Cutting with sheet metal cutters, slitting shears, and nibblers

To cut sheet metal, we can offer you sheet metal cutters, slitting shears, and nibblers.

Shear cutting process

Shear cutting process

The shear principle allows deformation of the material, but no material is lost in the form of scrap chips. When cutting with the sheet metal cutters ,the upper moving cutter blade moves against the fixed lower cutting table blade. This puts high tension on the material to be machined and creates what is known as a lead crack. With sheet metal cutters, the material is sheared off at a high cutting speed and the cutting table blade absorbs the entire shear force of the moving cutter blade.

Advantages

  • Excellent performance on curves
  • Quick, precise cutting
  • Long tool life
  • Chip-free cutting
  • Great cut quality

Slitting shears process

Slitting shears process

Deformation in the sheet is completely avoided with slitting shears. This is because slitting shears have two cutting inserts next to each other, unlike conventional shears. The blade makes a swivel movement in the shearing gap and cuts during the upward movement. The resulting sheared off chip rolls up in a spiral. We have developed a variety of slitting shear blades for different applications. A delicate, slim blade shape improves the performance on curves. A robust blade, on the other hand, is very suitable for straight coil cutting.

Advantages

  • Deformation-free cutting
  • Great cut quality
  • Quick working speed

Nibbling process

Nibbling is a cold process without heat influence. Unlike thermal and other mechanical processes, nibbling produces no dust emissions, gas emissions or smoke. The punched material comes out in the form of chips. The tools used are a punch and a die.

Nibbling is based on the principle of separating plate-shaped parts with punching strokes in quick succession. The punch nibbles a cutting track into the sheet with upward and downward movements. The die holder absorbs the entire punching force of the punch. They are therefore extremely robust and made of highly durable steels.

Nibbling process

Different punches

  • Up to 3.5 mm, hollow round punches are used. This allows you to turn the machines in place.
  • For 3.5 mm and above, rectangular punches are used. The narrow punch shape provides a high degree of maneuverability.

Advantages

  • Distortion-free and emission-free cutting
  • High cutting speed
  • Clear view of the work surface
  • Low feed force regardless of sheet thickness
