Innovation product of Shanteweikekeleman improved the manufacturing efficiency of aviation client. Because carbon fiber increases plastic (CFRP) last in aviation industry with the material folding a layer of metallic alloy with Fu producing main effect, machine demand to also increase increasingly to its so. Among them for example aperture machines working procedure, because its are special some is statified the production blemish with fiber disintegrate, the manufacturing engineers that become manufacturer of whole world aircraft undertake composite material gets the problem that the times feeling when cutting headaches. Now, shanteweikekeleman introduces the expert of cutting cutting tool and cutting tool system CoroDrill 854 and the broach of integral hard alloy of 856 diamond coating, in coming true to machine a process in composite material reliable, efficient machine with high quality aperture. In composite material, beard of fiber, brilliant, grain or fabric material dispersion are in matrix, enhanced tigidity and strength. Some composite material are comprised by with filling structure or the nappe that include titanium alloy and aluminium alloy. These innovation composite material have the part that makes be made lighter, solidder, anti-corrosive wait for a characteristic, suit a variety of aviation application situations very much. Shanteweikekeleman's CoroDrill@854 is compared with 856 broach and aluminium alloy photograph, see the times account that gets favour is in composite material to be able to be as high as 14 times above normally at the tensile strength of CFRP not hard, and the 1/19 that its heat up coefficient of expansion to still be less than aluminous material; In addition its stiffness but tower above 5 times above, and the half that weight is aluminium alloy only. Airbus A380 plane used the advanced composite material of 25% , and the alar plane of 787 dreams uses new Boeing the proportion of composite material is as high as 50% . It is contemporary military airplane even (for instance American F-22) also use composite material, its structure at least 1/3 uses composite material to make; Predict to be able to rise to 2/3 in the future. Composite material wing includes alar bridge, joist wait for such structural member with envelope, the carbon fiber composite material that differs by all sorts of composition normally is formed. The structure with other slashing requirement for example central ala box, form by a few kinds of composite material, return Fu to fold a layer with aluminium alloy and titanium alloy normally. But, as the success application that regards aerospace as composite material, raised new requirement to corresponding process capability. For example, undertake on CFRP aperture adds man-hour, the ability of the structure that get a tip with unique need assures aperture public errand and quality. If machine carbon fiber to increase plastic (CFRP) with other material for example aluminium alloy forms fold board when, because the fabricating characteristics difference of these two kinds of material is very big, the need when the choice machines cutting tool considers corresponding factor. On the foundation that assures bore diameter public errand, coroDrill 854 can be the carbon fiber with newest treatment to enhance composite material and aluminium alloy to fold a material with 856 broach, provide stable, honest cutting tool life. The groovy form design of CoroDrill 854 broach is to raise material of tall fiber content to enter / the quality that gives opening, it is an efficient cutting cutting tool. For example, does broach of use CoroDrill 854 fold a treatment on composite material in CFRP/ aluminium? (6.

The aperture of 35mm) uses parameter of the following cutting normally: Cutting speed is 45m/min; Get deeply 70mm; Feed rate is 0.

03mm/rev; Feed 51mm/min. To achieve optimal treatment result, shanteweikekeleman suggests to use dry cutting or MQL (minim is lubricant) ) cutting condition. To ensure security of process of optimal bore quality, treatment is mixed the production cost of weak opening, choose broach correctly successful to composite material bore is crucial. Considering this, fall to incidental fiber disintegrate or cottony circumstance, had better choose belt " Spurred " the CoroDrill 854 broach of groovy form; If discovery is tall the data that cultivates fat content is very hard control is statified the word of blemish, suggest to use CoroDrill 856 bit -- this basically is because of its design of double vertex angle can make workpiece material can be entered smoothly and exit. Get when cutting composite material, auger cutting axial force is generation statified and break off the main reason that cracks blemish. Accordingly, coroDrill 854 and the distinctive chamfer form of 856 can be reduced auger cut axial force, realize the correct cutting of carbon fiber, in order to satisfy strict aperture quality requirement. In aviation domain, include normally to the requirement of the aperture quality of treatment: The surface is bright and clean spend Ra<4.

8 μ M, what bore diameter periphery is less than 1mm is statified, without fiber disintegrate phenomenon. Kong Shi is machined on material of tall colophony content, the small vertex angle of CoroDrill 856 broach and big before horn conduces to improve opening quality and reduce axial force, to Bao Bi for, this especially important. Product of broach of these two CoroDrill all conduces to eliminate bore burr, improve the appearance bright and clean degree. The cutting trial with extensive Nextpage shows new-style CoroDrill product is increasing production efficiency and lengthen advantage of respect of cutting tool life to highlight. For example, does use CoroDrill 854 fold a layer with aluminium alloy in Fu of CFRP epoxy resin (12mm+12mm) on treatment diameter? (12.

The aperture of 7mm) , treatment makes a person very satisfactory as a result. 118m/min is in cutting speed, feed rate is 0.

Below the cutting parameter of 05mm/rev, the data folding a layer that CoroDrill 854 can process ply to be 24mm 650 aperture -- be equivalent to getting cut 15.

6m! Place poriferous surface is bright and clean degree be in Ra<1.

6 μ M (aluminium alloy) with Ra<3.

2 μ M (CFRP) in, satisfy requirement of level of grade of IT8 public errand at the same time. Those who enter CFRP is statified be very little, and the burr height from aluminium alloy is exited also as it happens is in 0.

Inside the biggest limit of 2mm. In another experiment, no matter CoroDrill 856 is in efficiency or aperture quality respect the broach of excel competitor. Increase in CFRP (acyl of double Ma Lai inferior amine) get on material of high temperature colophony cut? "(6.

When 35mm) aperture, the target is the rate making hole that wants the 300mm/min that defeats competitor set, the Kong Gong that maintains H11 at the same time is poor. Through cutting rate rises 150m/min from 100m/min and appreciably leads feed from 0.

06mm/rev rein in arrives 0.

05mm/rev, coroDrill 856 achieved the rate making hole of 373mm/min not only, and enter hole / the orifice quality that gives end rose 25% . Can offer a diameter for the client at present 4 ～ 12.

7mm (be as long as 5 times diameter) choice, coroDrill 854 is standard coating N20C with 856 broach, coating of this kind of diamond prolonged cutting tool life, suit cutting especially for example composite material a kind abrade material, coefficient of friction is very low. Can mix according to form of specific diameter, length, chamfer material is qualitative (include diamond of hard alloy He Jujing) provide custom-built service, also offer stock product at the same time. Let efficiency fly the treatment efficiency that should improve plane structural member, with respect to the cutting tool that must use correct process designing skill and optimization, such ability satisfy the firm demand that has challenge sex. 8 cutting tool all are the optimal choice that machines plane structural member under. CoroMill 345 economy and high-powered leading edge seam alar slideway is a part that forward position technology has extremely on dynamical structure, its material is tall alloy steel and stainless steel normally. CoroMill 345 holds the razor blade that contains 8 cutting blade, and every chamfer that discharge bits can be offerred inside cold, ensure the scrap when processing difficult treatment data can gain very good control, achieve optimum behavior thereby. The machines means terminator that purify of CoroMill Plura low metal leads is perpendicular empennage is composite material, its repair Bian Xi to have very big challenge. CoroMill Plura diamond (grain and solder) establish milling cutter and cutting tool of diamond coating hard alloy, suit great majority this kind of application, not only can reduce fiber burst, still can raise metallic purify rate. CoroTurn SL and decrease brace up cutting tool Silent Tools is efficient and the treatment of the spare parts needs vibration isolation landing gear efficient with quick solution. Lever of Silent Tools boring is designed for vibration isolation only, cooperate head of CoroTurn SL cutting, range of Silent Tools application is very wide, include refrigeration of use high pressure inside aperture treatment. Its advantage can pass treatment function and stability to measure. The CoroDrill 854, 855 main challenges that undertake with 856 pairs of composite material composite material machines box of carefully of bright and clean drill are phyletic and various bore. CoroDrill 854, 855 and 856 design to reach optimal aperture mass technically, of these broach getting a tip can be diamond (grain, riveting, solder) or the hard alloy of diamond coating. The rack of treatment means engine with lighter CoroMill 210 has one feature to be machined very hard, its centrally has a deep long and narrow chamfer. Milling cutter of tall feed CoroMill 210 can realize light treatment, and metallic purify rate is extremely high. This kind muti_function cutting tool can be used at face mill, successive slope to go mill and insert mill to wait. The structural member of treatment hotshot airframe of alloy of CoroMill 690 titanium has a lot of is titanium alloy spare parts, landing gear crossbeam is an example. CoroMill 690 is special the corn milling cutter that machines at titanium alloy, its unique bit location design and whorl nozzle ensured rate of tall metal purify and high security. The cutting tool with S30T and the most advanced S40T is main the frame of material wing tailing edge, its material is titanium alloy normally. When titanium alloy milling, the negative charge of heat in metal cutting that generates on milling point, chemical bear, mechanical bear approachs the limit of material of all and foregone cutting, and material is S30T and S40T technically to solve these most advanced problems and be developed character. CoroMill 790 is aluminium alloy normally with the alar costal region of wing of contracted get victory, its treatment has challenge sex very much, but the CoroMill 790 chamfer of new design can solve this problem. The location design of bit is unique and security is high, the likelihood that the radial load place that because high speed machines generation,can eliminate brings is sequential.
