Bending is a manufacturing process that produces a V-shape, U-shape, or channel shape along a straight axis in ductile materials, most commonly sheet metal. Commonly used equipment include box and pan brakes, brake presses, and other specialized machine presses.
In Bending we have two type of bending as below:
Hydraulic Bending:
All the technically superior and perfectly engineered instruments are found to consume less electricity and are even found having minimum maintenance. Mostly due to the rear cylinders, the system is responsible for consuming lower pressure along with the compact cylinders. The machines with these types of superior quality are found having power to fight against fatigue failure and the machines have a capacity of better rigidity as well as load carrying capacity.
CNC Bending:
Computer numerically controlled (CNC) bending is a manufacturing process that is carried out by CNC press brakes (also known as CNC brake presses). These machines can bend sheet metal work from just a few mm across to sections many metres long on the largest industrial machines. CNC press brakes either have a fixed bottom bed with the V block tooling clamped in place and a top beam which travels under force with the V blade tools this is known as down forming. The opposite is an up forming machine with the bottom bend moving and the top beam fixed. Both process methods will produce the same sheet metal components and there are no restrictions to the design of your component to suit either machine.
