This will generate high heat energy and melts and vaporize metal from work piece. This whole process takes place in vacuum chamber.

Ebm can be used for very precise cutting or boring of a wide variety of metals.
Theory of electron beam machining. Ebw is often performed under vacuum conditions to prevent dissipation of the electron beam. Electron beam welding ebw is a fusion welding process in which a beam of high velocity electrons is applied to two materials to be joined. However while the sem uses a focused beam of electrons to image the sample in. Electron beam machining is the metal removal process by a high velocity focussed stream of electrons which heats melts and vaporizes the work material at the point of bombardment. The electron beam polishing equipment technology is brought forward and its characteristic is explained because general processing method cant obtain preferable machining efficiency and product quality. It is mostly used to drill holes in any shape. The theory of electronic beam machining is explained in detail which include electronic beam come into being. Electron beam machining is same as laser beam machining process in which except laser high speed electron beam impinges on work piece. The workpieces melt and flow together as the kinetic energy of the electrons is transformed into heat upon impact. Focused ion beam also known as fib is a technique used particularly in the semiconductor industry materials science and increasingly in the biological field for site specific analysis deposition and ablation of materialsa fib setup is a scientific instrument that resembles a scanning electron microscope sem. In this post you learn what is electron beam machining how its done with its working principle advantages of ebm accuracy and limitation of electron beam machining. Electron beam machining ebm is a process where high velocity electrons concentrated into a narrow beam are directed toward the work piece creating heat and vaporizing the material.
