A variety of metal materials laser cutting process description (1) aluminum and alloys. Aluminum cutting belong to melt steel cutting mechanism, the use of auxiliary gas is mainly used to blow away the molten product from the cutting area, usually achieve better quality section. For some aluminum, it should pay attention to the prevention of inter-kerf surface crystal micro cracks. (2) Copper and alloys. Copper (copper) due to the high reflectivity, can not be cut with a substantially CO2 laser beam. Brass (copper alloy) stainless steel products with higher laser power, the auxiliary gas using air or oxygen, a thinner sheet can be cut. (3) and titanium alloys. Titanium can be well focused laser beam coupling transformation heat, auxiliary gas using oxygen chemical reaction intense, cutting speed, but it is easy to generate an oxide layer trimming, careless also cause over-burning. For the sake of security, the use of air as an auxiliary gas is better, in order to ensure the cutting quality. Aircraft industry commonly used titanium laser cutting quality is better, although there is a little slit at the bottom of sticky residue, but it is easy to remove. Chongqing Chongqing stainless steel machining difficult reasons consistent processing factories have the same feeling: Stainless difficult to process. In fact, nothing more than the following reasons: 1: Processing hardness resulting in rapid tool wear, and very difficult to chip. 2: The low thermal conductivity caused shavings edge of plastic deformation and rapid tool wear. 3: BUE easily lead to fines emblem pieces left on the cutting edge of the pin, and cause adverse machined surface. 4: chemical relationship between the tool and the workpiece caused by work hardening and low thermal conductivity materials processing, not only likely to cause unusual wear, but will the tool chipping and abnormal rupture. Existing processing problems than solutions as follows: A: Use tools with high thermal conductivity of the stainless steel door, B: the sharp edges of the cutting edge: a wide stainless steel embossed plate chipbreakers edge band, can reduce the cutting pressure, so that we can good control chip. C: optimal cutting conditions: inappropriate processing conditions will reduce tool life. D: Select the appropriate tool: stainless steel knives should have a very good toughness, adhesion strength and cutting edge coating films have relatively high.
