电子束是一种能量转换效率很高的工具，基本上不受金属类型的影响。非真空电子束的高功率密度使其成为广泛应用的非真空电子束焊接和新型高速刀具的优良能源。将介绍德国汉诺威莱布尼茨大学材料科学研究所NVEB小组在非真空电子束切割(NVEBC)领域取得的进展。文中将介绍用传统的吹气射流进行熔融切割的实验结果，以及利用工件下方局部低真空产生的吸力的一种新的有前途的切割工艺。极高的切割速度，例如，对于2.5英寸厚的不锈钢，可实现18.5米/分钟的切割速度，从而产生高质量的刃口，这使得这种方法成为新的NVEB应用的重大发展。NVEB切割和后续焊接可以在一台整机上完成，实现了快速高效的孪生工艺。
The electron beam is a tool with high energy conversion efficiency which is by and large independent of the type of metal. Its high power density qualifies the nonvacuum electron beam as an outstanding energy source for the widely used nonvacuum electron beam (NVEB) welding as well as for a new high-speed cutting tool. Advances realised by the NVEB group at the Institute of Materials Science of Leibniz University of Hannover (Germany) in the field of nonvacuum electron beam cutting (NVEBC) will be presented. Experimental results for melt cutting with conventional blow gas jets will be presented as well as a new promising cutting process using the suction created by a local low vacuum underneath the work piece. Extremely high cutting speeds such as 18.5 m/min for 2.5 mm thick stainless steel producing high-quality edges render this method a significant development for new NVEB applications. NVEB cutting and subsequent welding can be done on one integral machine realising a fast and efficient twin process.
