The Mazak Hyper Quadrex 250MSY is a twin-spindle, twin-turret CNC turning center with Y-axis milling, with a reputation for dependable, done-in-one production that has made it a staple in high-volume turning shops. This 2015 machine is configured with a 34-inch bed and is rated for a 14.6-inch maximum swing, 13.5-inch maximum machining diameter, and 33.9-inch maximum machining length, with X 8.2 / Y 4.0 / Z 29.87 inch travels. The main spindle runs to 4,000 RPM with a 35 HP motor, 10-inch chuck, 3.58-inch spindle bore, and 3.2-inch bar capacity, while the second spindle runs to 5,000 RPM with a 30 HP motor, 8-inch chuck, and 2.55-inch capacity through the chuck. Both spindles offer 0.0001-degree C-axis indexing and main-to-sub synchronization for full part transfer. Upper and lower 12-station VDI drum turrets carry 6,000 RPM rotary tools rated at 25.8 ft-lbs, and hobbing software expands the milling capability. The Mazatrol Matrix 2 CNC adds conversational and EIA/ISO programming, a 19-inch color LCD, synchronous tapping, cylindrical and polar coordinate interpolation, LAN and USB connectivity, and 8 MB program memory. Equipment includes an LNS Quick Load Servo 80 S2 bar feeder, Mazak Superflow D8 1,000 PSI high-pressure coolant with coolant temperature control, an automatic workpiece unloader and conveyor, side-discharge chip conveyor, roller guides, and a Sandvik Coromant Capto C4 tooling package with quick-change VDI holders.
The Hyper Quadrex 250MSY was Mazak's step forward from its earlier Multiplex twin-spindle, twin-turret turning centers such as the Multiplex W-200Y and Multiplex 6200Y. The Hyper Quadrex brought the Mazatrol Matrix 2 CNC, Y-axis machining, a large 3.58-inch main spindle bore with a 10-inch chuck, and a powerful 35 HP main spindle paired with a 30 HP integral second spindle. Mazak also designed it around balanced machining, letting both turrets cut the same part at once to remove up to 25 percent of cycle time where part geometry allows. For a buyer, that means more parts per shift, fewer secondary operations, and a more capable machine, not just a newer one.
