Multi-Wire Saw Cutting Machine for Natural Stone Processing
The multi-wire saw cutting machine is a modern stone processing equipment that utilizes multiple diamond cutting wires working in parallel, specifically designed for efficient cutting of natural stones such as marble, granite, and sandstone. Through the synchronous movement of hundreds of diamond wires, it enables one-time cutting and shaping of extra-large blocks (up to 3×2×2m), improving cutting efficiency by 5-8 times compared to traditional frame saws. The equipment features a modular design, supports vertical/horizontal bidirectional cutting, and offers a maximum processing thickness of 2.5m. It is widely used in stone quarry mining, slab production, and special-shaped material processing.
Multi-Wire Saw Cutting Machine Working Principle
1. Multi-Wire Transmission System
- Driven by a main motor, the drive wheel set (diameter 1.2-1.8m) powers 200-800 diamond cutting wires to form a closed-loop motion network.
- Wire speed is adjustable within the range of 0-25m/s, with servo tension control (15-35kN adjustable) ensuring taut cutting wires.
2. Stone Feeding System
- The block trolley is uniformly fed at a speed of 0.5-10cm/h via a hydraulic propulsion device.
- Equipped with pressure sensors to monitor cutting resistance in real-time and automatically adjust feeding speed.
3. Cooling and Dust Removal System
- High-pressure water pumps (10-15MPa) spray water-based coolant at a flow rate of 200L/min.
- Two-stage purification with cyclone dust removal + water curtain filtration controls dust concentration below 2mg/m³.
4. Intelligent Control System
- Based on a PLC + industrial computer architecture, it displays real-time parameters such as wire tension, current load, and feeding speed.
- Features stone hardness adaptability, automatically optimizing cutting parameters through acoustic detection.

Multi-Wire Saw Cutting Machine Characteristics
- Key transmission components utilize imported parts to ensure overall machine precision.
- The equipment operates with low overall noise levels, preventing hearing damage to workers.
- Wire payout, take-up, arrangement, spindle operation, cutting wire tension, and worktable feeding are all driven and controlled by servo motors.
- Uninterruptible power supply (UPS) is integrated for continuous operation.
- Closed-loop feedback control is adopted for wire payout and take-up tension, ensuring constant cutting wire tension during the process.
- The system features tension (early warning functionality), effectively preventing wire breakage caused by abnormal tension fluctuations.
Multi-Wire Saw Cutting Machine Main Applications
1. Direct Quarry Mining
- Replaces explosive mining methods, enabling direct rectangular block cutting from ore bodies, improving yield by 3 times.
- Particularly suitable for protective mining of high-value stones like white marble and Indian red granite.
2. Large-Scale Slab Production
- Simultaneously cuts 120-240 standard slabs (thickness 1.5-2cm).
- Achieves one-time forming from rough to glossy surface, eliminating rough grinding.
3. Special-Shaped Material Processing
- Enables curved cutting (min. radius R300mm) via CNC system.
- Used for special-shaped processing such as Roman columns, sculpture blanks, and curved stair treads.
4. Ancient Building Restoration
- Precisely replicates traditional stone components, meeting mortise and tenon fitting requirements.
- Enables damage-free cutting of soft stones like sandstone and bluestone.
5. Special Stone Processing
- Crystal agate slicing: Uses 0.5mm ultra-fine diamond wire with cutting loss <1mm.
- Tombstone engraving: Supports 45° bevel cutting and processing.
