Vital Rules to bear in mind When Deciding upon Press Brakes

At the choice time of press brakes, many contemplate it as a minor accessory in metal forming and don’t pay enough attention. As a matter of fact, press brakes have transformed into multiaxis, high-precision machines with enhanced features. But only the tooling touches the part while bending.

There are lots of important features needed to attain high-performance bending. Hence, regardless which tool you want to choose it is important that it meets at the very least several requirements. Here are a few important items to consider while choosing press brakes.

High Precision:
It is important that the press brake provides high precision work. And for that, Its tolerance should be within 0.0004-inch range. With this particular rangeĀ press brake, you will be able to attain part accuracy without any shimming and other tweaks. Amada Press brake parts will provide you with the required high precision work.

Segmented sections

It allows constructing of various lengths out of several pre-cut pieces. The tiny pieces are safer and simple to handle.

Self-retaining installation

With the ram up, you ought to be able to easily load the tools. It is important that the tool holding system should hold multiple pieces in position until you apply the clamping pressure.


As you apply the clamping pressure, punches will be mechanically pulled up to the position. It would eliminate the requirement to punch to the die throughout the setup.

Front Loading

It is important to have the ability to install tools from the front end of the machine. It would shorten the setup process as you’d no further need to invest time pushing tools from the finish of the press brake. Generally, it would eliminate the requirement for forklifts and overhead cranes.

Standard sizes

Various elements like safety devices, back gauge heights, and front arm support remain at a regular position & are constructed with the exact same height. Consequently, you can add off-the-shelf pieces and make sure that they match with existing tools.

There are lots of high-quality tools are constructed in line with the metric standards. So, you must enter details to find the correct tool.

Die Selection

To be able to get the value for your cash, it is important to decide on the very least level of lower dies which cover the metal thicknesses which your shop forms.

Punch Selection

For some applications in press brakes, in the event that you include high-tensile material, the workpiece might tend to crease, crack as well as split in two as you use common industry bending standards. Hence, narrow tip exerts force on the bend line. And after combining that with a narrow V-die opening, the forces rise even more. In challenging applications, when material thickness is above 0.5 in, it is important to consult your material supplier on the acclaimed punch tip radius.

Minimum Flange Length

The most important aspect to bear in mind when you choose your V dies may be the flange length. Many sheet metal designers save metal by specifying a flange which can be too short just like a 0.5-in. To be able to attain an ideal bending results, it is important to truly have a flange which can be at the very least 0.77in.

Punch Height

When forming three and four sized boxes, it is important to keep the punch height in mind. In some cases, short punches could form three-sided boxes if the formed side can hang off the side of press brake during the last bend. Hence, whenever forming four-sided boxes, it is important to decide on a punch which can be tall enough to span the box height diagonally.
