Giuseppe Speroni talks about offset bending (Z bending): the flanges.
We know that sheet metal bending is a complex process, to be dealt with accuracy and care. In the previous article we began our analysis of offset bends: particular bends which require special tools to form two bends with a single stroke.

Giuseppe Speroni talks about offset bending (Z bending).
This article is going to focus on a really particular type of sheet metal bending: offset bending.

Eurostamp press brake tooling.
Sheet metal bending permanently deforms the material, and in order to do so, it is necessary to take account of many parameters (such as quality and elasticity of sheet metal, its thickness and relation with punch and die): combining all factors involved is rather complicated, and sometimes it is difficult to obtain the required result.

Giuseppe Speroni talks about radius bending.
Sheet metal bending is a process which can be extremely complex. There are several different types of bending, and therefore several different levels of difficulty in making them. Among all types of bending, the one that usually gives more problems is the so-called radius bending, in which the internal bend radius is far greater than the sheet metal thickness.

How to bend sheet metal without scratches.
Sheet metal bending is a really delicate process and for this, it requires a lot of care and attention in order to avoid damaging the workpiece. Sometimes, working in haste or for a lack of attention, the sheet metal surface might be compromised by scratches or marks.

Punch tip radius and air bending.
In the previous article, we introduced the concept of punch tip radius. We talked about it in relation to the earlier kinds of bending: coining and bottoming. Let's now talk about the punch tip radius in relation to the most used kind of bending nowadays: air bending.

A focus on punches: why using different tip radii?
In the wide range of press brake tools, you can find several punches with similar profiles and dimensions, but they all differ in one aspect: the dimensions of the punch tip radius.

5 best practices to speed up tooling setup times.
Speed is a fundamental factor for productivity. For every minute that is not used in production, some money is lost.

Reasons that might damage punches.
The previous article focused on the maximum capacity of punches. We mentioned that when tonnage exceeds the maximum allowable tonnage per meter of a tool, the tool gets damaged. Such damages can include deformations - already taken care of in the previous article - or breakage.

How to determine the maximum capacity of punches.
The maximum load is the maximum allowable tonnage at which tools can be used without getting damaged. By "damages" we usually mean permanent deformation or breakage.
