1. Main application and scope of application
NST110-60 is more perfect and reasonable based on the German brand PEHAPA double-column double-cylinder double-beam structure, combined with 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 medium and small 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 deviation device, the material is more stable when cutting the workpiece, and the material utilization rate is improved.
7. Digital display of work efficiency, simple and clear work process.
8. The surface of the guide cylinder where the saw beam is installed is chrome plated + ground. The precision of the matching gap of the guide copper sleeve is matched with a precise small gap at the factory to ensure stable feeding during sawing.
9. The front and rear protection simultaneously meets the requirements to prevent the emulsion from splashing and overflowing to the workshop floor.
10. The saw blade angle torsion device should meet the requirement that the front torsion bearing adopts a flexible structure, and the rear end uses a hard alloy rigid guide wheel, and has high precision to ensure that the saw blade runs smoothly during the sawing 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.
