Electron Beam Machining
Electron-beam machining is a process where high-velocity electrons concentrated into a narrow beam with very high planar power density in the focus cross-section are directed toward the work piece, creating heat and vaporizing the material. Electron beam machining can be used for very accurate cutting or boring of a wide variety of metals. Surface finish is better and kerf width is narrower than those for other thermal cutting processes, but because the equipment acquisition costs are very high, the use of this technology is therefore limited economically.

Famous quotes containing the word beam:
“It was at that moment, just after Krug had fallen through the bottom of a confused dream and sat up on the straw with a gasp—and just before his reality, his remembered hideous misfortune could pounce upon him—it was then that I felt a pang of pity for Adam and slid towards him along an inclined beam of pale light—causing instantaneous madness, but at least saving him from the senseless agony of his logical fate.”
—Vladimir Nabokov (1899–1977)
