Made in Kentucky, the Mazak QUICK TURN ZENITH (QTZ) 250 turning center with Multi-Tasking capabilities has several innovative features and functions that bring maximum efficiency and value to small parts production.
Perfect for the automotive, consumer electronics, contract manufacturing and medical industries, the QTZ 250 employs two 20-hp, 4,500-rpm turning spindles for DONE IN ONE parts production, a milling turret with a rotary tool spindle for Multi-Tasking operations and a digital Y-axis for off-centerline machining.
The machine’s integral spindle/motor headstock provides extreme rigidity in heavy-duty machining and unmatched precision in high-speed applications. A variable-speed AC inverter powers the headstock so there is zero blacklash.
The special servo-driven turret on the QTZ 250 offers multiple tool configurations for easy changeover. It also features a roller gear cam drive system, ensuring a smooth high-speed, high-accuracy indexing motion. The roller gear design eliminates the need for expensive components, such as curvic/index couplings.
Together, the digital Y-axis and innovative turret design give the QTZ 250 incredible capabilities. As opposed to being perpendicular to the turning spindle, the turret is parallel to it. Roller gear cam technology drives the turret for infinite radial positioning. This special configuration allows the turret to position in the Z and A (turret rotation) axis to perform Y-axis machining. The configuration eliminates the need for an actual Y-axis slide mechanism, which makes the machine cost effective without any performance sacrifices.
