Probably the best invention for the wood industry became the band saw wood, which allows to accurately split the log, the number and waste shavings are minimal.
To understand the importance of such drinking, have to go back in time. Old saw blades used for sawing woods, was huge, had significant shortcomings, a large cutting width, a fixed period allowing to work effectively only with logs of a certain thickness. If the logs were thicker or thinner, the amount of waste was simply arresting. But in the Soviet Union for such things, nobody paid attention, because the raw material was virtually free.
The Situation changed radically with the advent of the market economy, because the wood had been buying, and nobody wanted to pay money for waste. The old sawmills came bandsaw for wood. Due to its design, it can cut boards of any thickness, making the minimum cut, the result is a huge savings of raw materials and the ability to make boards for different workpiece. Also band saw blades for wood is very compact, they can be effortlessly transferred to a new location to reduce the cost of shipping raw materials, and in case of breakage of an ordinary mechanic can fix.
The Simplicity of the design that has the band saw on wood, is just amazing. A stationary base on which is mounted a log, and a carriage with two drums, which stretches the saw. The reels start spinning and the saw cuts to work enough medium speed of an electric motor. The carriage moves along the log and cut boards to the desired thickness, the thickness of each subsequent Board is controlled by the operator, which allows to obtain the maximum quality of the products. Such band saws for wood are called horizontal. Their advantages are undeniable.
In addition, the band saw that the tree can be vertical. These options used to work with small parts and for cutting shorter logs. Here the design is slightly different, but also very simple. Saw the drums spinning vertically, and the carriage with the clamp, which is inserted into a material, moving along it. Working with a saw is much safer and more accurate than with other woodworking machines.
The Very fabric of the band saw also needs constant care in sharpening and divorce. Sharpening - the most simple of operations with the paintings, it is done on a special machine, which included band saws on wood. Divorce teeth of the fabric determines the thickness of the cut and the intensity of the emission of sawdust. For each tree there are certain standards of divorce, minimum 5 mm each side for the hard wood, a maximum of 25 mm for soft rocks. Adherence to these rules guarantees a long service tracks, the production quality and speed. During the change of cloth on the reels you need to follow the force of its tension, to avoid defective products or rupture of the canvas.
