Electron gun in electron beam machining. A beam of electrons is emitted from the electron gun which is a triod consisting of. A cathode is a hot tungsten filament 25000c emitting high ve potential electrons. A nanocoulombmeter in combination with a faraday cup can be used to detect and measure the beams emitted from electron gun and ion guns. In this article you will know about electron beam machining. A high energy electron beam hits a target stimulating emission of x rays. Ebm can be used for very precise cutting or boring of a wide variety of metals. Electron beam gun the basic functions of an electron beam gun are to generate electrons from the high voltage supply attached at the cathode accelerate them to a sufficiently high velocity and direct the beam to the workpiece through a small spot. By converting the electrons kinetic energy into heat energy and helps to melt the metal to do work on it. Electron beam machining is invented by kh steiger wald in the year 1952 in germany. Working principle of electron beam machining. Electron guns are also used in medical applications to produce x rays using a linac linear accelerator. The grid cup negatively based on the filament. Electron beam machining is process in which high velocity electrons are concentrated in a narrow beam and then directed towards the workpiece for machining. This whole process takes place in vacuum chamber. It is a non traditional machining process in which no physical tool is used.

This feature is not available right now. Electron beam machining is the process is done by high velocity electrons developed in the electron gun. Electron beam machining is same as laser beam machining process in which except laser high speed electron beam impinges on work piece. This will generate high heat energy and melts and vaporize metal from work piece. Surface finish is better and kerf width is narrower than those for other thermal. Mechanism of material removal in electron beam machining c. 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 an electron beam machining the electrons strike the. When this high velocity electron strikes the workpiece it melts and vaporizes the material from the workpiece. In this video we have explained working of electron beam machining process we have seen the working principle equipments used.
