Advantages of laser cutting processing

- Feb 13, 2018 -

Compared with other thermal cutting methods, laser cutting is characterized by fast cutting speed and high quality.It is summarized in the following aspects.

(1)Good cutting quality.

Because the laser light spot is small, the energy density is high, the cutting speed is fast, so the laser cutting can obtain the better cutting quality.

The laser cutting incisions are narrow and narrow, and the cutting edges are parallel and perpendicular to the surface. The size accuracy of the cutting parts can be up to + 0.05mm.

The surface is clean and beautiful, the surface roughness is only a few tens of microns, even laser cutting can be used as the last step, without machining, the parts can be used directly.

 after laser cutting, heat affected zone width is small, near the kerf width material performance is hardly affected, and the workpiece deformation is small, high cutting precision, good kerf geometry, slitting rectangular cross-section shapes appear more rules.The comparison of laser cutting, oxyacetylene cutting and plasma cutting is shown in table 1, and the cutting material is 6.2mm thick low carbon steel plate.

(2)The cutting efficiency is high.

Due to the laser transmission characteristics, the laser cutting machine is usually equipped with multiple CNC workstations, and the whole cutting process can be achieved in all CNC.In operation, the cutting of different shape parts can be applied only by changing the nc program, which can be cut in two dimensions and can be cut in three dimensions.

(3)The cutting speed is fast.

The cutting speed can reach 600cm/min with a laser cutting 2mm thick with power of 1200W.Cutting 5mm thick polypropylene resin plate with a cutting speed of 1200cm/min.The material does not need to be clamped in the laser cutting, which can save the tooling and the auxiliary time of upper and lower material.

(4)Non-contact cutting.

Cutting torch during laser cutting has no contact with the workpiece and no tool wear.The machining of parts with different shapes does not require replacement of the "cutter". Only the output parameters of the laser can be changed.The laser cutting process has low noise, small vibration and no pollution.

(5)There are many kinds of material cutting materials.

Compared with oxyacetylene cutting and plasma cutting, there are many kinds of laser cutting materials, including metal, non-metal, metal base and non-metal matrix composites, leather, wood and fiber.However, for different materials, due to their own thermal physical properties and different absorption rate of laser, different laser cutting adaptability is shown.
