To very deep and very narrow planar welding line when, electron beam solders the technology is a very reliable craft. It can be out of shape angle and the influence with a few ideal blame decreases transverse and contractive quantity and other the smallest. German electron beam, the field develops in current electron beam, it is the most advanced and reliable. Wave guest electron beam, as the famous lead person inside the industry, the platform with was offerred better for the academic communication that electron beam solders and draw lessons from. The application that applied electron beam solders was covered receive from filmy solder one-time solder the workpiece of 200mm. In addition it still can solder different metallic stuff and the combinative other people of these material. Value can face the problem that how carries the design program with right choice to save cost in order to achieve when designing mechanical part, electron beam is having very large latent capacity on this. Because solder rate is very rapid, the big lot that electron beam technology makes a field in electronic product and car reflects the productivity that gave height in production. Be opposite aerospace, a few products of shipbuilding or railroad industry undertake sheet treatment and technology of the electron beam when small lot is produced also are reflected the accuracy that gave it and but repeatability, because this kind of craft contains advanced electron,be measured and electric control technology, because it is product line of this pair of automation,one optimizes premise. Our advantage: Solder steadily technology, economy, dependability. Applied domain electron beam solders the technology is applied at almost all domains, compare tall solder replace Wu what can achieve a level with technical requirement. Auto industry: Undertake with high economy large quantities of quantities are produced, for example: System of transmission of whole motive force (engine, main transfer machinery) (graph 1) . Graph 1 aerospace industry: Machine a few technologies to ask to have the part of special purpose high, the component that is like helicopter (graph 2) or satellitic fuel box. Graph 2 the sources of energy and electronic industry: The product of material of a few contacts is like products of copper of big batch treatment and other breaker (graph 3) . Graph 3 railroad, shipbuilding and medical industry: The join of on the safe side, the ouch that is like train of German high speed (graph 4) the embedded content with applicable human body (graph 5) . Graph 4nextpage pursues 5 machines equipment makes and food industry: The combines content product of small lot and the steel with goods of large quantities of quantity treatment stainless steel and different other. Can solder through electron beam the workpiece that hefts 50 tons. Research and development: Can realize a design complex, cost is high and the treatment of the product of high demand, the material of these products is tungsten, the special material such as platinic gold. The meeting when process electron beam solders is machining area to produce necessary energy through the electron (the high pressure that passes 60-150kV is quickened) . Bundle drifting formation is all the time in vacuum. Solder to also undertake in vacuum, some equipment are below atmosphere environment implementation solders. When the electron bumps workpiece to go up, major kinetic energy is changed into heat energy, undertake soldering. Energy density is not in 0.

1mm was achieved inside the focal diameter limits to 2mm 105 to 109W/cm2. In efficient when electron beam solders can achieve and laser beam welding receives almost same energy density (laser energy utilization rate: 3-14% , utilization rate of electron beam energy: About 70% ) . In the electron beam when high speed solders can solder goes out extremely deep and narrow welding line. Because dinky welding line width makes,be out of shape very small also. The part that electron beam is used at soldering to ask welding line is very fine, because electron beam is OK,be controlled accurately by electric field deflexion. Accessible welding line deepness is in 0.

3mm arrives between 300mm (aluminous) , 150mm (steel) . High energy density makes electron beam OK solder all metals, include a few easy fused metals, and undertake soldering coming true mixture assorted to different material, be like steel and bronze. Electron beam solders equipment often is produced with the batch at the drive disk assembly in auto industry (basically be Japan and Germany) . Besides simple, the treatment task of valence cheap, other comes from aerospace, the component of railroad traffic and food industry also can solder with electron beam. Concerned deepness solders more information of the effect. When the electron bumps raw material, they release decelerate its kinetic energy (the majority turns for heat energy) . The result that deepness solders produces by the process below: Become what the electron catchs to bump workpiece surface some a little bit when, quantity of heat can produce in this bits. When energy density exceeds 106W/cm2, the material that center of the focus that be called handles begins to fuse evaporate. Arise from inside vapour capillary, capillary be surrounded by fused material. Make so bundle stream permeate more thorough, continue to fuse the archaism material all round. If work look has shift to electron beam, can be fused in the material before electron beam so, after that along steam capillary flow and subsequently solidify. Graph 6 deepness melt is OK solder goes out very narrow and the welding line that deepness exceeds 100mm (the deepness that what if pursue,show 6 times is aluminium solders (150mm) . It can achieve a 50:1deep wide than. The craft parameter of electron beam is OK by accurate control. All parameter can be measured as electricity unit and controlled. The measurement of electricity parameter compared with fiber-optic the measurement with optical parameter is simpler. The control method of innovation and the union that CNC controls a system are used, for material treatment developed the possibility with new more. In view of accurate and adjustable quality, make the bandit of all application benefit of electron beam shallow: Pass handy and reliable measurement, below OK and exact record all bundle of drifting adjustment parameter and easily reproduction. The feedback in whole closed-loop control is feasible, because this is in those who machine positional electron beam to adjust already can it is OK also that the hand is moved full automatic come true, return at the same time easily the hand is moved hold accuse. The aperture that when soldering, allows: The biggest permission aperture is to solder the 5 ％ of deepness, but it is at most 0.

3mm. Apply every time should acknowledge error. Larger crack needs to solder complementary makings. These two kinds of cases come from technical angle and commercial angle normally say, do not hope to happen. Design: Electron beam craft is design engineer, processing brings extremely tall freedom to spend when join problem, carry the option that optimizes to material, lead you to enter cost managing model production. What because use electron beam,undertake soldering assuring is low not just be out of shape and high accuracy. Graph 7 in addition the application that electron beam sheds many bundles still can overcome other welder art confine: When solder, if workpiece does not allow too hot, or the welding line deepness that is a requirement is very big, and must assure to be inside a very little tolerancepublic errand scope, right now electron beam photograph revealed an advantage to laser system. Because a lot of workpiece are OK,become, can make so cheap material replaced expensive stuff to become a possibility. Solder well the design can avoid, the treatment cutting bits with very high cost and pickling undertake in the other position of weldment. Material: Extremely high energy density makes electron beam OK solder all material, the metal that includes to fuse extremely easily and pass different data solder the production that realizes mixture, like steel and bronze (the depth that the graph shows the bronze that is a model and steel 8 times solders (20mm) . Graph 8 use electron beam technology, wave guest company can solder reliably Die Casting aluminous spare parts. The odd part of the detached medium that is chained as gas in material interior can drop off slowly, the gas that can avoid to make a person afraid so is volatile expand. Below a lot of circumstances, the heat that can pass proper displacement will control the formation of the hot tearing of alloy of high strenth nickel. Much bath technology: Use the much bath technology of wave guest, can solder to amount to 60 welding line at most at the same time. The solder of welding line of the axial on pinion has put through 3 bath technology comes true (solder with 3 bath technology pinion) . This kind of means was reduced be out of shape, still shortened the weld time of 2/3. Still can abandon in addition high tool technology and spot welding. In the radial in this case and axial the error of homocentric sex is less than 1/500. CNC Milling CNC Machining
