QuickTECH T8 Mill/Turn Series – T8 Compact (2-Axis), T8 Mill (3-Axis), T8 Twin Y (6-Axis) with Turret, and HYBRID (9-Axis) Twin Spindle with Turret & B-Axis

The QuickTECH T8 HYBRID mill/turn center combines powerful main spindle turning utilizing a 3-axis BMT-55 power turret with a sub-spindle featuring a 4-axis gang slide, including a 360° B-axis. This high production CNC turning center is cast from Meehanite iron. With a 65mm bar capacity, this unique bar processing center provides complete part machining including all complex milling functions. The T8 HYBRID features 9 total axes, 2 turning spindles, 2 live milling spindles, a B-axis, and a minimum capacity of 38 tools.

Turning Spindles

The main spindle sports a 20 HP high torque spindle motor. The sub-spindle is equipped with a 7.5 HP high torque integral spindle motor for backworking. The main spindle has an 8” chuck with 65mm bar capacity (60mm with collet chuck) and the sub-spindle has 32mm bar capacity. Both spindles feature a full continuous C-axis with braking system. The main spindle is standard with either the 8” 3-jaw chuck or 60mm DIN-185E-60B collet chuck. The sub-spindle is standard with the 42mm DIN-173E-42B collet chuck. The main and sub-spindle are synchronized for fast and accurate part transfer. Both spindles employ P4 high precision bearings for stability and heavy cutting ability.

Tooling System

The main spindle features a rigid 12 station BMT-55 live turret with 5 HP spindle motor and 80mm of true linear Y-axis travel. The turret features fast servo motor index and rigid hydraulic clamping. All 12 stations can be live. The sub-spindle features a unique 4-axis gang tooling system consisting of linear X,Y, and Z axes plus a rotary 360° B-axis. The sub tool post features 5 O.D. turning tools, 9 I.D. turning tools, and 12 live tools. The live tools are mounted in a continuous 360° B-axis. The live tools are powered by a 2 HP spindle motor. Rigid tapping is standard in both the turret and the B-axis.
