DF900 Multi-wire Saw is a specialized equipment deisgned for photovoltaic materials with advantages of large size, high accuracy and large capacity. It can be compatible with a variety of large-size products, and the cutting length can reach 900mm, adding a powerful tool for the photovoltaic industry.

Features

•  3 rollers design, it can achieve fast switching of multi-specification products(166, 182, 210 and 230) with high compatibility.

• Optimized cutting roller space for little wire curve, high cutting speed and high quality.

• The whole casting structure has high damping coefficient and excellent vibration damping performance.

• The wire spools are located under the cutting room and run stably, which can meet the cutting requirements of high wire speed, high quality and low wire consumption.

• Adopting high speed axle box, the maximum wire speed is up to 2400m/min with large load and high accuracy.

• Optimized rollers distance and wire winding space brings small torsion force and tension fluctuation. The unilateral torsion is less than 5 turns, and the breaking rate is less than 0.5%.

• High dynamic response closed-loop PID algorithm and cycle compensation calculation scheme, disturbance response time less than 1ms, roller diameter resolution up to 0.5um, tension control accuracy 0~0.2N, operating cutting tension fluctuation ±0.2N, tension sensor accuracy 0.001, the tension-arm swing angle less than 0.5°.

• The high-speed bus control system and the synchronous motor are used to control the high-speed water-cooled motor, which is stable and reliable and can meet the needs of the industry wire diameter requirements of various specifications for batch use.
  

• The control system saves energy and consumption, and has the function of continuous wire during power failure.
