Electron beam machining can be used to accurately cut or bore a wide variety of metals.

Electron beam machining applications. Working principle 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. The full range of electron beam welded fabrications is incredibly diverse after all not many welding techniques can weld say steel that is 01mm thick or at the other extreme 300mm thick in a single pass. Electron beam machining is a process in which high velocity electrons are concentrated into a narrow beam with a very high planar power density. Electron beam machining is process in which high velocity electrons are concentrated in a narrow beam and then directed towards the workpiece for machining. Some examples of electron beam welded products are given below. The grid cup negatively based on the filament. The figure shows the principle of operation of electron beam machining. Through introduction of the principle and characteristics of electron beam machining technology the application status and application instance of electron beam in research of materials science and materials processing in recent years were introduced in detail. When this high velocity electron strikes the workpiece it melts and vaporizes the material from the workpiece. Weld cross sections of production parts will be shown to demonstrate obtainable weld shapes. The beam cross section is then focused and directed toward the work piece creating heat and vaporizing the material. This paper provides a technical overview of the unique features of the electron beam welding process including several applications. A cathode is a hot tungsten filament 25000c emitting high ve potential electrons. Ebm can be used for very precise cutting or boring of a wide variety of metals.

It produces monochromatic light which is in the form of an almost collimated beam that can be focussed optically on to very small spots of less than 0002 mm dia. Bi metal saw blades are produced in large numbers by electron beam. The research situation of the previous various electron beam machining methods and applications was discussed and the various. Electron beam machining does not apply any cutting force on the workpiece thus very simple work holding is required. This is all about electron beam machining principle working equipments application advantages and disadvantages with its diagram. A beam of electrons is emitted from the electron gun which is a triod consisting of. The laser is electromagnetic radiation. As electron beam machining is grouped under the thermal category it is natural to have thermal damages as part of the result. In this post you learn what is laser beam machining its working principle parts advantages applications and limitations. If you have any query regarding this article ask by commenting.
