Multi-Wire Diamond Saw Cutting Machine for SiC/Sapphire/Ultra-Hard Brittle Materials
The multi-wire diamond saw cutting machine is a high-efficiency, precision slicing equipment specifically designed for ultra-hard and brittle materials. It employs parallel cutting technology using multiple diamond-impregnated wires to simultaneously process multiple workpieces. This machine is primarily used for high-speed, high-efficiency, and high-precision multi-wafer cutting of materials such as silicon carbide (SiC), gallium nitride (GaN), sapphire, quartz, and ceramics, making it ideal for mass production in semiconductor, photovoltaic, and LED industries.
Compared to single-wire cutting machines, the multi-wire system significantly enhances productivity by enabling dozens to hundreds of slices per operation, while maintaining exceptional cutting accuracy (±0.02 mm) and surface quality (Ra <0.5 μm). Its modular design supports automatic loading, tension adjustment, and intelligent monitoring, meeting industrial continuous production requirements.

Diamond Wire Single-Line Cutting Machine Working Principle
The core operational mechanisms include:
1.Multi-Wire Synchronized Motion System:
- Dozens to hundreds of diamond wires run synchronously at speeds up to 1500 m/min, driven by guide wheels, achieving material cutting via diamond particle abrasion.
- Features closed-loop tension control (adjustable 15-130 N) to ensure uniform wire tension, preventing breakage or deviation.
2.Precision Feeding & Positioning System:
- Workpiece feeding is controlled by high-precision servo motors with linear guides, achieving positioning accuracy of ±0.005 mm.
- Optional vision alignment or laser tool setting enhances complex-shape cutting precision.
3.Cooling & Debris Management:
- High-pressure coolant (water- or oil-based) flushes the cutting zone to reduce thermal impact and remove debris, minimizing edge chipping.
- Equipped with multi-stage filtration to extend coolant lifespan.
4. Intelligent Control System:
- B&R servo drives (response time <1 ms) enable real-time dynamic adjustments of speed, tension, and feed rate.
- Supports parameter storage/recall and one-click material-specific mode switching.
Multi-Wire Diamond Saw Cutting Machine Key Features
