Fast processing, brief flow, lowermost charge, these are the advantages that whole machines, machining center can realize the door of PT-MGL series dragon of MFS company such effect. This equipment agrees with milling, grinding and laser quench, intricate work can get on a working procedure whole is machined. Machining center can realize the door of of 4~6 axis PT-MGL series dragon that MFS Maschinenfabrik company makes clamp is right bigger undertake with intricate work milling, grinding and laser quench the whole that waits for a respect is machined. According to manufacturer introduction, this equipment deserves to have the oscillatory damp system with good performance (graph 1) . Graph the 1 dragon that of X the greatest distance is 20 000mm machining center uses the door Yu Xi, grind and laser quenchs treatment is in the advantage that clamp machines to workpiece whole is come from milling the cycle time of grinding is short, need not change cutting tool, save clamping apparatus, as a result of workpiece need not transhipment of through cargo and make treatment precision taller. Use the oscillatory damp system that already acquired patent through be united in wedlock, return the good point that can gain other side, be like older cutting rate, taller treatment precision, better exterior quality, longer cutting tool serves life and short handling time. Dragon door machining center agrees with treatment is ground for example provide and the workpiece such as slideway. Use in union inside when the B axis revolving stage of buy or upside revolving stage, the circle outside can reaching what be less than or be more than 4000mm to bore undertakes grinding. Because this equipment can be used at circular grinding and coordinate grinding. Dragon door, workbench and beam all can walk machining center can carry the dragon door that can walk already, also can equip can walk rotate workbench. If workpiece size is larger, equipment also can install the beam that can walk on vertical axis (W axis) . PG-MGL equipment sets the dragon door that can walk (graph 1) , can use at undertaking machining to placing weight according to the requirement of the user, the journey that goes up in X, Y and Z direction at this moment can amount to 20 000mm, 6000mm and 2000mm. PT-MGL equipment sets what can walk to rotate workbench, the greatest on X direction distance is 6000mm, y way is the oldest the journey is 6000mm, in Z direction the greatest distance is 2000mm. What PT-MGL 5 equipment sets a diameter to amount to 4000mm is feasible go rotate workbench (graph 2) . Equipment of PTQ-MGL 6 equipment has what can walk to rotate workbench and the beam that can walk (the journey of W axis is 2000mm) . Graph 2 contain rotate workbench, x journey grinds laser to quench machining center milling head is mixed for the Long Menxi of 6000mm wheelhead but 90 ° milling head and wheelhead are in circumgyrate ± on A axis but circumgyrate ± 90 can be in random is located locally. Can be when need on circumgyrate milling head or wheelhead add flame of outfit laser temper by dipping in water, can be opposite before grinding from this arris form or slideway undertakes quenching handling. Milling head has following features on power: Power of the biggest drive is 74kW, the biggest torque is 450Nm, the biggest rotate speed is 8000r/min. Circumgyrate A axis can locate arbitrarily and can walk continuously. Of wheelhead most high-power is 52kW, the biggest torque is 500Nm, the biggest rotate speed is 3000 R/min. Circumgyrate A axis can locate arbitrarily. Those who stimulate bareheaded is the biggest quench deepness can achieve 1mm. Long Menxi grinds what laser quenchs machining center can carry mill to get cutting tool and emery wheel to change device, through changing emery wheel, can use the emery wheel with different species or different qualitative capable person namely. Mill grinds laser to quench machining center already applicably at sheet treatment, also apply to batch treatment. Equipment can be used at technology of aviation and spaceflight, drive, turbine, machinery to make, the tool is made, the mould is made, the model is made wait for a domain. CNC Milling
