Stainless steel metal laser cutting machine cutting process
XT Metal Laser Cutting Machine
Stainless steel is a common industrial steel with high hardness, strong corrosion resistance, and one of the strongest steel in the construction industry. When it comes to stainless steel cutting, we have to mention the metal laser cutting machine.
Due to the special nature of stainless steel, its main processing methods for cold processing and hot processing of two types of moulding. Stainless steel cutting cold processing methods are mainly saw cutting, wire cutting, water cutting, shearing cutting, punching, drilling and other ways, the quality of its moulding is generally high, but low efficiency, often not able to meet the needs of mass production. Thermal processing methods cutting methods mainly plasma cutting and laser cutting two methods. Laser cutting speed, high efficiency, cutting quality is much better than plasma.
Such as XTLASER’s tube and plate integrated laser cutting machine principle, is the laser beam irradiated to the surface of the stainless steel workpiece, the laser releases energy to make the stainless steel workpiece irradiated by the local surface melting and evaporation, in order to achieve the purpose of cutting and engraving, with high precision, fast cutting, not limited to the cutting pattern limitations, automatic nesting to save materials, smooth incision, low processing costs and other characteristics, will gradually improve or Replace the traditional cutting process equipment.
If the laser cutting process parameters are strictly controlled in the process, the good corrosion resistance of such materials can be maintained. The most important process parameters affecting the quality of stainless steel cutting is the cutting speed, laser power, air pressure and so on. Specific problems and debugging methods are as follows:
Produce dot-drop-shaped fine regular burrs
Possible causes
(1) The focus is too low
(2) Feed rate is too high
Solution
(1) Raise the focal point.
(2) Reduce the feed rate.
Long irregular burrs on both sides, discolouration of plate surface.
Possible causes
(1) Feed rate is too low.
(2) Focus too high
(3) Air pressure too low
(4) Material is too hot.
Solution
(1) Increase the feed rate
(2) Lower the focus
(3) Increase air pressure
(4) Cool the material
Long irregular burr only on one side of the cutting edge.
Possible causes
(1)Nozzle not centred
(2) Focus too high
(3) Air pressure too low
(4) Speed too low
Solution
(1) Align the nozzle
(2) Lower the focus
(3) Increase air pressure
(4) Increase speed
Material is discharged from the top
Possible causes (1) Power too low (2) Feed rate too large (3) Air pressure too high Solution
Press the pause button immediately to prevent the slag from splashing onto the focusing mirror, increase the power, reduce the feed rate, reduce the air pressure.
Cutting edge yellowing how to do?
Yellowing of cutting edge
Possible causes
Oxygen impurities in the nitrogen gas
Solution
Use good quality, high purity nitrogen.
