High pressure is cooling (HPC) the technology processes medium application in aviation material

The part that cooling fluid uses when machining aviation spare parts is in those who experience certain level to evolve. The practice that job shops comes to for years is: Bear down on cooling fluid directly treatment area, use the data that cooling fluid processes to need especially. Now, high-pressured refrigeration technology can direct cooling fluid essence definitely treatment area, can gain a few new benefit. As to it of form a complete set brand-new of cutting tool concept roll out, high-pressured refrigeration technology has been on the numerical control machine tool of a lot of modernization use extensively. If extraordinary should apply cooling fluid effectively, show the result of extraordinary, use high-pressured eject refrigeration morely with respect to need, its discharge must enough big, efflux direction also wants correct. Use to cooling fluid flows or irrigate cooling fluid the practice to treatment area to cannot have satisfied need only merely. In addition, compare with groovy refrigeration, reasonable apply high pressure to cool (HPC) there can be remarkable distinction in the following respect: ① cuts bits to form; Of ② heat in metal cutting distributing; The caking property with ③ workpiece good on cutting blade stuff; ④ surface integrality; ⑤ cutting tool wears away. Promote competition ability thereby through improving the following target ceaselessly, these main treatment factors also are affecting production result accordingly: ① manufactures efficiency; Life of ② cutting tool; ③ cuts bits control and platoon bits; ④ spare parts machines quality. HPC is being machined commonly, the result when processing stainless steel and mild steel especially is right, do not pass pair of difficult treatment data (if titanium alloy and heat-resisting are super alloy) treatment showed more breathtaking result. The near future makes about a large number of research and development of HPC its are used more easily, more inviting also. Jetbreak system is leading innovation the concept in last centuries 80 time arrive 90 time, shanteweikekeleman developed Jetbreak of system of cooling fluid of the first high pressure. Consider to make clear, for slashing to machinability and requirement of field of the control that cut bits difficult treatment material, be as high as 100, 1000 cling to the one part that the cooling fluid efflux with extrahigh voltage, accurate direction has made cutting cutting tool. Cooling fluid efflux forces his to enter cut wedge of a hydraulic pressure is formed at the same time between bits and cutting blade, shortened so the osculatory length that cuts bits and cutting blade, dropped the temperature that machines area thereby. The effect with interesting another is cooling fluid eject those who shed meeting influence to cut bits is curly, improved the control that cut bits thereby, certain circumstance falls to still can bring about bits. Through using a few corresponding cutting tool that be not mark, jetbreak already became machinability difference and / or the good solution of material of the difficulty that break bits. Of cooling fluid pressure distributing and the dimension of cooling fluid nozzle is met very big to machining a result to arise impact. Pass the efflux parameter with distinct change, can achieve a different bits result, likely banding bits guides the way that wants to place improves the length that cuts bits even. Jetbreak had had a few actual application, in order to solve the problem that oil, aerospace and scroll encounter in bearing industry. But, jetbreak needs to deploy appropriative to be not mark knife handle, basically use on vertical lathe. A lot of contemporary machine tools contain HPC system of the standard to mark matchs or choose the pressure that match to be 70 to 100 cling to cooling system, this enough uses HPC system, can achieve excellent performance and treatment result. Such HPC also can more use at lathe of center of machining center, turning, vertical and much task machine tool widely. Standard equipment enough offers the cooling fluid channel that leads to efflux application area. A when high-pressured cooling fluid machines main base is modular cutting tool, it ensures through changing a knife to be on certain level quickly the machine tool stops engine loss not only the smallest, and offerred the channel that causes cooling fluid effectively to cutting blade reliably from the machine tool. Module type changes full Capto of coke of cutting tool system quickly is the development base of Jetbreak and CoroTurn HP of cutting tool of refrigeration of new-style standard high pressure. This system is ideal module type platform, its design was used inside cooling, also can apply to high-pressured refrigeration. Coke full Capto has made ISO standard, be secured by a lot of cutting tool and / or the place of numerical control machine tool that cutting tool rotates is chosen. The milling cutter that is used at HPC is contained inside cold passageway, can mix according to cutting tool type applicable applied circumstance provides corresponding spray head. Cooling fluid passageway and machine tool or other pump are linked together, in order to supply about 70 cling to the cooling fluid of pressure. At present this kind of cooling fluid is supplied already was applied extensively, the pressure that although involve,arrives is not in similar Jetbreak the superhigh pressure in such special application circumstance, but the enough inside the range that uses in its can be mixed in processability clear improvement is won on the result. This one concept made full use of to make much user job shops already some or the ability that will throw and resource. The HPCCoroTurn HP that Nextpage uses at turning is a kind of new-style standard coke that is used at turning HPC application concept of full Capto cutting tool. It can produce jet of parallel accurate cooling fluid, cut with be being mixed in bit hydraulic pressure wedge arises between bits, the influence cuts the temperature that bits is formed and flow and reduces treatment extent. Well and truly eject gives the spray head that approachs cutting blade installation efflux of high speed cooling fluid, force cut bits to leave bit surface to make cut bits cools and rupture to discharge bits with benefit into shorter length. Nozzle dimension of the standard is 1mm, also have 0.

6mm arrives 1.

2mm dimension can apply for be being optimized specificly. Had proved, although be in cooling fluid pressure is low to 10 cling to when, precision work of use HPC system includes steel, stainless steel, aluminium and titanium alloy and heat-resisting the Ren Ke such as super alloy gains the benefit that comparative. Besides the higher treatment security that brings by the better control that cut bits, HPC still can prolong cutting tool life apparently and have the latent capacity that uses taller cutting rate, through using HPC, can improve cutting tool life normally 50% . Rather he any element photographs are compared, cutting rate is older to cutting temperature and influence of cutting tool tatty. When machining titanium alloy, of the cutting speed after exceeding reasonable area add congress to bring about cutting tool life to shorten quickly. But feed increases below similar case, of cutting tool life shorten do not have so apparent. Accordingly, make the plan that has appeal more in order to improve metallic purify rate through changing feed. But, the addition of feed can produce greater cutting power for certain, the likelihood still can affect the control that cut bits, consequently use Gao Jin is not the plan that always is a kind of perfect to the quantity. By right of can use higher cutting rate but won't appear again at the same time common temperature lifts and loss of cutting tool life, HPC has the latent capacity that promotes treatment through raising cutting rate property. To according to ISO S kind material, can be in maintain identical cutting length while raise the cutting rate of 20% . Round turning also is a field that HPC can produce main effect inside, it conduces to ensure cut bits goodly to form, machining what difficult treatment material still can improve data when titanium alloy for example to cut function. Such, making higher treatment security and longer cutting tool life can be acquired when boring working procedure. Should use boring lever to machine relatively big and deep aperture, for example landing gear when the spare parts, the idea of module type cutting tool that the back end before using all takes module type interface is very advantageous. Because can change well and truly quickly,clamp is on the machine tool the lesser cutting module of boring lever front, because this is,undertake in holding clip all sorts of cutting provided quite big flexibility. The cutting knife head that CoroTurn SL will carry groove interface and union of photograph of lever of vibration isolation boring are used at boring deepness to be the large hole of 10 times diameter, also had the capacity of HPC. The HPC that cuts with Yu Xi passes a center to cool, HPC also brings profit for milling. CoroMill 690 is special the has HPC capacity long knife that machines at titanium alloy establishs milling cutter. Its every cutting blade is comprised by a lot of razor blade, and every razor blade has corresponding cooling fluid nozzle to offer high-pressured jet for its. Below the circumstance of the whole axial deepness that need not use milling cutter, can use plug to replace spray head, can avoid needless empty eject so and pressure of wasteful cooling fluid. The nozzle that is located in cutting tool to carry a department conduces to a bits, avoid those who cut bits to appear again cutting effect (be in especially model in antrum treatment) . Use the true numerical value of cooling current and pressure to ensure, the optimal application that can use special calculator to realize HPC to go up in milling cutter (parameter of velocity of flow and pressure, cutting, axial cuts the cooling fluid that inputs a machine tool to wait greatly) . This calculator the dimension cipher out nozzle, can realize first-rate to machine the effect so and reduce discharge to ask, high pressure maintains to flow when maintaining place to choose aperture to be passed in cooling fluid at the same time. Titanium alloy chemistry is active, consequently easy in machining a process felt is on cutting blade. This kind of phenomenon can cause those who cut bits normally again cutting effect and crowded bits, affect the life of cutting tool thereby. Machining titanium alloy and other when agglutinant material, HPC is to prevent workpiece material to stick accept a kind of on cutting blade commonly used method. The temperature that arises in machining a process and Shilihui affect integrality of spare parts surface. The use of cooling fluid has certain effect in control temperature respect, because this HPC can offer more reliable surface integrality. Cutting tool nozzle connects with finish machining surface on direct alignment razor blade touched share. Because CoroTurn HP nozzle is not adjustable, can eliminate many variable so, obtain thereby more reliable machine a process with what agree. Optimize union of photograph of full Capto of existing working procedure and coke, join CoroTurn HP very easily these to use an occasion. Compare with photograph of rough machining working procedure, in half fine vehicle and fine vehicle, the hydraulic pressure wedge that cutting fluid comprises uses treatment area more easily, the ply that cut bits is better control, apply hydraulic pressure wedge more easily. High-pressured treatment should be not regarded as to because other uses an ingredient,be made up for (for example bit instability of improper, treatment, cutting parameter is incorrect wait) and the method of the defect that cause. HPC is when working procedure set is basic and correct " optimize implement " . The consistency of spare parts quality that this concept is the handling time with shorter implementation, improvement in turning and milling and higher treatment security provide understanding definitely method. To the demand that all sorts of treatment working procedure optimize, should be formed to cutting bits especially and when the position of treatment station dominant of difficult treatment material, the HPC that uses very easily on current machine tool makes the choice that has appeal extremely. Of the vertical lathe of much task machine tool and new generation increasingly popular already dash forward show the profit that uses high-pressured refrigeration to machine, will look from angle of the pilot that cut bits is such more. As a result of manufacturer more and more the aviation part that uses these machine tools to machine difficult treatment material to be made widely, the troublesome all the more that because how is this eliminated,brings about as a result of the accumulation that cuts bits is important.
