The process of bending, is the mechanical process of physically shaping metal objects and pieces through physical means; the workpiece is manually reshaped without taking or removing material, and the size and shape of the object remain unchanged. In Euromac Bending Machines like the ones from https://www.cotswold-machinery-sales.co.uk/euromac/horizontal-bending-machines/digibend-tooling/, a mandrel is inserted into a work piece in order to apply bending loads. In metal bending machines, the workpiece has a mandrel plate, which is then extended to bend the object, with the help of a hydraulic cylinder. It can be used for bending all kinds of metals such as aluminum, stainless steel, brass, bronze, copper, and many others.
Another important fact about bending machines is that it uses force from a powerful motor-driven by electric or manual power to rotate the work piece at a definite angle. These machines are called rotating machines because the bending rod is attached to the motor which causes the rotation to the bending rod. This happens at very high speed, which makes bending very expensive in comparison to manual bending. In order to minimize the cost of bending the rod, some manufacturers make use of a second material which is the base material which is not made up of metal but can support the rotating rod while the work piece is bent.
Most people know the basic operation of bending machines. However, many people do not understand the details of the above mentioned process. For instance, when we talk of rotary-shaft bending, we should mention that these machines have a straight shaft which is supported by arches and grooves. There is a gear-and-wheel assembly present in the machine, which rotates the shaft at a predetermined angle, and it is located above the working surface. While bending cylindrical objects, facts about bending machines help us to understand that the most common forms of bending are counter-bend and bending.
