Laser cutting machine principle - cutting characteristics

Date:2018-06-15

Laser cutting advantages:

Advantage I - high efficiency
Due to the laser transmission characteristics, laser cutting machines are generally equipped with multiple CNC workbenches, and the whole cutting process can be fully realized with numerical control. In operation, only by changing the numerical control program, it is possible to apply the cutting of different shapes of parts, both for two-dimensional cutting and for three-dimensional cutting.

Advantage II - Fast

The power of 1200W laser cutting 2mm thick low carbon steel plate, cutting speed up to 600cm/min; cutting 5mm thick polypropylene resin board, cutting speed up to 1200cm/min. Materials do not need to be clamped during laser cutting.

Advantage III - Good Cutting Quality

A: The laser cutting incision is narrow, the slits are parallel on both sides and perpendicular to the surface, and the dimensional accuracy of the cut parts can reach ±0.05 mm.

Two: The cutting surface is smooth and beautiful, the surface roughness is only a few tens of microns, and even laser cutting can be used as the last process without mechanical processing. Components can be used directly.

3. After the material is laser cut, the width of the heat-affected zone is very small, and the performance of the material near the kerf is also almost unaffected, and the workpiece deformation is small, the cutting accuracy is high, the geometry of the kerf is good, and the cross-section shape of the kerf is relatively Regular rectangles. The comparison of laser cutting, oxyacetylene cutting, and plasma cutting methods is shown in Table 1. The cutting material was a 6.2 mm thick low carbon steel plate.

Advantage IV - cutting non-contact

During laser cutting, there is no direct contact between the torch and the workpiece, and there is no tool wear. To machine parts of different shapes, there is no need to replace the "tool", just change the output parameters of the laser. The laser cutting process has low noise, little vibration and little pollution.

Advantage V - more cutable materials

Compared with oxyacetylene cutting and plasma cutting, there are many types of laser cutting materials, including metal, non-metal, metal-based and non-metal-based composite materials, leather, wood, and fibers.
