It is a non traditional machining process in which no physical tool is used. Electron beam machining is the process is done by high velocity electrons developed in the electron gun.

It is similar to the electron beam welding machine.

Electron beam machining construction and working. 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. In this article you will know about electron beam machining. Electron beam machining is invented by kh steiger wald in the year 1952 in germany. Components and working of ebm electron beam machining is a kind of machining process by using high velocity electron beam. 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. This will generate high heat energy and melts and vaporize metal from work piece. By converting the electrons kinetic energy into heat energy and helps to melt the metal to do work on it. When the electron beam impact on the surface of work material the high kinetic energy of the electron converted in to thermal energy it is then melt and finally evaporate the metal. Electron beam machining is same as laser beam machining process in which except laser high speed electron beam impinges on work piece. Ebm equipment consists of the following units. The above figure shows the schematic diagram of a typical construction of electron beam machining equipment. Ebm can be used for very precise cutting or boring of a wide variety of metals. In ebm electrons are accelerated to high velocity as half of the light speed then it is impinged to work material surface. 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. This whole process takes place in vacuum chamber.
