Diamond Wire Single / Multi-Wire Dual-Station Cutting Machine For Sapphire / SiC Material Processing
Introduction of diamond wire single/multiple wire saw machine
Diamond Wire Single/Multi-Wire Dual-Station Cutting Machine for Sapphire/SiC Material Processing
The diamond wire single/multi-wire dual-station cutting machine is a core equipment for precision processing of brittle materials. By utilizing the high-speed reciprocating motion of diamond wire (steel wire coated with silicon carbide/aluminum oxide particles) and relative abrasion with workpieces, it achieves accurate cutting of hard materials. The "dual-station" design allows simultaneous accommodation of two workpiece fixtures (or alternating operations), significantly enhancing production efficiency. It is widely used for squaring, slicing, and precision shaping of materials such as semiconductor wafers, sapphire, silicon carbide (SiC), ceramics, quartz, and precious metals.
This machine integrates servo control systems, tension regulation, and oscillating cutting technologies, balancing efficiency and precision. It serves as a critical tool in industries like photovoltaics, semiconductors, and advanced manufacturing.

Working principle of diamond wire single/multiple wire saw machine
The operational logic revolves around "diamond wire abrasion + workpiece feed":
1. Diamond Wire Cycling:
- A high-speed rotating capstan drives the diamond wire in reciprocating linear motion (or unidirectional cycling).
- The wire is tensioned by tension wheels (spring-loaded or pneumatic) to form a stable cutting wire network.
2. Workpiece Feed:
- Servo motors control the workpiece fixture (one in the dual-station setup) to move toward the diamond wire at a constant speed, or vice versa, generating relative abrasion for cutting.
3. Dual-Station Switching:
- After completing one workpiece, the machine automatically switches to the other fixture, enabling continuous operation without downtime.
4. Key Technologies:
- Oscillating Cutting: Models employ a ±8° oscillating worktable to ensure uniform wire contact and improved surface flatness.
- Tension Control: Sensors monitor real-time wire tension, preventing slippage or breakage.
