Multi-Wire Saw Machine General Introduction
Multi-Wire Saw Machine for Cutting Silicon/Sapphire Ingots/Quartz semiconductor materials
The multi-wire saw is a versatile and technologically advanced cutting equipment. This specific model is meticulously designed to meet the squaring and multi-wire slicing requirements of hard and brittle materials such as sapphire ingots and quartz. It boasts exceptional flexibility and multifunctionality, capable of performing both single-wire squaring (for specialized scenarios demanding high cutting precision) and multi-wire squaring/slicing, significantly enhancing production efficiency—truly a multi-purpose machine.
Its broad application scope extends beyond sapphire ingots and quartz to include semiconductor materials, monocrystalline silicon, polycrystalline silicon ingots, and various gemstones (e.g., for squaring and slicing). During cutting, the equipment demonstrates outstanding performance, equipped with a precision temperature control system that precisely regulates cutting temperatures to prevent adverse effects of thermal fluctuations on cutting accuracy and material quality. Additionally, it is environmentally friendly and highly efficient, delivering high-precision slicing with minimal warpage and stable, reliable slice quality. Compared to traditional cutting equipment, it reduces cutting costs while maintaining quality, delivering superior economic benefits for enterprises.
Multi-Wire Saw Machine Operating Principle
The multi-wire saw operates on the principle of high-speed diamond wire carrying abrasives to grind-cut materials. The detailed process is as follows:
1. Wire Mesh Formation
- The diamond wire is unwound from the pay-off reel, guided through a precisely arranged series of guide wheels, and finally taken up by the take-up reel, forming a stable and tightly packed diamond wire mesh in the cutting zone. The pay-off and take-up reels are driven by motors with precise control to ensure the diamond wire moves continuously and at a constant speed, providing a stable foundation for cutting. The guide wheels precisely direct the wire’s path, ensuring the mesh is neatly aligned for stable and accurate cutting.
2. Workpiece Feeding and Cutting
- The workpiece (e.g., sapphire ingots, monocrystalline silicon) is fed into the cutting zone along a pre-set path and feed rate by servo-driven mechanisms, gradually approaching the high-speed moving diamond wire mesh. When the workpiece contacts the wire, the abrasive-laden wire grinds and cuts it into thin slices or specific shapes. High-precision servo motors control the feeding motion, ensuring cutting accuracy and precision.
3. Tension Control
- Tension in the cutting wire is critical. A tension control system (comprising tension sensors, controllers, and actuators) monitors and adjusts the wire’s tension in real time, maintaining it within an optimal range. Tension sensors detect wire tension and relay signals to the controller, which adjusts it via actuators (e.g., cylinders, motors) to keep the tension constant. Stable tension prevents wire breakage from excessive force or accuracy loss from insufficient tension, ensuring stable and efficient cutting.
4. Cooling and Lubrication
- Cutting generates significant heat, which can deform the workpiece or accelerate wire wear. A coolant is sprayed onto the cutting zone via a nozzle system to dissipate heat, lowering temperatures of both the workpiece and wire. The coolant also lubricates the cutting interface, reducing friction, improving efficiency, and enhancing slice quality.
Multi-Wire Saw Machine Characteristic
1.Optimized Machine Layout Design
- The machine is divided into functional zones, separating the main cutting area from the wire take-up/pay-off operation area. This design shields the wire system from external interference, improving operational stability and reliability. The open cutting zone allows easy access for routine operations and maintenance, enhancing usability and service efficiency.
2.Simplified Guide Wheel Design
- The number of guide wheels is optimized to eight, reducing traditional wheel counts. This cuts consumable usage and operational costs while minimizing energy loss and improving energy efficiency.
3.High-Quality Drive Components
- Taking the TJ450 model as an example, its key drive components (e.g., main motors, guide wheel shafts) use imported parts, ensuring higher precision and reliability. This minimizes operational errors/failures, elevating cutting quality and production efficiency.
4.Low-Noise Operation
- The machine operates at low noise levels, preventing hearing damage to operators during prolonged use and providing a healthier, more comfortable working environment.
5.Servo Motor-Driven Control
- Critical functions—wire pay-off/take-up, wire threading, spindle rotation, wire tension, and worktable feeding—are powered and controlled by servo motors. These motors offer high-precision control and rapid response, ensuring stable machine operation, cutting accuracy, and efficiency.
6.Closed-Loop Tension Feedback Control
- Wire tension (during pay-off and take-up) is regulated via closed-loop feedback: tension sensors detect real-time tension, sending signals to the controller, which adjusts it through actuators to maintain constancy. Stable tension is key to cutting precision and wire stability, directly improving quality and efficiency.
7.Tension Warning System
- An integrated tension warning function triggers alerts if abnormal fluctuations occur. Operators can promptly address issues, preventing wire breakage caused by tension instability, reducing downtime, and boosting productivity.
