Mazak adds automation to Quick Turn 250MSY + GR100
The Kentucky-built Quick Turn 200/250 series of CNC turning centers are flexible machines suitable for highly productive configurations, such as the Quick Turn 250MSY multi-tasking turning center with GR100 gantry robot offering Done In One part-processing capabilities and fully automated part loading/unloading.
Mazak pre-engineered the GR100 to easily integrate into any of the Quick Turn 200/250 series machine models, including the 2-axis, milling, Y-axis, and/or second spindle versions. To interface with these Quick Turn machines, the GR100 requires no special robot/machine interface and programs easily via the Mazatrol SmoothG CNC. For application flexibility, two GR100 workpiece-table configurations are available, as is end-of-arm tooling with three-jaw grippers.
All GR100 robots come equipped with a simple-to-configure, D3, two-sided, three-jaw gripping hand with a part range up to 7" dia., 6" in length and total weight of 44 lb. The D3 hand design allows shops to load/unload a wide variety of chuck work. To significantly reduce machine idle time, Mazak complements the GR100 with the integration of a fast, servo-driven automatic door that allows the robot entry into the machine envelope at a 3,937ipm rapid rate on the robot’s A axis and 7,087ipm rapid rate on its B-axis.
The Quick Turn 250MSY headstock features a 10" main chuck mounted on a 35hp, 4,000rpm integrated spindle motor that generates 343ft-lb of torque for heavy-duty metal removal. To accurately position parts for square facing/slotting cuts and precisely drilled holes, the machine’s main turning spindle also serves as a full-functioning C-axis that is programmable in 0.0001° increments. A second spindle with 15hp, 6,000rpm and a 6" chuck allows the Quick Turn 250MSY to automatically transfer parts and perform secondary operations with speed and accuracy.
The machine’s 12-position, direct-drive turret eliminates the use of belts for improved part surface finishes and reduced maintenance. It can be configured with either VDI or bolt-on tooling. The turret’s rotary tool spindle delivers 10hp, 6,000rpm and 52 ft-lb of torque. And with an optional tooling package, 10,000rpm is available.
The GR100 robot package offers two-workpiece table configurations, including a 2-pallet changer that allows parts to be positioned in rows across each table and a 16-position rotary stocker system with the ability to stack parts on each individual stocker. The 2-pallet changer makes it possible for operators to access the pallet on one table while the other table is shuttled into the load/unload area for uninterrupted machine operation. The rotary table design with stacked parts allows for greater initial density of parts but without access during automatic operation. A single part-discharge tray can also be added for unloading specified parts for inspection.
