Metal laser cutting machine is realized by using the high power density energy generated after laser focusing.
Its use of precision ball screw transmission mechanism, optimization of numerical control system control,
can meet the precision parts processing, and stable dynamic performance, sustainable work for a long time,
so in metal cutting, much attention. Metal cutting precision can affect the cutting process,
so how to control the metal laser cutting machine in use? Constant good laser xiaobian take you to see.
1, laser melting cutting does not need to make the metal completely vaporized, the required energy is only 1/10 of the vaporized cutting.
2, laser vaporization cutting material vaporization heat is generally very large,
so laser vaporization cutting requires a lot of power and power density metal laser cutting machine.
3, laser oxygen cutting reaction produces a lot of heat, so the energy required by laser oxygen cutting is only 1/2 of the melting cutting,
and the cutting speed is far greater than laser vaporization cutting and melting cutting.
4, laser scribing and control fracture, laser scribing is the use of high energy density laser scanning on the surface of brittle materials,
so that the material is heated to evaporate a small groove, and then apply a certain pressure,
brittle materials will crack along the small groove.
Controlled fracture is the use of steep temperature distributions generated during laser grooving to generate
local thermal stress in the brittle material, causing the material to break along the small grooves.
Compared with the traditional plate processing method, laser cutting has the advantages of high cutting quality
(narrow incision width, small heat affected zone, smooth incision), high cutting speed, high flexibility
(can be cut arbitrary shape), wide material adaptability.
