How Does the Tube Mill Work?
A tube mill is a machine used to manufacture high quality precision products. This mill is one of the most important machinery in a variety of manufacturing applications, including precision paper making, metal working, metal casting, stamping and extrusion work. It is an energy-efficient machine with automatic feeders and heat exchangers. This type of machine is commonly used for precision surface machining and sheet metalworking.
Tube Mill: is fine-tuned, curved-shape machines that are fine-tuned to operate at a given speed (see Figure 2). The length of the strip that is being formed is set using a dial or a slider (a fixed integral element) in the feed position. Diameters of the flat or circular products being made are set as a result of the operating speeds of the different stages of the forming operation, as a function of the speed change of the forming rollers. In a typical tube mill the work piece to be formed rolls on a slide, which is moved by manually or electronically controlled rollers. A continuous loop of a metallic ribbon is then fed through the tube mill, from the work point to the feed position.
The work piece to be formed is fed through a series of cylindrical tubes or sheets of plastic materials which have been precisely ground. This process of manual grading or rotating abrasives in the work piece provides a smooth, rounded edge. The size of the abrasive disks can be varied according to the requirements of the customer. After the product has been passed through the tube mill, it is passed through a suitable die making it into a blank. The blank is designed to be used as a substrate for the manufacture of the desired products.
Feeding the abrasive material and the die into the sheet metal strip will form the first sheet of the tube milling equipment. The working of the machine is started by feeding the work piece through the accumulator. The rotating or moving parts of the accumulator are made to spin by manual or electronic control, in a process called winding. The rotating action of the motor extracts the abrasive material from the tube blank and feeds it into the working portion of the strip.
When the sheet metal has been formed to the correct shape, the work piece is placed into a suitable slot, which has been drilled into the face of the accumulator. The blank must be tightly pressed into this slot, in order to obtain a snug fit. Once the entire equipment is in place, a series of vacuum cycles will insure that the components are well lubricated for continued operation. After a sufficient amount of cooling time, the tube blank will be removed, the welding equipment will be switched on, and a start of operation will occur. It is important to remember that the process of heating and cooling requires considerable attention, and must only be attempted by a trained technician.
In the welded forming process, the wire feeders are fed one end of the wire strip, while the other is drawn back toward the feed pipe. The distance between these two pipes will depend on the required width of the strip. This drawing back of the wire feeder prevents the formation of smoke rings around the welded portion of the strip. The welded tube mill can be used in a variety of applications, such as creating tubes of different thickness for cutting, trimming, and welding.
