Mazak North America’s QT-Ez 12MY is a horizontal turning machine with an 12" chuck, milling and Y-axis, off-centerline capabilities for multi-tasking functionality.

The QT-Ez 12MY uses a larger A2-8 spindle nose with 3,300 rpm, 22 kW (30 hp) and 285 ft-lbs of torque, as well as a 3.0" (76 mm) bar capacity. Within its 12-tool turret, the machine’s standard 6,000 rpm milling spindle provides 10 hp (8 kW).

On the QT-Ez 12MY, Mazak offers an optional 10" chuck for greater maximum rpm capability. Available machine turrets include drum style with bolt-on tools or a BMT55 turret for rotary tool applications. The no-tailstock option supports chucker-style operations while the standard manual-body tailstock includes a hydraulic quill and #5 live center that provides 1,124 ft-lbs (5,000 Nm) of thrust. The optional servo-driven tailstock with #5 live center provides up to 1,574 ft-lbs (7,000 Nm) of thrust.

To further aid shops in maximizing productivity, QT-Ez Series machines are designed for easy installation of a range of automation solutions, from simple bar feeders and parts catchers to full collaborative robot installations such as Mazak Automation Systems’ CC-10 and CC-16 Cobot System models.

The CC-10 system uses a FANUC CRX-10iA/L with 10 kg payload capacity, while the CC-16 is built around a Universal Robots UR16e platform with a 35.27 lb (16 kg) payload capacity. Both cobot models come with three available grip systems and use an area scanner with limited fixed fencing for fully collaborative human-robot workflows.

Like all QT-Ez Series machines, the QT-Ez 12MY features an integral motor headstock, hybrid MX roller guideways and pre-tensioned ball screws supported at both ends for reliable, thermally stable and precise machine-axis movement. A new bed-casting design is said to provide outstanding rigidity, as well as streamlined chip flow to help eliminate chip accumulation. For ease of integration, the machine incorporates a 200-230 Volt power supply system.

Along with optional spindles, chuck sizes and tailstocks, the QT-Ez Series is available with a complete range of additional options, including Mazak’s Automatic Tool Eye, chip conveyor, auto door, auto parts catcher and high-pressure coolant systems.
