When cutting sapphire, traditional fine diamond wire typically operates at slow reciprocating speeds, resulting in long processing times. By contrast, a larger-diameter Diamond Coated Wire Loop dramatically improves cutting efficiency while maintaining excellent surface quality.

Our diamond coated wire loop (Ø0.7 mm × 4000 mm) is engineered for high-performance sapphire cutting applications. At a wire speed of 20 m/s, it can cut a 2–3 inch sapphire in approximately 30 minutes, significantly reducing production time compared to conventional methods.

To achieve optimal performance, operators should fine-tune parameters such as wire speed, feed rate, tension, and coolant flow based on the specific sapphire grade and cutting requirements. Regular inspection and timely replacement of the wire loop are also recommended to maintain consistent results and prevent unexpected breakage.

🔹 Recommended Operating Procedure

1. Securely mount the sapphire on the cutting machine fixture.

2. Install the diamond coated wire loop and verify proper alignment.

3. Set machine parameters to the recommended wire speed, tension, and feed rate.

4. Start the cutting process, allowing the loop to run smoothly across the workpiece.

5. Monitor cutting stability, coolant supply, and surface quality.

6. Stop the machine once the target thickness and finish are achieved.

🔹 Process Optimization Tips

• Adjust wire speed according to sapphire hardness and diameter

• Maintain stable feed pressure to avoid wire overload

• Ensure adequate coolant flow for heat removal and debris flushing

• Inspect wire wear regularly and replace when cutting efficiency drops

• Use proper wire tension to prevent vibration and breakage
