Detailed Diagram of Diamond Wire Cutting Machine
Overview of Diamond Wire Cutting Machine

The Diamond Wire Single-Line Cutting System is an advanced processing solution designed for slicing ultra-hard and brittle substrates. Using a diamond-coated wire as the cutting medium, the equipment delivers high speed, minimal damage, and cost-efficient operation. It is ideal for applications such as sapphire wafers, SiC boules, quartz plates, ceramics, optical glass, silicon rods, and gemstones.
Compared with traditional saw blades or abrasive wires, this technology provides higher dimensional accuracy, lower kerf loss, and improved surface integrity. It is widely applied across semiconductors, photovoltaics, LED devices, optics, and precision stone processing, and supports not only straight-line cutting but also special slicing of oversized or irregularly shaped materials.

Operating Principle
The machine functions by driving a diamond wire at ultra-high linear speed (up to 1500 m/min). The abrasive particles embedded in the wire remove material through micro-grinding, while auxiliary systems ensure reliability and precision:
-
Precision Feeding: Servo-driven motion with linear guide rails achieves stable cutting and micron-level positioning.
-
Cooling & Cleaning: Continuous water-based flushing reduces thermal influence, prevents micro-cracks, and removes debris effectively.
-
Wire Tension Control: Automatic adjustment keeps constant force on the wire (±0.5 N), minimizing deviation and breakage.
-
Optional Modules: Rotary stages for angled or cylindrical workpieces, high-tension systems for harder materials, and visual alignment for complex geometries.
