Diamond wire enables bricking and cropping output increased.
Diamond wire is suitable to convert existing slurry saws with process support.
1. Reduced cut times
2. Cleaner and easier cooperation
3. Lower cost of ownership than comparable slurry-based systems
4. Increased productivity
5. Remarkable cutting accuracy
6. Stable, repeatable process
7. Potential kerf recycling
