Sheet Metal Bending Machine

Sheet Metal Bending Machine


Metal Bending Machine is a forming machine tool.Its purpose is to assemble a bend on a workpiece. A bends is manufactured by using a bending tool during a linear or rotating move. The detailed classification can be done with the help of the kinematics.

Metal bending machine included som type due to different metal bending types, mainly including CNC bending machine and Universal  bending machine.

CNC bending machines are developed for high flexibility and low setup times. 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.


Universal bending machines consists of a basic machine that can be adjusted with little effort and used for a variety of metai sheet bends. A simple plug-in system supports quick and easy exchange of tools.

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. That means the basic machine delivers a bending stroke, and the tool determines the kind of bending.


In the case of sheet metal  bending tools they are classified by the kind of generated bends. They can be constructed to adjust the bending angle by reference, stroke measurement or angle measurement.

CNC bending machines usually abstain from a reference part. They grant a high bending accuracy starting with the first work piece.


For U-bends where tight and narrow bends are necessary, the bending former is replaced by a bending mandrel. A bending mandrel has a narrow geometry.

Offset bending tools are used to assemble two bends with a small distance between in one step.

Edge bending tools are used if the bending axis is placed parallel to the tight side of the work piece. Tools for bending on edge may include electronic angular measurement allowing a high bending accuracy.

Torsion tools are able to rotate the workpiece on the longitudinal axis. Alternatives are complex assembly groups with standard bends
