Basics

Sheet-metal parts showing uneven surfaces lead to poor quality of the final products. In addition these parts cause higher costs due to subsequent processing and assembling. Unevenness of the parts results from processing methods such as shearing, stamping, nibbling, laser or plasma cutting, hardening and coating caused by changes of internal stresses of the component.

Range of parts

• Parts with a thickness from 0.5 mm to 8 mm, a width of up to 500 mm and up to 5,000 mm in length
• Steel, copper, aluminium, titanium, special alloys, and bimetals up to a yield point of 600 N/mm² at normal temperature and up to a hardness of 48 HRC
• Flat parts and parts with uneven surface
• Parts for device engineering, machine, aircraft and automotive industry
• Parts for electrical engineering and the construction industry
• Saws and cutting tools
• Weaving lamella, housing parts, perforated plates

Roller Levelling

The highest degree of surface evenness can be achieved and internal stresses are reduced remarkably when levelling the parts with a precision leveller. The individually driven levelling rollers level the workpieces through alternate bending. The upper and lower rows of rollers are arranged offset to each other, forming a wedge-shaped profile which opens in running direction. The strongest bending of the material occurs at the inlet where the material is formed until it reaches its plastic state. At the outlet the workpiece is only formed to its elastic state leaving the machine with an even surface.
