Electron Beam Micro Machining

An optical viewing system is required in order to allow the operator to see the work in order to position the beam. The deflecting coils allow the beam to have a range of movement of 12 mm.

Electron beam machining is same as laser beam machining process in which except laser high speed electron beam impinges on.

Electron beam micro machining. This property permits the fabrication of nanoscale patterns by using an eb sensitive polymer resist in a process called eb lithography ebl. Dimensions produced between greater than or equal to1mm and smaller than or equal to 999mm1. On this channel you can get education and knowledge for general issues and topics. In welders with electron beams of high enough power welds up to 300 mm deep can be realized. Yunitha ratnadilla tri adhi kusuma 11313560tk37951 electron beam machining a. 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. There are also welding machines in which the electron beam is brought out of vacuum into the atmosphere. 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. In micro electron beam devices components with dimensions in tenths of a millimeter can be precisely welded. Today we will learn about electron beam machining principle working equipments application advantages and disadvantages with its diagram. Ebm can be used for very precise cutting or boring of a wide variety of metals. Ion beam machining ibm ion beam machining or etching is generally a surface finishing process in which the material removal takes place by sputtering of ions. The electron beam can be controlled very accurately and machining tolerances of 0005 mm are possible. The process is different from electric discharge electron beam laser and plasma arc machining in that the process does not depend on heating of the workpiece to the point of evaporation. It is a non traditional machining process in which no physical tool is used.

Micromachining micro machining micromachining macro component but removal of material at micronano level. Micronano components and material removal is at micro level. Electron beam eb machining is a powerful method for micro and nanofabrication because the beam can be focused to a diameter of the order of a few nanometers. Electron beam micromachining it is a type of thermal micromachining. 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. Introduction electron beam machining is one of the examples of non conventional machining under the thermal process category along with laser beam machining electric discharge machining and plasma cutting.
