What Is A Tube Mill?
In the classic economic sense, a tube mill, also known as a rolled mill, is a type of automated welded roller mold system; but not every automated welded roller mold system is really a tube mill, anymore. Many tube mills are fine-tuned for use in other purposes, such as the manufacture of fine metal products. Tube milled products such as tubes are most often used in components such as valves, pumps and frames for airplane seats (Figure 2). Tube milled products are also used for forming rolled parts such as necking brackets and gaskets (Figures 3 and 4), in which the tube can be precisely stamped into the right diameter and length, for use in making precise bearings that fit tightly.
Unlike the conventional tumbler or press grinding system, tube mills generally do not require any sort of shielding to operate. They are ideal for forming tubes and gauges to precision tolerances, and because they use direct gas-powered laser or electric energy rather than steam pressure, produce much less pollution. It is generally accepted that the best way to perform tumblers and gauges is by using them on MIG welding equipment. But, because these types of welds are very difficult to see when welding, many manufacturers have started building tumbler and gauges that are mounted on non-magnetic surfaces, such as aluminum cases (Figures 5 and 6), stainless steel (Figures 7 and 8) and brazing (Figures 9 and 10). These non-magnetic mounting surfaces provide the user with an excellent view of the tube mill as it operates.
There are two common methods for tube mill forming; wet forming and dry-forming. Wet-forming means that the tube mill is loaded into a chuck, and the work piece is held in place by clamps or by gravity, and the tube is formed around the work piece by welding. The work piece is usually a circular one, because it is easier to control the diameter of a round object than an elongated one, which makes the turning radius and the overall diameter of the weld circle greater. In the wet-forming method, the power is applied directly to the metal and it is the metal that is formed instead of the workpiece. Dry-forming involves a cold-forming method that uses chemical feeders to feed material into the tumbler at a predetermined rate, resulting in the formation of metal clumps.
The basic operation of the tumbler and tube milling machines is quite simple. The user inserts the work piece into the machine. An air clamp holds the workpiece in place. Laser or electric energy is then fed through a welding initiator, which activates the arc, heating up the welding rods and welding the round product to the desired diameter range. After cooling down, this produces the desired thickness and diameter of the weld.
Tube milling machines are available in different types and are suitable for many applications. Depending on the type of work to be performed, the tumbler and tube milling machine may have different features and capabilities. For example, if you need to produce thicker and more detailed welds, the machine can be equipped with either vertical or horizontal roll stands. In addition, they can also be used for TIG (tig welding) welding and MIG (metal inert gas) welding.
There are several different manufacturers of tube mills. The best ones provide users with the best quality and meet all their customers’ needs. They also have to be easy to operate, durable, safe and versatile. Tube milling machines with precision cutting tools, CNC pulse engraving and automatic feed adjustment are also offered by some manufacturers. With so many makes and models, there is certainly a TIG, MIG, Tungsten Carbide, or ABS tube mill that will meet your business’ needs.
