Frequently Asked Questions
Minnuo’s CNC abrasive wire cutting machines are ideal for hard and brittle materials such as sapphire, silicon wafers, silicon carbide, ceramics, quartz, magnetic materials, and rare metals.
A diamond-coated or abrasive wire continuously moves through the workpiece under controlled tension, achieving precise material removal by micro-grinding action, ideal for high-precision, low-damage cutting.
Our machines achieve cutting accuracy within ±0.01–0.02 mm, and surface roughness Ra 0.4–0.8 μm, depending on material properties and cutting parameters.
Absolutely! Just send us your material type, block size, required cut thickness, and tolerance, and Minnuo’s engineers will recommend the best abrasive wire cutting machine within 10 minutes.
Yes! We offer customizations including cutting stroke (X/Y/Z), maximum workpiece size, wire type (single wire/double wire), tension control system, and CNC system brand based on customer requirements.
Minnuo machines feature high-stability tension control, servo-driven wire feeding, constant wire speed regulation, and are calibrated with laser interferometer and precision measuring instruments before shipment.
Standard models are delivered within 30–45 working days. Customized or high-end versions usually require 45–60 working days.
Minnuo provides a one-year warranty, 24/7 technical support, remote online guidance, on-site commissioning services, and long-term spare parts support.
