FLORENCE, Ky., August 6, 2019 – To help manufacturers achieve the highest level of overall throughput, Mazak Corporation has designed its Kentucky-built QUICK TURN 200/250 Series of CNC turning centers as a flexible machine base suitable for numerous highly productive configurations. One such example, the QUICK TURN 250MSY Multi-Tasking Turning Center with GR100 Gantry Robot, offers full DONE IN ONE® part-processing capabilities and fully automated part loading/unloading with the GR100 Gantry Robot for exceptional production efficiency.
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 featured on the machines. 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” in diameter, 6” in length and total weight of 44 lbs. The field-proven 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 3,937 ipm rapid rate on the robot’s A axis and 7,087 ipm rapid rate on its B axis.
The QUICK TURN 250MSY headstock features a 10" main chuck mounted on a 35 hp, 4,000 rpm integrated spindle motor that generates 343 ft-lbs 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-degree increments. A second spindle with 15 hp, 6,000 rpm 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 10 hp, 6,000 rpm and 52 ft-lbs of torque. And with an optional tooling package, 10,000 rpm 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.
