Frequently Asked Questions
Minnuo’s EDM drilling machines are perfect for hard materials and components like aerospace turbine blades, mold cooling holes, nozzles, ejector pins, and fuel injectors, requiring fine and deep hole drilling.
EDM drilling can process hardened steel, stainless steel, titanium, carbide, copper, aluminum, and nickel-based alloys, regardless of material hardness.
Minnuo’s EDM drills can produce holes from Ø0.3 mm to Ø6.0 mm, with depth-to-diameter ratios exceeding 300:1, achieving high aspect ratio deep holes efficiently.
Absolutely! Just send us the hole diameter, depth, material, and production volume, and Minnuo’s engineers will recommend the most suitable EDM drilling machine model within 10 minutes.
Yes! We offer customizations for maximum machining depth, machine table size, dielectric system configuration, automatic electrode changers (AEC), and CNC or manual control systems.
Minnuo EDM drills use servo-controlled feed systems, high-frequency pulse power supplies, real-time monitoring systems, and undergo sample testing and calibration before delivery.
Standard models can be delivered within 20–30 working days. Customized or special configurations usually require 30–45 working days.
Minnuo provides a one-year warranty, 24/7 technical support, free online training, remote troubleshooting, and lifetime spare parts service.
