Why Do You Need A CNC Press Brake

What Are Press Brakes?

Press brakes are machines that form lengths of sheet metal. These sheets are typically used in manufacturing, industrial applications, or as components for other devices. Most press brakes are rated by their capacity to press metal and their overall bending length; this is expressed in numbers (e.g., total PPI, or pounds of pressure per inch). They come in many forms and often are equipped with tooling and add-ons designed to create highly customized components. Press brakes fall into two main categories: mechanical and hydraulic. In the next sections, we’ll break down the difference and explain the prominent features of each style.

 

Types of Bending

There are two ways press brakes can bend metal. The first is called bottom bending because the ram will press the metal to the bottom of the die. Bottom bending results in highly accurate bends and relies less on the press brake machine itself. The downside is each tool is they're made to create one specific bend, so you’ll need to purchase a new one for every angle you want to make. Air bending leaves an air pocket between the ram and the bottom of the die. This allows the operator to accommodate for any spring back the material might provide. These types of dies only need to be changed if the material’s thickness is too much. Air bending’s drawback is the accuracy of the angle is affected by the material’s thickness, so the ram needs to be changed out accordingly.

 

CNC Press Brake vs Press Brake

A press brake is a machine used for bending sheet and plate material, most commonly sheet metal. It forms predetermined bends by clamping the workpiece between a matching punch and die and through force gaged in tonnage bends the metals.

The CNC press brake is much more specialized than press brakes. CNC brakes, short for Computer Numerically Controlled, can bend sheet metal work from just a few inches across to sections many feet long on the largest industrial machines. They have a fixed bottom bed with the V block tooling clamped in place and a top ram that travels under force with the V blade tool forcing the material to yield between the punch and die.  

With CNC a press brake the setup time is much faster as the controller calculates all the positions of the ram and backgage. It also can check for errors, can calculate the correct bend sequence and repeat the motion over and over again for production forming. With a manually operated press brake, the operator would have to reset the machine for every bend produced. With CNC, it is programmable so it makes switching to different bends, parts and even materials much faster.

How A CNC Press Brake Can Improve Your Business

CNC press brakes are widely used in comparison to the manual press brakes in most job shops and production environments. As we stated a CNC press brake is much easier to program and run today. 

Save Money

CNC Press Brakes can work much faster than other machines. Set up is much faster, they produce less waste, make right parts the first time and can make more products, faster. 

Flexible

CNC Press Brakes can be programmed to complete more than one task. You can set it up to do several jobs, pick the material needed, choose the pressure required and you can do it all in the language of your choice. From forming to punching, hemming and louvers too a CNC Press brake can do much more than just bend.
