How to use horizontal band saw?

The aim of cutting with horizontal band saw is to cut the saw blade quickly and increase the cutting efficiency. What angle should be selected for the tooth profile of the horizontal band saw machine, and the addition of several cutter teeth should be determined according to the hardness, wetness, cutting difficulty, physical strength and physical strength of the saw material. The cut saw should have the same angle of each tooth, with the sharp edge of the tooth and the surface of the saw at a 90 degree angle (except for the knife tooth), so as to eliminate the phenomena of uneven T-idle, high consumption of force, easy jumping and blunt cutting caused by uneven cutting edge and high and low teeth. However, it is allowed to have the same height and low on a certain internal arc.

The sawing method of the horizontal band saw machine uses a saw horse to clamp the saw blade, the human body presses the saw horse, the two hands hold the saw horse together, there is a board to be touched on the ground, a mouth to clamp the saw blade is sawed on the top of the pole, the saw blade is clamped inside, then the two hands hold the key together, there is a human body sitting on an object below 130mm high, the right leg is curled up flat, the left leg is curled up to stand up, the left hand holds the saw blade on the left calf, and the right hand holds the saw blade. In the process of cutting a saw, there are those who are handed over, those who are roughly cut down, and those who are carefully cut down. All those who are handed over should be cut down one by one from the lower end of the saw. The reason is that there is a slight curling edge after the sawtooth chisel edge is tapered. The upward curling of the edge hinders the sawing efficiency, while the downward curling of the edge helps the sawing efficiency.

The loosening tension is to loosen the saw screw a few times to prevent the saw crank from deforming under long-term compression, reduce the elasticity and affect the use. It can be implemented at the end of one day or at intervals of several days. It can be unloaded once a week during the dry season. In practice, if fine hemp rope is used for tension, special attention should be paid to prevent hemp rope from absorbing moisture and expanding in rainy days, and shorten the length to break the saw crank.

Wiping oil is to regularly brush varnish on saw crutches and saw beams within one year or one and a half years to prevent moisture and deformation. Saw blade oil shall be selected from oils that can prevent rust when stored and lubricate when used.
