Bending machine (manufacturing)

Those machines are able to bend single pieces as well as small batches with the same precision and efficiency as series-produced parts in an economical way.

The basic machine consists of a CNC-operated side stop, a work bench, and software for programming and operating.

Its modular construction offers an affordable entry into the bending technology, because after an initial investment the machine can be customized and extended later without any conversion.

For producing single pieces as well as small batches with the same precision and efficiency as series-produced parts, a spring back compensation is helpful.

A bending accuracy of +/- 0.2° starting from the first work piece is achieved due to calculated spring back compensation and the use of electronic tools.

The computer then calculates the required final stroke and spring back of every bend is compensated regardless of material type.

This method allows the pre-selection of the stroke of the bending ram in mm and therefore the immersion depth of the punch into the prism.

Programming is done on a PC equipped with dedicated software, which is part of the machine or connected to an external workstation.

The software automatically calculates the flat length of each part being bent and determines the exact position of the side stop.

A lot of organizational effort and interface management is saved, if the CNC bending machine is connected to the previous and subsequent process.

If a part is bended, in most cases a prior process was inserting holes to mount it in an assembly group.
