Process characteristics

   Laser cutting is compared with other thermal cutting methods, the general characteristic is that the cutting speed is fast and the quality is high. Specifically summarized as the following aspects

advantage:

  1, good cutting quality

  Due to the small laser spot, high energy density, and high cutting speed, laser cutting can achieve better cutting quality.

  1 The laser cutting incision is narrow and 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.

  2 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 laser cutting, the width of heat-affected zone is very small, and the performance of the material near the slit is hardly affected. The deformation of the workpiece is small, the cutting accuracy is high, the geometry of the slit is good, and the cross-section shape of the slit is relatively regular. Rectangles.

  2, high cutting efficiency

  Due to the transmission characteristics of the laser, laser cutting machines are generally equipped with multiple numerically controlled tables, and the entire 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.

  3, cutting speed

  Laser cutting of 2mm thick low carbon steel plate with a power of 1200W, the cutting speed can reach 600cm/min; cut 5mm thick polypropylene resin plate, the cutting speed can reach 1200cm/min. The material does not need to be clamped during laser cutting, which can save the fixture and save the auxiliary time for loading and unloading.

  4, non-contact cutting

  The cutting torch is not in contact with the workpiece during laser cutting 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 no pollution.

  5, cutting material types

  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. However, different materials have different laser cutting suitability due to their own thermophysical properties and different laser absorption rates.
