Laser Cutting Kerf Steel

In contrast ablative laser cutting removes material layer by layer using.

Laser cutting kerf steel.

The metal cutting option allows for accurate cutting of sheet metals like stainless steel mild steel aluminum copper and brass. The laser burns away a portion of material when it cuts through. Here dross forms as molten material solidifies before it can be evacuated from the kerf. Cutting mild steel with a laser is balance of how much material is heated up with the laser beam and how much assist gas flows through the cut.

Heating up too small of an area or not having enough assist gas flow through the cut will result in the kerf width of the cut being too narrow. Laser cutting produces a kerf of around 0 3 mm this value is the smallest comparing it to the other techniques in this article. Kerf for every process is different. The width of laser cut or kerf and quality of the cut edges are effected by power of the laser laser beam pulses and the motion of the laser beam and work piece.

Typical kerf width for 1 2 thick c s. After slowing down and changing the assist gas pressure to accommodate the operator finds an even larger burr. In recent years optical fiber laser cutting machine has been widely used to make metal laser cutting more convenient and efficient. Laser cutting machine is a kind of equipment that can partially replace traditional metal cutting method.

Broadly speaking laser cutting can be divided into two types. The following are typical cut or kerf widths resulting from laser cutting process. Heating up too large of an area or having too much. It comes largely down to the laser s cutting kerf.

It has the characteristics of fast cutting speed and high cutting quality. Heating up too large of an area or having too much. Cutting mild steel with a laser is a balance of how much material is heated up with the laser beam and how much assist gas flows through the cut. In laser cutting how the laser beam assist gas and material interact determines the quality of cut.

Heating up too small of an area or not having enough assist gas flow through the cut will result in the kerf width of the cut being too narrow. A typical example shown here is for 1 2 thick mild steel. Laser fusion cutting involves melting material in a column and using a high pressure stream of gas to shear the molten material away leaving an open cut kerf. The more precise processes like waterjet and laser remove a smaller amount of kerf which is one of the reasons they can be more precise.

The automatic focusing height follower developed by kern laser systems is one of the key elements for optimal metal cutting. Although above c0 45mm is only experienced when cutting thicker foams. Each cutting process removes a different amount of material or kerf.
