In this process the material is removed with the help of a high velocity travelling at half the speed of light ie. In the electron beam machinings process a high velocity focused beam of electrons is used to remove the metal from the workpiece.

Electron Beam Machining EBM Introduction Principle of EBM.
Electron beam machining. Electron beam machining is same as laser beam machining process in which except laser high speed electron beam impinges on work piece. Electron beam machining is a thermal process that is used to remove metals during the machining process. Electron beam Machining is a process in which a high velocity of electrons are concentrated through a narrow beam and is then directed towards the workpiece such that the material removal takes place by melting and vaporizing from the surface of the workpiece.
The history of electron beam technology began with the experiments by physicists Hittorf and Crookes. Types of EBM Process. Hello Everyone Welcome To Engineers Academy Topics Covered.
It is mostly used to drill holes in any shape. The following two methods are used in the EBM process. Electron Beam Machining EBM Ion Beam Machining IBM EBM is a thermal energy based advanced machining process.
In this Video we have explained Working of Electron Beam Machining process We have seen the. Highly cost in installation and Maintenance. The electron beam polishing equipment technology is brought forward and its characteristic is explained because general processing method cant obtain preferable machining efficiency and.
Surface finish is better and kerf width is narrower in comparison to other thermal-cutting processes. Meaning of Electron Beam Machining EBM. When this high velocity electron strikes the workpiece it melts and vaporizes the material from the workpiece.
160000 kmsec focused stream of electrons which are focused magnetically upon a very small area. Machining inside the vacuum chamber. When the high-velocity beam of electrons strikes the workpiece its kinetic energy is converted into.
Electron Beam Machining is process in which high velocity electrons are concentrated in a narrow beam and then directed towards the workpiece for machining. Electron Beam Machining EBM is a machining process in which material is removed from the workpiece by focusing a beam of high-velocity electrons towards the workpiece. In electric beam machining electrical energy is used to generate electrons with high energy.
Electron-Beam Machining EBM can be used for very accurate cutting or boring of a variety of metals. Metalic and non metalic material without restrictions. Electron beam machining can provide holes of diameter from 100 µm to 2 mm with a depth up to 15 mm.
The electron beams in EBM-Machining equipment are generated in an electron beam gun. IBM is one mechanical or kinetic energy momentum transfer based advanced machining process. 1952 is seen as the dawn of electron beam technology.
This whole process takes place in vacuum chamber. A concentrated beam of high velocity electrons is used to supply heat for removing material from workpiece. EBM as we say is an unconventional machining process that uses a high speed electron stream or beam that impinges on the workpiece and transfer all their kinetic energy to the work material producing intense heat causing swift melting and vapori.
This will generate high heat energy and melts and vaporize metal from work piece. The source of energy in electron beam machining is high velocity electrons. High speed electron injected in the work piece.
What had to be laboriously worked out at that time is taken for granted today. Almost all materials can be machined using this process ranging from metals such as steel stainless steel titanium and nickel super alloys and aluminium to non-. Karl-Heinz Steigerwald built the first electron beam processing machine.
