Woodworking Band Saws
Band saws for wood are used as a cutting blade in horizontal sawing machines such as Cedar, Taiga, Altai, Master and many others.
Most often they are used for primary sawing of round timber, dividing the wood into finished edged sawn timber. The use of band saws is very economical, as the thickness of the cut is from 1.5 to 2.5 mm, which is an order of magnitude less than that of circular ones. With the correct sharpening and spreading of the teeth at the right angle, with a band saw you can cut the forest even in great frosts, without fear of waves and marriage.
Metal Band Saws
For processing and cutting metal into billets, special band saws are used. The cutting tool in them is a band saw for metal, which cuts the raw materials into ready-to-use blanks. It is used both for figured cutting and for direct cutting. Saws of this type easily cut both cast-iron ingots and stainless steel, as well as products from various hard alloys. In addition, band saws for metal are multifunctional and with their help it is possible to cut to the right sizes both foam plastic for insulation and cut plastic.
Features of sharpening band saws
Before sharpening the saw blades, it is necessary to check the angle of their wiring and make corrections if necessary. Wiring is necessary in the following cases:
- When switching to winter / summer sawing. Changing temperatures requires a different angle of inclination of the teeth.
- When sawing different types of wood.
- In case of damage to the teeth and getting under the cutting part of foreign objects during sawing.
In these cases, the wiring is simply necessary and can only be done on a special machine.
Sharpening of band saws is made daily. As a rule, saws sharpen after each shift or as they become dull. Sawing with a blunt saw threatens with poor-quality sawing, so sharpening should be done on time.
For sharpening band saws, special machines with abrasive wheels or discs are used, which allow you to process one blade band saw blade in the shortest possible time.
Benefits of Band Saw Cutting
They say that 90% of the success of high-quality sawing depends on competent wiring and sharpening of the band saw and if everything is done correctly, then you can get up to 70% of the finished timber spent on the output. That is why band saws are so popular in small businesses and private farms. In addition, there are a few fat advantages in favor of cutting with a band saw:
- Low installation costs. A massive foundation for the machine is not required and it is enough to place it on rails exposed to the level;
- Possibility of sawing logs of large diameters. Depending on the modification of the machine, the diameter of the logs can reach up to 1100 mm;
- Obtaining finished edged lumber without additional processing (CDK, multi-saws);
- Easy operation and maintenance of the machine.
It is thanks to these advantages that the band saw has become a necessary attribute in a strong economy, which allows you to save significant money on the purchase of finished lumber. The main thing when buying a machine is to immediately select a supplier of band saws that will be distinguished by enviable quality and wear resistance. When choosing such a manufacturer, you should definitely study the technical characteristics of the band saw, reviews about it and view the requirements for sharpening equipment. Special attention should be paid to bilork band saws, which are made of high-quality alloy steel and can withstand many sharpening.
During operation, they do not tear for a very long time, and special lubrication and polishing of the blade allows it to be used in conditions of constant humidity without the risk of rusting. By the way, this option is quite economical, since the cost of a bilork saw is almost 25% lower than that of its counterparts from other manufacturers.
Compact band saws for private households
There are situations when a large machine tool on the farm is simply not needed and it is simply unreasonable to spend money on it for rare sawing cases. Especially for these cases, a Makita band saw was created, which has a weight of not more than 6 kg and can be used to cut both wooden blanks and metal. The size of sawn blanks can reach up to 120mm in diameter.
Some modifications are equipped with autonomous power sources (batteries), which allow you to use the tool in hard-to-reach places without connecting to the network. It has two-speed adjustment of the cut and it is convenient and simple to work with. This option is ideal for small work volumes and narrow workpieces.
