1. Main application and scope of application
NST130-80 is more perfect and reasonable based on the German brand PEHAPA double-column double-cylinder double-beam structure, combined with the 20 years of R & D experience of its own sawing machine, and has obtained a national invention patent (patent number: ZL201510260342.1) The structure is scientific and reasonable, the appearance is generous, the cutting efficiency is high, and the service life of the band saw blade is long. It is an ideal cutting equipment for large and medium-sized materials. This machine tool is mainly used for sawing ferrous materials. The material shape can be round or rectangular.
2. Main features:
1. Dual hydraulic control sawing feed speed, stepless speed regulation, more stable when sawing.
2. The band saw blade hydraulic tension is easy to install and tension, easy to operate and maintain.
3. The linear speed of the saw blade adopts frequency conversion speed regulation, which can be used for sawing different materials.
4. Sawing is stable and high precision.
5. The work clamp adopts hydraulic pressure, and the operation is quick and convenient.
6. Equipped with saw deflection device, when the workpiece is deflected, the machine will automatically stop and improve the material utilization rate.
7. Digital display of work efficiency, simple and clear work process.
3. Working environment:
1. The ambient temperature is higher than 0oC
2. The relative humidity of the air is not more than 85% (equivalent humidity is 20 ± 5 oC)

V. Main mechanical structure
1. The machine feet are welded steel plates, the left side is a hydraulic oil tank and hydraulic system, and the right side is a combination of a cooling system equipped with a cooling pump and coolant.
2. The beam is a steel plate welded part, which is composed of a worm gear reducer, a saw wheel, a band saw blade guide device, a guard protection, a saw blade tensioning device, a beam, and a guide device.
3. The band saw blade is installed on the two wheels and the guide device. After the driven wheel is tensioned, it is driven by the main motor. The band saw blade can make a circular movement around the two saw wheels to realize the main sawing movement. The saw beam is installed on the cylinder to guide the upward and downward movements, so as to complete the retracting and feeding movements.
4. The main transmission system is installed on the saw beam and is composed of the main motor, belt wheel and worm gear reducer. Frequency conversion speed regulation to meet the requirements of sawing different materials and materials.
