          濟南激光切割時的功率要求是多少

            在濟南建材市場上,激光切割功率密度對切割速率有很大的影響,透鏡焦距的挑選是一個重要問題。光點大小和激光束聚焦后透鏡的焦距正相關。激光經短鏡頭焦距鏡片對焦后光斑尺寸不大,聚焦點處功率非常高,這會對原材料切割非常有幫助。

            In the Jinan building materials market, laser cutting power density has a significant impact on cutting speed, and the selection of lens focal length is an important issue. The size of the light spot is positively correlated with the focal length of the lens after the laser beam is focused. After focusing with a short lens focal length lens, the size of the laser spot is not large, and the power at the focal point is very high, which is very helpful for cutting raw materials.

            鏡頭焦距與工件表面的位置關系對確保切割品質至關重要。因為聚焦點處功率非常高,在很多情況下,切割時的部位僅僅在材料表面或稍低于表層。在所有鉆削環節中,確保聚焦點和工件位置關系不會改變是擁有平穩鉆削品質的重要條件。有時候因為制冷不太好,攝像鏡頭能被加溫,造成鏡頭焦距的改變,因此需要及時糾正鏡頭焦距部位。

            The relationship between the focal length of the lens and the position of the workpiece surface is crucial for ensuring cutting quality. Because the power at the focal point is very high, in many cases, the cutting area is only on the surface of the material or slightly below the surface. Ensuring that the relationship between the focal point and the workpiece position does not change is an important condition for achieving stable drilling quality in all drilling processes. Sometimes, due to poor cooling, the camera lens can be heated, causing changes in the focal length of the lens. Therefore, it is necessary to promptly correct the focal length of the lens.

            在大部分運用中,光線聚焦點被調整至噴頭的下方。噴頭與材料表面之間的距離一般在1.5mm前后。一般來說,原材料切割需要協助汽體。難題主要包括協助氣體類型和工作壓力。一般情況下,協助氣體噴涌方向和激光的噴出方位同樣,以保障鏡片不受污染,并吹跑切割區底部爐渣。針對非金屬材質和其他金屬復合材料,用壓縮氣體或稀有氣體消除熔融和蒸發的原材料,與此同時抑止切割區域內的過多點燃。

            In most applications, the focus of light is adjusted below the nozzle. The distance between the nozzle and the material surface is generally around 1.5mm. Generally speaking, the cutting of raw materials requires assistance with the vapor body. The main challenges include assisting with gas types and working pressure. In general, the direction of assisting gas injection is the same as the direction of laser injection to ensure that the lens is not contaminated and to blow away the slag at the bottom of the cutting area. For non-metallic materials and other metal composite materials, use compressed gas or rare gas to eliminate melting and evaporation of raw materials, while suppressing excessive ignition in the cutting area.

            對于大部分金屬激光切割,活性氣體(但凡是O2)與鋼水產生空氣氧化化學反應,可讓切割速率提升1/3-1/2。在確保協助汽體前提下,空氣壓力是一個非常重要的要素。快速切割薄料時,需要鋒面氣旋,以避免創口反面粘渣(粘到產品工件里的熱渣也會損傷切割邊沿)。當原材料薄厚提升或切割速率緩減時,應適當調整標準氣壓。為了避免塑膠刀口起霜,要用相對較低的標準氣壓切割。

            For most metal laser cutting, the active gas (usually O2) reacts with molten steel to form an air oxidation chemical reaction, which can increase the cutting rate by 1/3-1/2. Air pressure is a very important factor in ensuring the assistance of the steam body. When cutting thin materials quickly, a frontal cyclone is required to avoid slag sticking on the opposite side of the wound (hot slag sticking to the product workpiece can also damage the cutting edge). When the thickness of raw materials increases or the cutting rate slows down, the standard air pressure should be adjusted appropriately. To avoid frost on the plastic cutting edge, a relatively low standard air pressure should be used for cutting.
