GILDEMEISTER put forward a kind to be based on supersonic technology those who be used at processing work of hard fragile data is brand-new method. This method applies to pair of pottery and porcelain, glass, hard alloy, silicon, black lead, stick the treatment that receives agent and stainless steel. Pharmacy industry, optical industry and auto industry, increase increasingly to the demand of spare parts of high load capacity with the department of a few industry of etc. In this one trend, people was used numerous so called " high-powered data " , for example pottery and porcelain, glass, hard alloy. This kind of material has very good character on one hand (weight is light, chemical stability and thermal stability are good, anti-corrosive wait) , but on the other hand their strong fragile character makes traditional treatment method (for example: Treatment of cutting tool of grinding, diamond) the expenses that processes a method to be hard to machine or using a convention rises. Be based on this kind of setting, technology of people application ultrasonic implemented quanta transition technology in manufacturing industry. The basis of Hermann Sauer Inc. that is located in Ck of ü of Stipshausen Im Hunsr the 30 experience that come in supersonic treatment domain for years, developed new technology of a kind of supersonic treatment, Ultrasonic. After from November 1, 2001 GILDEMEISTER group joins High-tech-Schmiede, this company has become 10 big cutting machine tools of European to produce one of business. According to the design program of Ultrasonic, ultrasonic machines a process to bring certain influence to cutting, enchase the mill that diamond particle is made, auger, grind cutting tool the frequency with 20kHz (namely every second 20000) cut work. Below the help of ultrasonic, even if the hardest work also can use lesser strength and higher feed power to undertake cutting is machined. When the treatment method that uses a convention at present processes hard brittleness data, need cent undertakes for much talk working procedure, waste time, and treatment cost is higher, cause huge loss (because treatment cutting tool is mixed,be caused by the attrition between treatment workpiece) . And use ultrasonic treatment, can have immediate treatment according to the target, a lot of advantages have in machining a process: , compare with conventional treatment, ultrasonic treatment can be at most inside 5 faces the treatment that has high quality. , the surface after treatment is bright and clean degree can achieve Ra<0.

2? M. , because used integral formula from adaptive control (ADR) harmonics controls a method (ACC) , rose to machine the security of the process. , when accurate bore, bore diameter is the smallest can amount to 0.

3mm. , because strength and thermic load are small, be helpful for protecting workpiece and cutting tool. , the diamond cutting tool that can grind a knife by oneself can make sure taller cutting efficiency prolongs service life. When undertaking ultrasonic machines a process, need believes a high frequency report date translate into quantity of a mechanical motion. Pass the amplitude of vibration of enlarge of a booster next. Theoretic, uses diamond cutting tool is in 20kHz (every second 20000 pulse) will contract first below pulse motion, appear subsequently outspread. When reaching amplitude or outspread maximum, the diamond particle that secures together with cutting tool touchs the workpiece surface that needs treatment. Workpiece material by broken for tiny and drossy. At the same time cutting tool rotates with the 3000 rotate speed to 4000rpm, machine precision to make workpiece is achieved on one hand, rotate to keep clear of on the other hand of the workpiece material below the cutting inside the area drossy, these are drossy and final sweep from inside workshop with clean water. If choose grinding treatment, need uses a large number of clear water to rinse, if choose mill or the treatment that get, need to undertake cooling to main shaft. Measure except amplitude and use control beyond, diamond cutting tool and secure the diamond particle on cutting tool to produce very big effect to machining the efficiency of the process and quality to also be met. The influence basically depends on the hardness of diamond blade and the dimension with atomic diamond, depend on especially cutting tool bears the weight of connective is chemical between part and cutting material, mechanical character, character of this one join needs with the treatment of Ultrasonic process photograph agrees. Beyond the rod that removes Ultrasonic, stick receive material to also can happen to contract first again outspread phenomenon. Because this is choosing to stick,want to assure: When diamond particle outspread arrive when apogee, still maintain with cutting tool between stick receive enough and firm. It is certain to still need to have additionally flexible, when making proper diamond particle is bumped unapt break off from cutting tool, and undertake cutting inside big range only. Cut in all these numerous Chan Ren was formed in the process, the cutting tool when because this is using diamond cutting tool,undertaking cutting is machined can grind a knife automatically. Can assure in the whole service life of cutting tool very tall and the cutting efficiency that keeps changeless. Another main factor in the link that Ultrasonic machines is to pass the cutting tool of special design to wear (already won patent) . An awl whorl can realize reliable appearance join and force join, make sure good vibration delivers a gender between main shaft and workpiece. The structure of this kind of special design is machining the security of main shaft of card of process middleman and guarantor, make on the baseplate that fore-and-aft vibration won't deliver main shaft bearing and by bearing passes a machine tool (similar an one-way check valve) . The place with the successful technique of Ultrasonic depends on machining the efficiency of the process not just, more important is to be able to assure to be mixed to machine quality by the treatment precision of treatment workpiece. The account that Ultrasonic technology can be accepted by potential user suffers the effect of two elements: Of the security that machines a process and treatment process but repeatability, made sure Ultrasonic technology is in all sorts of production environments thereby all applicable. The unit of computerized numerical control of Ultrasonic machine tool has the intelligence of all sorts of types to control algorithm, real time undertakes the process is monitored, give out to control regulated quantity suitably, for example: Amplitude, feed and rotate speed, will make immediateness identifying according to lag error, with avoiding cutting tool break off. The function that Ultrasonic machine tool comes to a few years in real work proves (three-shift system, often use a circumstance to fall) afore-mentioned measure are effective. In use, can with from adaptive control means (ADR) or acoustics control means (ACC) composition controls a system two kinds. When be used with ADR couplet, the staff guage on the machine tool has the function that monitor, because first-rate feed can come true in this treatment. The working kind that faces a machine tool with ADR is different, ACC is received or monitor the acoustics process signal that workpiece issues. If the exterior treatment demand to workpiece is high, need to use ACC to control fashion. No matter be ADR or ACC, it is to physics parameter undertakes metrical. Intelligence changes control algorithm to take no account of occasional case and before experience. Use ACC and ADR combination, can machine the effect with first-rate flexibility implementation. Beginning to machine level for example, give out by ADR as far as possible big feed, and in evening of exterior precision work, automatic switch controls fashion for the acoustics signal of ACC. The Ultrasonic series that ULTRASONIC supersonic company offers above all has two kinds of kinds, x axis 350mm and X axis 500mm. The DECKEL MAHO company that is located in Sauer supplied the main part of the machine for the machine tool of two kinds of afore-mentioned types, sauer undertakes assembly to the component of these Ultraschal machine tools, for example: Dynamo of Ultraschal main shaft, Ultraschall, oscillatory sensor and diamond cutting tool. Outside removing standard component, ULTRASONIC supersonic company returns complement to supply a series of special purpose accessory of Ultrasonic series machine tool, the manufacturing order that processes with Yu Wei for example.
