Norck: Precision Sheet Metal Cutting – Solutions for Your Fabrication Needs

Norck delivers expert sheet metal cutting services, empowering businesses across industrial, architectural, automotive, and other sectors to achieve clean cuts, complex profiles, and cost-effective fabrication outcomes.

Sheet metal cutting designs multiple technics in which sheet metal is cut to form simple or complex shapes. The commonly used technic is shearing which is applied using an inclined blade.

Other popular techniques are laser cutting and waterjet cutting, which can produce complicated shapes. These two techniques are made with computer-controlled machines (CNC) to control the cutting head.

Sheet metal parts should follow specific design rules to be cut properly. Norck offers engineering services that will help you validate your designs.

Most of the sheet metal cutting operations are performed as cold. Norck offers sheet metal cutting and forming processes as described below:

•  Blanking / Punching:
Blanking and punching are cutting processes of a workpiece from a sheet metal coil using a press (DIE). This process is mainly used in mass production fields such as automotive. The significant variables are the punching force, the die and punch materials, and the number of parts produced per minute.

A scrap is removed from the sheet metal to produce the workpiece (blank) in blanking. On the contrary, in punching, a workpiece is punched from the sheet metal, and the left is scrap. Norck will help you nest your parts to get the most cost-effective process.

In both processes, clearance is a significant factor in cutting. It is the distance between the cutting edges(die and punch), and it depends on the elasticity and thickness of the material. With higher clearance, rollover and burns can occur. With a lower clearance, a secondary shear can occur. Norck has an expert team that will guarantee you a perfect cut each time.

•  Shearing: It is slicing a flat sheet of metal using an inclined blade. Shearing can be done manually using a set of traditional tooling or semi-automatically using a die and a punch. It is preferred to use shearing when making straight cuts, although it can be influenced by the formability of the sheet’s material and thickness. At Norck, we use blade types for each specific material to produce a clean cut with no visible burrs.

•  Laser cutting: Laser cutting is a thermal method used to obtain custom flat shapes of sheet metal. Laser cutting can cut through various materials, such as metals, and is used to cut almost any 2D shape. Accuracy is around ±0.0005inches (±0.01mm).

• Waterjet Cutting:  Waterjet Cutting is a method that uses a high-velocity jet stream to cut through most materials.Waterjet cuts through various materials such as metals, stones, glass, plastic, and composite materials. Accuracy is around ±0.0010inches (±0.03mm) for waterjet.

• Plasma Cutting:  Plasma cutting is a process that jets gas at high temperatures to cut through electrically conductive materials. Plasma can cut steel, stainless steel, aluminum, brass, and copper. It is widely used, from art and custom-made tools to aeronautic and automotive industries.
