Pipe drawing and drawing machines are machine tools used in the metalworking industry to bring pipes or bars to a specific size and shape. A tube drawing machine is used to draw the tube through a die to refine and flatten it. The pipe is inserted into a die, and then what is called a "mandrel" is inserted into the pipe to support it. The tube is then pulled through the die to refine and smooth it. This process can be repeated to further refine the tube and reduce its wall thickness. A tube drawing machine, on the other hand, is used to shape the tube into a specific form by drawing it through a die that imposes a new shape on the tube. Tube drawing machines are particularly useful for bending tubes into complex shapes and angles that cannot be achieved by conventional bending. Both types of machines are often used in tube and bar manufacturing to ensure high precision and repeatability. Tube drawing and drawing-in machines are often equipped with CNC controls to ensure precise and automated processes.
