Frequently Asked Questions

1、What types of materials are suitable for CNC abrasive wire cutting machines?

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.

2、What is the working principle of abrasive wire cutting?

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.

3、What machining accuracy and surface finish can be achieved?

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.

4、Can you recommend a model if I provide material type and thickness?

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.

5、Can your machines be customized?

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.

6、How do you ensure machining precision and wire stability?

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.

7、What is the delivery time for CNC abrasive wire cutting machines?

Standard models are delivered within 30–45 working days. Customized or high-end versions usually require 45–60 working days.

8、What after-sales services are provided?

Minnuo provides a one-year warranty, 24/7 technical support, remote online guidance, on-site commissioning services, and long-term spare parts support.
