在黃金加工過程中，經(jīng)常遇到鋁板加工。其中一個問題是鋁板是否可以用激光切割?答案是肯定的。
　　Aluminum plate processing is often encountered in gold processing. One of the questions is whether the aluminium plate can be cut by laser. The answer is yes.
　　幾年前，激光切割機(jī)可以切割鋁板，當(dāng)工人拿油墨在鋁板上(據(jù)說是因為鋁板反射系數(shù)高，怕反射激光)，切割時，激光的參數(shù)很難調(diào)整。當(dāng)時只能切割1毫米厚的鋁板。經(jīng)過經(jīng)驗的積累，鋁板切口非常光滑，沒有掛渣。
　　A few years ago, laser cutting machines could cut aluminium plates. When workers took ink on the aluminium plates (said to be because of the high reflection coefficient of the aluminium plates, afraid of reflecting laser), it was difficult to adjust the parameters of the laser. At that time, only 1 mm thick aluminium plate could be cut. Through the accumulation of experience, the incision of aluminum plate is very smooth and there is no slag hanging.

　　激光切割鋁板也看看激光發(fā)生器的力量,較能降低到16毫米厚6000 w, 4500 w減少到12毫米,但只有處理費用高,因為,這是一個高反光材料,激光切割是利用高功率密度激光的焦點工件,使輻照材料迅速融化,蒸發(fā)和消融或達(dá)到燃點,同時借助高速氣流和束流同軸吹塑材料，從而實現(xiàn)工件的開槽。
　　Laser cutting of aluminium sheet can also see the power of laser generator, which can be reduced to 16 millimeter thick 6000 w, 4500 w to 12 millimeter, but only the processing cost is high, because this is a high reflective material. Laser cutting is to use high power density laser focus workpiece, so that the irradiated material quickly melts, evaporates and melts or reaches the ignition point, at the same time, with the help of. High-speed airflow and beam coaxial blow moulding material, thereby realizing the grooving of the workpiece.

　　激光切割鋁板的切割表面是否和其他材料一樣光滑?

　　Is the cutting surface of laser cutting aluminium plate as smooth as other materials?
　　鋁板的切割也很光滑，鋁板只是一種高反射材料，這就需要一個大型的激光發(fā)生器。切割氣體和其他材料一樣，是用氮氣切割的，不會使表面不光滑。
　　The cutting of aluminium sheet is very smooth. Aluminum sheet is only a kind of high reflective material, which requires a large laser generator. Cutting gas, like other materials, is cut with nitrogen, which will not make the surface not smooth.
　　鋁板采用激光切割特點:
　　The characteristics of laser cutting for aluminium sheet are as follows:
　　1. 細(xì)切削縫:激光切割鋁板的切削縫一般為0.1mm-0.2mm
　　1. Fine Cutting Seam: Laser Cutting Aluminum Plate Cutting Seam is generally 0.1mm-0.2mm
　　2、切割表面光滑:激光切割鋁板切割表面無毛刺和掛渣。
　　2. Smooth cutting surface: laser cutting aluminum plate cutting surface without burrs and slag.
　　3.熱變形小:激光加工的激光切割縫薄，速度快，能量集中，所以傳遞到切割材料上的熱量小，材料引起的變形很小。
　　3. Small thermal deformation: the laser cutting slit is thin, fast and energy is concentrated, so the heat transferred to the cutting material is small, and the deformation caused by the material is very small.
　　4、節(jié)省材料:激光加工采用計算機(jī)編程，激光設(shè)備可對不同形狀的鋁板工件進(jìn)行材料切割，提高鋁板材料的利用率，節(jié)省大量材料成本。
　　4. Save material: Laser processing is programmed by computer. Laser equipment can cut different shapes of aluminium sheet workpieces, improve the utilization rate of aluminium sheet materials and save a lot of material costs.
　　5. 鋁板的切割厚度主要取決于激光發(fā)生器的功率大小。一般較大厚度6000W可以切割到16mm, 4500W可以切割到12mm。
　　5. The cutting thickness of aluminium plate mainly depends on the power of laser generator. Generally, the maximum thickness of 6000W can be cut to 16 mm, and 4500W can be cut to 12 mm.
　　鋁板屬于高反射材料，激光損傷很大!
　　Aluminum plate belongs to high reflection material, laser damage is very big!
　　一般不建議客戶使用光纖激光切割機(jī)來切割鋁板，盡可能少!
　　Generally, customers are not advised to use optical fiber laser cutting machine to cut aluminum plate, as little as possible!
　　一束激光就是幾十萬，所造成的損失是不值得的!
　　A laser beam is hundreds of thousands of dollars, the damage is not worth it!
　　結(jié)論:根據(jù)我的經(jīng)驗，co2激光機(jī)價格相對較低，激光發(fā)生器功率較大。注意，正如我上面所說的，在鋁板上涂上一層吸收光線的黑色可以防止反射光線燒壞鏡頭或激光頭。至于光纖激光器或不切割鋁板，則不值得損失，選擇其他方式加工鋁板。
　　Conclusion: according to my experience, the price of CO2 laser is relatively low and the power of laser generator is relatively high. Note that, as I said above, a layer of absorbed light black on the aluminium plate prevents the reflected light from burning the lens or laser head. As for fiber laser or non-cutting aluminium sheet, it is not worth losing. We choose other ways to process aluminium sheet.
　　激光切割鋁板注意事項:鋁板屬于高反射材料，會對激光造成很大的損傷，所以應(yīng)盡量少使用。建議對6mm以下的鋁板進(jìn)行數(shù)控沖床加工，6mm以上的鋁板采用水切削加工。
　　Cautions for laser cutting of aluminium sheet: aluminium sheet belongs to high reflective material, which will cause great damage to laser, so it should be used as little as possible. It is suggested that the aluminium sheet less than 6 mm be processed by numerical control punching machine and the aluminium sheet more than 6 mm be processed by water cutting.
