What is an electron beam machining?
Electron beam machining (EBM) is a term metallurgy that describes the process in which concentrated heat from electron beam is used for metal melting. The process usually takes place inside the vacuum, thus protecting the metal from the outer atmosphere as a flow in traditional welding processes. The process is used in various applications, including welding, annealing and metal removal.
Due to the complexity and load of the equipment, compared to the equipment for machining laser beam, this type of machining did not become a key stone of industry and production. While electron beam processes create a smoother finish and more accurate results than other machining processes, the need for specially trained operators and inherent devices cause electron beams to make electron beams unsuitable for most industries. This equipment is used primarily in the electronic industry that uses this technology to etch the UNIT microprocessor and other miniaturized technologie.
Electron beam machining can cut many different types of metal and metal alloys. The electron beam is highly focused, thus producing a thinner area of KERF or cut than many other thermal methods. The process also produces a smoother surface on cut surfaces that requires little, if at all, the surface surface for the final product.
Usually the application of welding this process creates highly concentrated heat in the vacuum chamber. This vacuum serves as a flow for joint protection when the heat of the beam machining process melts two pieces of metal and any filler, allowing these pieces to join. The welding process of machining the electron beam in this way is limited by the size of the vacuum chamber. To solve this restriction, this type of machining is sometimes used in the form of an open -air, called nevakuum electron beam of mbools, but this significantly reduces process and thickness thicknessfor metals that can be effectively processed.
The third application of electron beam machining is annealing of metal and metal alloys by heat. The metal parts to be processed are located inside the vacuum chamber and then bombed with high speed electrons. When these electrons get to the metal, part warms up to its melting point and then allow to cool. This heating and cooling process softens the metal to prepare it for further metal processing.
