100 Years of Band Saw
The band saw has a history of about 92 years. The first band saw was invented in the United States in 1926 and has survived many changes. After it was invented, it was made and used in carbon steel until 1968, and it was used for about 15 years starting from 1968. The band saw reached its present state in 1983 with the use of a bi-metal saw. It was obtained by combining bi-metal spring steel and high-speed steel and proved to be much higher than carbon or matrix. In the 90s, carbide saws were put on the market and entered the production lines in order to increase the need for productivity and to obtain fast and precise results in a shorter time.

Unlike carbide saw blade bi-metal teeth have carbide parts at their ends and can withstand higher temperatures than the bi-metal saw is based on. Bi-metal saws can withstand temperatures of 700-750 degrees, while carbide tipped saws can withstand temperatures up to 1700-1800 degrees. This allows for faster, more efficient and long-lasting cutting results. In addition, the carbide tip saw is much harder than bi-metal, except for temperature, so it can be used for cutting harder or more abrasive materials.

The carbide-tipped saw requires a far different cutting process than using a regular saw. As a first priority, the machine on which the carbide saw will be used should not be stable and does not cause vibration, and preferably the machine should be a columnar machine. Because carbide is a much harder but more brittle material than bi-metal, vibration is the number one enemy. In addition, printing and belt speeds can be applied in the most accurate way on the machine so that there is no loss or life problem during cutting. At the cutting start point, the carbide saw can never be operated without lapping cutting.

If this happens, it will not show much performance difference from a bi-metal saw and it will be harder to get the results we want. When making lapping cutting, firstly starting from bi-metal cutting settings, firstly the belt speed should be increased and then the printing speed should be increased and this process should be continued for minimum 30-45 minutes. To give an example, when you cut a material with a diameter of 1000 mm in practice with a bi-metal saw in 10 hours, it completes the same material with a carbide saw in as little as three hours and gives us about 6-7 hours.

As a result, your production capacity increases and it does not cause loss of time and productivity. Turkey in advancing this perception a bit different and a little more behind we come primarily from developed countries. The main purpose of use in Turkey carbide saws cut the speed or efficiency, but rather diffucult materials or which is part of the high temperature of the cast steel arise during cutting. Although it has started for this purpose in Europe or America, usage has become more important in terms of efficiency and time saving. In Turkey, this perception is slowly sit down and start seeing significant demand from users. Bandsaw and efficiency in use today is a rising trend in Turkey is one of the most important sectors of the increasing importance of production costs and speed.
