Product Introduction

The Diamond Wire Single-Line Cutting Machine is an advanced solution engineered for slicing and shaping ultra-hard and brittle materials. By employing a diamond-coated wire as the cutting medium, the system delivers high-speed, low-damage, and cost-efficient processing. The equipment is particularly well-suited for applications involving sapphire wafers, SiC ingots, quartz plates, ceramics, optical glass, silicon rods, and jade.

Unlike traditional sawing or abrasive wire systems, this technology provides finer accuracy, reduced kerf loss, and improved surface smoothness, making it an indispensable tool across industries such as semiconductors, photovoltaics, LEDs, optics, and gemstone finishing. It excels not only in straight cuts and truncation but also in specialty slicing for oversized or irregular geometries.

Core Working Principle

The machine operates by driving the diamond wire at ultra-high speeds (up to 1500 m/min), where the abrasive diamond particles grind through material surfaces. Several supporting systems ensure cutting precision and reliability:

• Precision Feed Control – Servo-driven feeding system with linear guide rails ensures stable positioning and micron-level accuracy.

• Coolant and Cleaning System – Continuous water-based flushing reduces thermal effects, avoids cracks, and removes debris efficiently.

• Wire Tension & Bow Management – Automatic tension adjustment minimizes deviation, maintaining consistent cut thickness.

• Optional Extensions – Rotary worktables for multi-angle cutting, high-tension modules for extreme hardness, and visual alignment aids for complex structures.
