Dünnscheren

Dünnscheren, also known as slitting shears or coil slitting machines, are industrial machines used to cut wide rolls of sheet metal into narrower strips. This process, known as slitting, is essential for many manufacturing operations, allowing metal to be supplied in custom widths for specific applications. Dünnscheren typically consist of a series of circular blades mounted on arbors. The wide coil of metal is fed between these rotating blades, which shear the material to the desired widths.

The precision of the cut is crucial, and the machines are designed to achieve tight tolerances. Dünnscheren can handle a variety of metal types, including steel, aluminum, and copper, and can process coils of varying thickness and width. The slitting lines are often automated, with tension control systems and scrap winders to ensure efficient and continuous operation.

The resulting narrower strips, called slit coils or blanks, are then used in downstream processes such as stamping, forming, and welding to create a wide range of products, from automotive parts and appliances to roofing and packaging materials. The ability to precisely control the width of metal feedstock via Dünnscheren is a fundamental aspect of modern metal fabrication.
