechanical parts, fine stamping dies, connector components, and electronic parts requiring high dimensional accuracy and good surface finish.
Medium speed wire EDM combines the low cost of fast wire EDM with better accuracy and surface finish close to slow wire EDM, using one-time cutting plus multiple skim cuts to balance precision and efficiency.
Minnuo’s medium speed wire EDM machines achieve positioning accuracy within ±0.005 mm, surface roughness up to Ra 0.8–1.2 μm, and can support multi-pass fine cutting.
Absolutely! Send us the workpiece material, thickness, dimensional tolerance, and we’ll recommend the most suitable medium speed wire EDM model within 10 minutes.
Yes! We offer customizations like worktable size, maximum cutting thickness, wire diameter compatibility, water tank capacity, CNC controller brand, and automatic wire threading (AWT) systems.
We use high-rigidity casting structures, precision ball screw drives, high-frequency power supplies, and perform multi-cut testing and laser interferometer calibration before shipment.
Standard models are delivered within 20–30 working days. Customized models or machines with AWT systems typically require 30–45 working days.
Minnuo provides a one-year warranty, 24/7 technical support, remote training, troubleshooting assistance, and long-term spare parts availability.
