Graph the 1 G 550 that contains circular circumgyrate workbench 5 axes machining center. Its achieve 800mm, 950mm and 1020 MmG 550 5 axes respectively in the journey on X, Y and Z axis machining center is OK the contains husk oil cylinder workpiece that amounts to 900 Mm to containing a diameter undertakes efficient with quick treatment. To this, can use be as long as the cutting tool of 500 Mm. Through using the knife warehouse of a kind of double plate, can undertake in exercise while, realize the transhipment of through cargo to a bit body. After accompanying G 350 5 axes two years when machining center enters field of standard machine tool successfully, grob-Werke company expanded again range of product of its standard machine tool, rolled out larger G 550 machining center (graph 1) . This company place says no less than, of new-style machining center it is important to roll out the next that should become a company to promote the market portion in this domain with certain measure. G 550 machining center can offer the treatment opportunity that processes bigger norms work to the user. The journey on X, Y and Z axis can achieve 800mm, 950mm and 1020mm. The height that can process the greatest work (pure B axis) for 735 Mm. For the machine tool production manufacturer to this Mindelheim area, those who have company strategy sense is to should extend the market with existing market share and new development. Want to aim at an international market especially, because greater market potential is had over,this is, g 550 machining center can produce its advantage adequately. Collect of G 550 machining center 350 model all advantages of the machine tool at a suit, the shape of a distribution of its axis is for Y, A and B axis on workpiece, and X and Z axis are on cutting tool, because have horizontal main shaft and circular circumgyrate workbench,wait for an advantage at the same time, accordingly, can have 5 treatment to containing the contains husk oil cylinder workpiece of 900mm diameter (graph 2) . To this, can use be as long as the cutting tool of 500 Mm. Graph while library of knife of 2 double plate allows to undertaking cutting works, change an among them bit body application in cutting tool respect, g 550 machining center can offer a variety of use program. Besides the main shaft that contains port of HSK A-63/SK 40 cutting tool, machining center still can deploy the main shaft that applies to tool carrier of HSK A-100/SK 50 interface. Traditional choose pattern changes knife system to get expanding, augment economic space and time double plate knife library program (graph 3) . Can bring into the cutting tool position of 60 HSK A-100 or 120 HSK A-63 from this. Nextpage pursues the cutting tool that the 3 contains husk oil cylinder workpiece that contain 900 Mm diameter can amount to 500 Mm by length undertakes 5 treatment use double plate cutting tool, can having operation while, undertake changing to a bit body, right now, be aimed at the real time treatment of workpiece, can change cutting tool directly from another bit body by arm of double ungual cutting tool (graph 4) . To HSK 63 cutting tool, have 60 cutting tool store can be aimed at SK cutting tool for using; , have 50 cutting tool store. When using HSK 63 cutting tool, the time changing a knife between working procedure is 4. 3 S. The cutting tool arm that the graph contains double claw one kind 4 carries on company of Grob of the task that change a knife thinks, on equipment of standard type machine tool, main shaft is producing very main effect. In all equipment plan, it also makes rod of electric machinery drive. Besides it is people place namely on G 350 machining center besides hep HSK A 63 main shaft, moment of force is powerful (the HSK A 100 of 575N · M) main shaft suits to be used on G 550 smooth machining center very much. In addition, still one kind contains very tall moment (what M) of 223 N · and the biggest rotate speed are 16000r/ Min is general-purpose axis of electric machinery drive can be offerred use. Still having a new function is diagnostic function. Introduce according to Grob company, the diagnostic respect that processing a rod still develops a kind of attachment, what it can think the user realizes milling flow is visible. Accordingly, have the aid of is quickened at showing what go up in control screen to swing, swing speed and temperature curve, can optimize cutting technological process not only, and the service life that still can improve treatment axis and cutting tool.
