1. The gap between the guide blocks on the band saw is not suitable, and the back of the saw is pressed too heavily, resulting in excessive tension at the tooth root of the saw belt, resulting in cracks and breakage. Inspection method: adjust the sawing points of the two wheels, make the two saw arm clamps at the same level, and keep the saw back and the shoulder of the saw blade at a certain distance.
2. Severe wear of the guide block causes the back of the saw to be worn, causing cracks on the back of the saw and causing the band to break. Inspection method: always check the guide block alloy for obvious wear marks and grooves, and check the saw back for irregular scratches and breaks at the scratches.
System function of band saw
1. Hydraulic transmission system: It is composed of pumps, valves, cylinders, oil tanks, pipelines and other auxiliary parts. The lifting of the saw beam and the clamping of the workpiece are completed through electrical control to meet the sawing needs of different materials.
2. Electrical control system: It is composed of electrical box, control box, junction box, travel switch, electromagnet, etc. It is used to control the functions of the saw blade and make it work normally.
3. Lubrication system: The system seems simple, but in fact it is very important. Because the equipment is not lubricated, it is prone to mitre cuts, wear equipment, and reduce the service life of band saws and saw blades.
