In modern industry, horizontal band sawing machines are widely applied in a wide variety of industrial applications. Regarding the major applications, a horizontal band sawing machine is used particularly in metalworking, woodworking, and lumbering sectors, but can also be used to cut a variety of other materials. Compared with ordinary circular sawing, the primary advantages of horizontal band sawing machines include uniform cutting movement as a result of an evenly distributed tooth loads, and the capability to cut irregular or curved shapes like a jigsaw. Speaking of the curve scales, the minimal radius of a curve is decided by the width of the saw band and the curves.
In addition to the radius issue, the speed of the band is also decided by other major considerations, which ranges from around 0.20 meters per second to 25 meters per second. In some specific band sawing models such as customized band saw machines which are designed for friction cutting of extra-hard metals, those kinds of machines can run its band speeds around 76 meters per second, granting a large productivity as well as efficiency for the production lines.
Because the horizontal band sawing machines are sawing equipment that are designed for industrial metal-cutting use, here are some of the metalworking applications. They are the long work piece cutting tasks such as for construction steels in fabrication shops and for bar stock in machine shops. Band saw machines are available in both vertical and horizontal designs and both kinds are with different advantageous features.
Horizontal band sawing machines have the work piece clamped while the sawing blade swings down through the cutting. This design configuration is used to cut long materials such as tube or solid bar stock to length. Accordingly, it is a crucial procedure of the equipment in most machine shops. Meanwhile, the horizontal design is not handful for cutting certain profiles such as curves or other complicated shapes. Because small horizontal band saws typically utilize gravity feed only. For industrial models, the rate of the descent is usually decided by a hydraulic cylinder that bleeds via an adjustable valve unit.
Today, both wood working and metalworking operators know how harmful chips can cause during the operation. That’s why metal-cutting band saw machines are often equipped with brushes or brush-wheels for the prevention of chip stuck in between the blade’s teeth.
Besides, in order to cool the blade, systems with cutting fluid is a must have for band saw machines, because the coolant can wash away the chips while keep the sawing blade cool as well as well-lubricated. On the other hand, for the CNC mode, more sophisticated versions of this type of sawing are partially automated through the PLC or CNC control systems. This kind of control is designed for large volume production model. Besides the horizontal and vertical categories, there are mainly two kinds of sawing machines in the industrial market: band sawing machine and circular sawing machine.
Unlike band sawing machine which we have introduced for a while, circular sawing machine utilizes circular tools to process sawing procedure rather than sawing bands to achieve the cutting mechanism, which leads to other machining features that is different from band sawing mechanism. On the other hand, a band saw is also called as band sawing, which is a powered sawing machine with a long and sharp blades consisting of a continuous band of toothed metal stretched between wheels to cut targeted materials with a continual sawing pace.
Therefore, this horizontal sawing machining method could be done on different phases and directions. In the metalworking sector, sawing process of horizontal sawing machines cover a wide variety of various operations and ranges a wide scale from single tiny parts to heavy and large sawing operation duties as well as missions. Now many of the large-sized sawing structure can stand with huge vibrations caused by cutting movements. Although it is not like the gantry designs of machining centers, still, they are firm and stable for offering steady sawing performance.
On the other hand, circular sawing machine utilizes circular tools to conduct sawing procedure rather than sawing bands to achieve the cutting mechanism, which leads to other machining features that is different from band sawing methodology. Normally, a circular saw is a powered saw that uses a toothed or abrasive disc set or blade to cut different materials by a rotary motion spinning around an arbor. Similarly, a hole saw and ring saw also use a rotary motion but are different from a circular saw. To be precise, circular sawing machines may also be loosely used for the blade itself. Circular sawing machines were invented in the late 18th century and were in common use in sawmills in the United States by the middle of the 19th century due to the growth of industry over agricultural sectors in the states then.
