TRUMPF - Used Sheet metal processing machines

Sheet metal processing machines

Sheet metal processing machines manufacture sheets in the requested shape. The specialized equipment leads the tool and the part being machined. They are used in industry, trade and and during the manufacturing process of different tools.

A huge variety of different production possibilities for metal sheet

Sheet metal processing includes different production possibilities like punching, lasering, cutting, tilting, beding and mechanical installation. Metal processing machines are available with or without CNC controller. The CNC technology is able to transmit data to the workpiece. The programming software allows operators to check whether it is possible to bend the part.

Fields of application

Metal sheets can be used in many different areas for example in steel construction or in automotive industry. Furthermore, they can be applied for the construction of appliances, machines, rail vehicle, ships and pipelines.

Different applications require specific metal sheets and demand specific requirements for the material and size. Sheet metal processing machines can prepare metal sheets for their intended use. There is a wide range of metal processing machines for different production processes. With certain installations it is possible to realize operations in a quick and precise way.

Cutting

Flat sheets can be tailored to the need of individual sizes. There are different ways to cut the metal for example mechanical procedures like sawing, shears or water-jet cutter. Other suitable machines can be curling tongs, plasma cutting machines or laser cutting machines that work when exposed to heat energy.

Punching

The punching of metal sheets achieves precise results. This kind of sheet metal working requires specific tools to punch the flat parts in the desired shape. Punching machines are also available as combined laser-punching installations.

Folding machines

Metal sheets can be bent to get three-dimensional components. Folding press quipment is available with manual clamping and pneumatic clamping. Press brakes and embossing machines are suitable for the folding of metal plates. The folding of metal sheets requires special care. To achieve a plastic deformation, it is necessary to overstep the yield strength of the metal but not the tensile strength. Overstepping the tensile strength could damage the material. Heat can make it easier to deform thick metal sheets.

Round bending

Round bending causes the deformation of metal sheets. It is chipless and the metal sheet are not chopped. It`s suitable for cases where the sheet plate has to include a soft rounding. Round bending machines or roller rounding machines are the suitable machines for this task.

Milling and machining

The milling is often at the beginning of the manufacture. It helps to design the outline of the workpiece.

The milling machine has a rotating cutting tool which removes material of the workpiece. This process includes three advance directions and is able to create complex components.

Other sheet metal forming proceedings

Drilling and punching are also common processes for sheet metal forming. Moreover, it is possible to connect metal sheets through welding, hemming, soldering, rivets, bonding or screws. The type of metal decides which process is particularly suitable. The production types are also feasible through special sheet metal processing machines or sheet metal forming processes.
