Brief：Using the results of the laser cutting activity on the artifacts may be neat incision, or on the contrary, rough edges or burnt. |
Using the results of the laser cutting activity on the artifacts may be neat incision, or on the contrary, rough edges or burnt. Secco tai specialized is engaged in laser cutting machine research for six years, through continuous exploration, research, practice, summed up the impact cutting quality is the most important factor: the microstructure of alloy composition, materials, surface quality, surface roughness, surface treatment, beam reflection, thermal conductivity, melting point, hot melt, gasification temperature.
Alloy composition
Alloy elements to a certain extent, affects the strength of the material, proportion, weldability, oxidation resistance and acid. Carbon content is higher, the more difficult it is to cut (carbon 0.8% according to the critical value).
Basic material microstructure
Generally speaking, of material particles of the thinner, the quality of the cutting edge, the better.
The surface quality and roughness
If you have any rust area or surface oxide layer, then the outline of cutting will be irregular and appear many damaged point. If you want to cut corrugated plate, the choice of the maximum thickness of cutting parameters.
Surface treatment
The most common focus of surface treatment of galvanized, galvanized, painting, anodize or covering layer of plastic film. Treated with zinc plate easy to hang slag in edge; For paint plate, cutting quality depends on the composition of coating products.
Beam reflection
How beam in workpiece surface reflection depends on the basic material, surface roughness and processing. Some aluminum alloy, copper, brass and stainless steel plate has the characteristics of high reflectivity. When cutting the material, pay special attention to adjust the focus position.
Thermal conductivity
Welding, low thermal conductivity of materials, compared with high thermal conductivity material, needs less power.
Heat affected zone
Flame cutting and laser fusion cutting edge area material variation leads to cut materials.
When processing low carbon steel or anaerobic steel quenching of heat affected zone; For high carbon steel, there will be a marginal area hardening phenomenon; Hard rolling for aluminum alloy, heat affected zone and even a little Microsoft than the rest. |
