The application of DMG vertical lathe in aerospace industry brief introduction

7 already also detected through 100 multinomial flights (more powerful Centurion 4.

0 derv engine also obtained attestation, and the Centurion 3 that is in intermediate limits.

0 fronts face in-house check and ratify) . On the other hand, although hamburger is located in 15 years ago carry forcing a company is the supplier that serves as to be car motion to supply special part only and of build up, and now still is the systematic partner of automobile industry, but its run an activity outspread already arrived a quite big range: Germany lifts the lofty aspiration that forces aviation engine company is the spare parts supplier of the systematic partner that becomes industry of aviation of alliance of traditional the first line of a couplet on a scroll and manufacturer of groovy aviation engine. The use that linear of two connective CTV 250 machines equipment carries Le Hang for Germany empty engine company shortened manufacturing time, improved the service life of cutting tool. Mr Rudolph made such explanation: "To us character this is not contradictory, our derv aviation engine made a product line, the old customer's order is another. Although our Centurion engine holds the sale of more than 80% now, we still are systematic partner and spare parts suppliers. " of course, the investment that promotes opposite of company of engine of the sky that force boat to produce kind decides to be based on its oneself demand, is not apparent according to outside order. Although preliminary decision supports the machine tool of DMG, but investment accepts extensive assessment even. The two treatment unit with lathe of linear vertical of two connective CTV 250 is exemple. It not only can fast forthrightly along X axis steep drive, this is a crucial factor that creates empty knife time; And crucial is its intensity apparent prep above is average stiffness, make cutting time was lengthened thereby 30% . Introduce according to Mr Rudolph, on these two CTV they can machine the cylinder that forgings by the tall alloy of not easy cutting and chromium steel of high strenth nickel, raw component weighs 10kg, finishing cylinder weighs 5kg only, excision rate is very consequently high. The precision of the requirement is likewise such, those who be like line of cylinder aperture center and centering connect is homocentric degree must not exceed 1% . 50~70mm is before final honing when the machining error of cylinder aperture when, its geometry precision must be achieved at least before fine vehicle 5% . Those who change character, really cannot the requirement of look down on to process capability and geometry and positional precision. Accordingly, if did not measure cutting integratedly, accomplish nothing. In addition, 20 groove must be machined all round cylinder, every deep 12.

5mm, wide 3mm, use at placing every wide 0.

The carbon fin of 8mm. Another intractable turning operation is the groove after dig cuts contact, still must use a kind to come from the cutting tool with special Seco to this. Mr Rudolp recollects and summary arrives: "Should not say to be in more hard forging initiative cutting of the surface, so CTV must satisfy a lot of different levels, but in this on one hand we also can complain without what. " and, mr Rudolph can compare the cylinder that has machined on two DMG general lathe up to now, it is NEF of a turret lathe first, it is a CTX subsequently. Although our oversight inevitable relevant carry and latency time, be operated with respect to turning only and character, two equipment spent 45min. And now, two connective CTV needs 20min every only. Doubt of this need not had advantageous proof to their function. But although all conditions got satisfaction, if lathe cannot move below environment of 2 heavy systems, thereby whole turning unit will be in halt condition, still be no good so. Mr Rudolph says: "We return the technical usability to two CTV to feel very glad, the technical usability of whole unit exceeded 90% far. " what must remember well at the same time is, unit should endure a week 5 days, everyday the high load capacity of 24h in rotation. You may assume, the first it is with handling time of lateral of the 2nd cylinder every time 20min, add pair of unfinished to taste, the large storage capacity of semi-manufactured goods and finished product, when the 3rd moves ought to unmanned and attendant. Mr Rudolph says: "Unfortunate is, fractional problem makes its become impossible. Although we were controlled,move for the most part, but still can produce intricate fragment now and then, operate personnel must its eliminate, do not allow unmanned and attendant operation consequently. " now, germany carries company of engine of the sky that force boat to stride a company to order two CTV 250 that join together as an unit especially from German auspicious not only linear treatment facilities, still ordered complete set technology first, namely NC process designing and cutting tool (what conveniently carries is, two tool carrier are completely in Qian beyond the cutting tool with dish of the first stage medium equipment) . Mr Rudolph explanation praises when to auspicious strides the know-how of the company especially, say: "Our flight engine cylinder still is the part that the government approves at the same time, have the CMK attestation of formulary run time and ISO639. It can work at the beginning, so far we need completely synchronous change only the run time of all 5 cylinder variable, as a result of number is relative less, can press these variable to be tasted to same unfinished easily undertake turning. " in this process, in-house diameter differs from 127~134mm, respective machining error as much such. Although in principle is usable also,rotate cutting tool undertakes machining, but go up to undertake turning to cylinder only in two CTV linear machine tool, an operation is only exceptional -- integrated laser scanner reads the component number that takes stickup label to go up, according to reading, milling cutter cuts this number to each components. Mr Rudolph is profuse in praise to this: "Other vendor cannot also won't provide this kind of machine tool, it is auspicious even striding a company especially also is this come true first on the 2 heavy unit in us. " accordingly, this is to support this company to believe firmly using linear of two connective CTV to machine equipment is his another reason of sensible choice. CNC Milling
