Spaceflight is mechanical the good news of material of component · difficult treatment

To save fuel resource, those who begin to take airframe seriously more and more is light quantify. Wing, the frame of airframe uses aluminium alloy still a lot of, the client demand to treatment (platoon bits, efficiency, machine a method) taller and taller. Hardness of heat-resisting alloy high temperature is tall, and high temperature environment falls fight oxidisability, corrosion resistance is good, be applied extensively at engine of jet-propelled of instrument of boat nature's mystery and vapour turbine and chemical equipment consequently, the high temperature such as rubbish combustion furnace issues use appliance. Be in especially be able to bear or endure with nickel ferrochrome heat-resisting the nickel that corrode alloy is a delegate base the wide application of domain of heat-resisting alloy engine. Additional, the corrosion resistance of titanium alloy is very good, compare the hardness that has 60% only with steel photograph, its regard a kind of intensity as very expensive stuff by everybody place is hep, be expected as airframe material by spaceflight unit place is used extensively. These material heat up conductivity not only very low, saving of meeting general quantity of heat is in blade point, make of edge wear away very quickly, and material itself is very costly, it is very difficult to because this is machined,rise. Introduce this company ceremoniously here new roll out apply to heat-resisting alloy milling cutter of the special DV-OCSAR 10 thousand horn that chop a circle and machine clip type are efficient treatment is used be proud leopard series. 10 thousand chop series of gentle circle horn this tool uses round horn to carry milling cutter for heat-resisting alloy. 1.

Of part of round part of diagnostic ① edge before knife face uses helix blade form, reduce cutting resistance greatly thereby, and the helix angle of each point and before horn each are not identical, what because this was eliminated,cut obstruction change is periodic, can restrain vibration (already patent application) . Picture (1) ② is used before horn, point is sharp degree admirable, reduce conglutinate. ③ uses big helix angle of ° of 42 ° ~45, cutting resistance is little. ④ uses the JC8010 overflow coating of new development, the coating with the base material with implementation hot tall conductivity and heat-resisting superior performance is perfect be united in wedlock. Corner of graph 1 Ti6Al4V is machined 2.

The treatment example of titanium alloy uses R2) of × of DV-OCSAR4100-R20(Φ 10mm, treatment produces oscillatory corner place extremely easily to undertake evaluating a test. From graph 1(right) in knowable before the meeting when the product is machining corner leaves very deep shake Dao Wen, be aimed at the circumstance of incidental when treatment vibration, new product DV-OCSAR can prevent vibration effectively, raise the precision that machines a face. 3.

By treatment content (SUS304) treatment example pursues the 10 thousand horn that chop a circle carry alloy of heat-resisting of appearance of workpiece of 2 thin walls milling cutter this company before the product is other the company because in recent years the Bao Bi of turbine lamina machines content to increase in great quantities, r2) of × of 10mm of use DV-OCSAR4100-R20(Φ , be like to pursue by treatment content 2 are shown, cut deeply 0.

Of 5mm outside tilt treatment, the performance of edge R department that checks milling cutter (graph 3) . With the company before the product photograph of product and other company is compared, through differring the effect of the lead, horn before differring, although Bao Bi's treatment also can be not had,shake achieve good cutting appearance. Graph 3 surfaces are bright and clean degree of NextpageDV-OCSAR400-R20 guide milling cutter differs lead milling cutter [be proud leopard series] this tool is efficient milling cutter of type of clip of · high accuracy machine (knife of 1) feature ① is long make an appointment with 15mm, horn of point of a knife is the razor blade of 65 ° , can undertake late chance to extricateoneself from an awkward position is machined not only, groove treatment, still can undertake declining and helix cuts treatment. R of ② point of a knife has 0.

4~3.

2mm 7 kinds, can answer the treatment of all sorts of clear root horn. Material of ③ razor blade is had character, aluminium alloy treatment uses [FZ05] , titanium alloy stainless steel machines the whole set of used JC5118. ④ cutter hub used endurance of tall rigid · better [G-BODY] . [G-BODY] : Will have extremely special steel undertakes the Jiang Ren of actor hear resistance special GN processing, exterior hardness achieves HRC65 above, and heatproof be out of shape capability is strong, tall tigidity has extremely strong vibration to absorb ability at the same time, because this uses the bit life of G-BODY bit body to raise 30% above at least than traditional cutter hub, and still be had prevent the conglutinate that cut bits and antirust effect. ⑤ cutter hub has, [can exchange type knife head] , arbor, inside bit body cold model whole set. What ⑥ passes high accuracy is three-dimensional the razor blade that decides the form that cut groove and cutter hub will achieve reduce resistance and the result that improve treatment face precision. (2) aluminium alloy machines example to be in aluminium alloy treatment, deep model the case with very large amount of speech material purify is very much, accordingly, raised the efficiency that discharge bits to become the key of treatment. The aluminous ingot capable person that if the graph is shown 4 times,has with MAL-2025-M12(Φ 25mm) is machined. Graph condition of cutting of workpiece of 4 aluminium alloy: Rotate speed: 1256m/min feed: 0.

25mm/Rev cuts deep Ap=5mm to cut) of wide Ae=25mm15mm(flank, above 5mm() cut corner: Eduction of the biggest cutting measures 10 ° : Treatment of 1000cm³/min dry type is a few otherer generation of the meeting when similar product is machined wears away, dan Aobao series not only did not wear away and lateral verticality also is in 0.

02 less than. (Because hot conductivity is very low,3) Bao Bi machines example titanium alloy, the quantity of heat when cutting is accumulated easily in edge, the endophilicity with the tool is very additionally tall, appear very easily in point of a knife conglutinate, cause tiny collapse to be short of. Accordingly, cutting resistance is low, not easy conglutinate, sharp blade contrast very be necessary, and it is good to must choose hear resistance, the cutting tool material that the capable person with nice tenacity plants is qualitative. 63mm) of use ALX5063R(Φ , made process material of titanium alloy ingot the Bao Bi part that has 10mm only into ply. (Graph 5) pursues rotate speed of condition of cutting of workpiece of 5 TiAl4V Bao Bi: 40m/min feed: 0.

5mm/Rev cuts deep Ap=8mm to cut 5mm(of → of 10mm of → of 20mm of wide Ae=40mm → from arrive greatly little change) outside the quantity of eduction of the biggest cutting of cold unit time is 32cm³/min, even if thin wall treatment also can restrain vibration effectively, and machine face precision good. As the development of spaceflight industry, henceforth is aluminium alloy not only, the heat-resisting alloy use amount that cuts timber hard also can rise at full speed. Introducing this company two kinds of new products while, henceforth also the demand prep against client, development is more efficient, more the tool of high accuracy! CNC Milling
