Tube Mills makes durable pipe and tubing by taking a continuous length of material and continually roll shaping it until the exposed edges of the straight strip meet together in a common weld area. Often stainless steel tubing and pipe are manufacturing by arc welding using either the TIG or plasma arc processes. They are designed to handle heavy duty work including oil refractory materials, scientific experiments, chemical analysis, and manufacturing products for the laboratory or industrial environment. These custom fabrication shops can also fabricate stainless steel pipe, polyethylene, and polypropylene. Tube Mills is run by computer numerical controlled (CNC) machines, which allow for precise customization of cutting systems and pipe works for almost any project.
Tube milling machines range from those that utilize belt grinding to those that use ball bearings. Grinding tubes can be manually turned by hand or electronically. Ball bearing tube mills operate in either wet or dry environments and grind non-ferrous tubes.
The type of grinding that takes place will depend on the diameter of the material being printed as well as its stress level. Typically, the higher the diameter of the material, the less force needed to grind the material into a usable diameter. High load situations may require more force for a faster action than low load circumstances. Grinding rates are measured in rpm’s or rotations per minute. Tube milling machines usually have a variable control system to control grinding speeds and the ability to hold the current settings while the machine is running.
Some tube mills require electrical power to operate. These machines are usually set up as stand alone units that plug into an electric current source to allow them to function independently of a power grid. Tube rollers use a standard ball assembly to create a large cross sectional of pipes where the abrasive material is applied. Tube welding machines are used to weld pipe sections as well as fabricate other products such as seams and other reinforcing structural components.
Tube milling machines are designed to maintain a constant diameter range during repetitive machining operations. This allows designers to utilize the full capabilities of available resources without having to scale production down if the finished product requires a different size. Tube forming operations typically start at the start point with a high speed blanking process that provides a crisp edge for the final product. After the initial blanking is performed, the machine is capable of repeating the operation at a predetermined rpm based on the load capacity of the work piece. The high precision nature of this machining method means that any error made during the forming process will have a significant impact on the finished product.
There are a number of different advantages to using a tube mill. These machines offer a high level of repeatability when it comes to producing custom parts because they use a simple, one-step cutting system. They also provide manufacturers with the ability to incorporate pre-cut electrodes into their overall design, which eliminates the need to purchase pre-mounted electrodes or custom wire forms. Because of these benefits, many manufacturers are able to design and build complete power supplies, wire harnesses, generators, battery packs, isolators, power motors and more with this type of welding process alone.
