Laser Cutting Kerf Steel

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. Laser cutting as it is obvious from the name is a cutting technique in which a laser is used to cut through a material the laser finds a lot of use because of its precision. 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.

Laser cutting machine is a kind of equipment that can partially replace traditional metal cutting method.

Laser cutting kerf steel. 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. The automatic focusing height follower developed by kern laser systems is one of the key elements for optimal metal cutting. 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. Typical kerf width for 1 2 thick c s.

Each cutting process removes a different amount of material or kerf. Kerf for every process is different. Heating up too large of an area or having too much. In laser cutting how the laser beam assist gas and material interact determines the quality of cut.

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. It comes largely down to the laser s cutting kerf. This is known as the laser kerf and ranges from 0 08mm 1mm depending on the material type and other conditional factors. In recent years optical fiber laser cutting machine has been widely used to make metal laser cutting more convenient and efficient.

After slowing down and changing the assist gas pressure to accommodate the operator finds an even larger burr. The metal cutting option allows for accurate cutting of sheet metals like stainless steel mild steel aluminum copper and brass. Laser fusion cutting and ablative laser cutting. The laser burns away a portion of material when it cuts through.

It has the characteristics of fast cutting speed and high cutting quality. Laser cutting produces a kerf of around 0 3 mm this value is the smallest comparing it to the other techniques in this article. Heating up too large of an area or having too much. 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.

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. Broadly speaking laser cutting can be divided into two types. Here dross forms as molten material solidifies before it can be evacuated from the kerf.

In contrast ablative laser cutting removes material layer by layer using. Although above c0 45mm is only experienced when cutting thicker foams. The following are typical cut or kerf widths resulting from laser cutting process.
