Accuracy Of Electron Beam Machining

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. Electron beam machining is a process in which high velocity electrons are concentrated into a narrow beam with a very high planar power density.

For more than 4 decades acceleron has been recognized as the industrys leading resource for electron beam and laser welding drilling and cutting services.

Accuracy of electron beam machining. Electron beam machining can be used to accurately cut or bore a wide variety of metals. 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. Electron beam machining is same as laser beam machining process in which except laser high speed electron beam impinges on work piece. The beam cross section is then focused and directed toward the work piece creating heat and vaporizing the material. By providing a unique analysis position corresponding to each depth etched more accurate profiles can be obtained since electron beam effects are reduced and the actual depths etched can be measured. Acceleron is the largest privately owned electron beam laser service company in north america. 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. This will generate high heat energy and melts and vaporize metal from work piece. Ebm can be used for very accurate cutting or boring of a wide variety of metals. From the annular bias grid the electron produced by the cathode is attracted towards the anode and gradually its velocity increases. 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. 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. 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 ebm first the electron is generated by the cathode and an annular biased grid does not allows the electron to diverge. As electron beam machining is grouped under the thermal category it is natural to have thermal damages as part of the result.

Ebm can be used for very precise cutting or boring of a wide variety of metals. This whole process takes place in vacuum chamber. Working of electron beam machining. This is why machining fragile and brittle materials is obtainable using this method. Electron beam machining does not apply any cutting force on the workpiece thus very simple work holding is required. It is mostly used to drill holes in any shape.
