Place of company of SHW Casting Technologies of no less than says, when high accuracy machines carapace of large scale computer, boring machine can show its advantage. Before before long, this company is on milling machine of boring of type of a Pama Speedram 3000 be born, to 80? The equipment base with heavy T undertook machining. The history of company of SHW Casting Technologies is be located in Shiwaben with its of smeltery cast an activity to begin (graph 1) . Because SHW company is located in the factory of Heidenheim to want every year to cast and machine 50 ～ ,wind-force of 60 coastal waters generates electricity the base of equipment, offer the product to the user, this company decision does not give this business subcontract outside assist factory, however by oneself K? Nigsbronn factory will do. The factory controller Stephan M of company of graph 1 SHW Casting Technologies.

Mr Stuby (left) with Kai F of Pama company selling manager? Ground of Mr Rster all with one voice praises the Stephan M of controller of good cooperation factory on project of boring milling machine.

Stuby and Uwe Kn of job shops director? New to its machine is having Bel clear idea: "The equipment base that expects by high quality casting bucking the 80t that makes is heavy should use two process (graph 2) , undertake with identical dependability, identical efficiency and same precision whole is machined. " among them, the diameter of the bearing aperture on equipment base achieves 3200mm, its machine tolerancepublic errand to be H7. Course and 3 inquiry peace conference that the manufacturer has talk. "We more milling machine of boring of apt choice Pama Speedram 3000 be born. But the price is not the mainest factor that we consider. " factory leader Stuby emphasizes saying, "See the good cooperation rate of the precision of equipment and phase of project early days even however. " . The wind-force with graph heavy 2 80t generates electricity the preform of equipment base after completing treatment, weight reduced 10t this machine tool to deploy those who have a 100kW about advocate drive, in S1 moving condition falls, its achieve 13470N · M in the moment of force on main shaft. Still match those who a diameter is 180mm to bore hole additionally the workbench that axis and a dimension are 5000mm × 5000mm. The transverse journey of the machine tool achieves 2500mm. Machine to can undertake to the inside face of equipment base (treatment hind is used at pitching moment to prop up) , SHW company still is the milling head of an orthogonality, add ordered particularly long special model horny broach. Boring milling machine is mixed in X, Y Z up the journey is 18000mm, 6500mm and 1400mm respectively. Boring axis (W axis) axial journey is 1200mm, (of W axis and Z axis) Cheng of axial head office is 2600mm. Compensation system can ensure continuously treatment precision. The situation that with main shaft the centre of gravity of box produces deflection or frame happening tilts is same, when static fluid props up sleeve happening enclosedly to bend, also can get compensating. In boring milling machine move coming back moves the flat by the stage to go up, the equipment base that machines through the first working procedure is retroflexioned and by Jiao Zhi, be placed to hold next, so that begin precision work. "After machining the first working procedure, retroflexion the task that equipment base is a difficulty. Pass according to 1:2The tool model that 0 scale make, we obtained accurate load to distributing data. " Kn? Bel explanation says. Make a firm one case with a cutting tool, formulate treatment plans orderly. During this, boring milling machine works 3 classes for successive 24h all the time. The treatment of base of the equipment that finish, need about 150h. After treatment, this giant the weight of workpiece reduced 10t about, but still 70t is weighed. CNC Milling
