The T8 Hybrid nine-axis twin spindle mill/turn center from Quicktech combines a three-axis power turret and a 360-degree B axis with a subspindle that features a four-axis gang slide to enable complete machining of complex parts with a capacity of 38 tools. Quicktech machines are distributed in North America exclusively by Absolute Machine Tools.

The machine has two turning spindles and two live milling spindles. The 15-hp main spindle is available with either an 8", three-jaw chuck providing 65 mm (2.6") bar capacity, or a 60-mm collet chuck that accommodates 60-mm (2.4") bar stock. The 42-mm (1.68") collet chuck of the subspindle accepts 32-mm (1.28") bars. Both main spindles and subspindles feature full continuous C axes and are synchronized for fast, accurate part transfer. The Flexible Duo System allows two programs to be run simultaneously, reducing cycle time. Maximum turning length for the main spindle is 345 mm (13.8"); maximum turning length for the subspindle is 330 mm (13.2").

The main spindle has a rigid 12-station, three-axis BMT-55 live turret with a 5-hp spindle motor and 80 mm of true linear Y-axis travel. The turret features fast servomotor indexing and rigid hydraulic clamping, and all 12 turret stations can be live. The subspindle’s four-axis gang tooling system operates in linear X, Y, and Z axes plus a rotary 360-degree B axis. The sub tool post features five OD turning tools, nine OD turning tools and 12 live tools, powered by a 2-hp spindle motor. Rigid tapping is possible in both the turret and B axis.

The machine frame and all major components are made of heavy Meehanite cast iron. Large 35-mm Hiwin roller-type linear guideways in all linear axes provide stability and permit heavier machining. Substantial 32-mm ballscrews are double-anchored, pre-tensioned and directly coupled to the machine’s servomotors.

A matched Mitsubishi CNC system consists of a Mitsubishi M830S control with a 15" LCD screen and Mitsubishi servomotors and amplifiers.
