The T8 Hybrid 9-axis twin-spindle mill/turn center from Quicktech combines a 3-axis power turret and a 360˚ B-axis with a sub-spindle that features a 4-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 Inc.

The T8 Hybrid has two turning spindles and two live milling spindles. The 15-hp main spindle is available with either an 8", 3-jaw chuck providing 65mm (2.6") bar capacity, or a 60mm collet chuck that accommodates 60mm (2.4") bar stock. The 42mm (1.68") collet chuck of the subspindle accepts 32mm (1.28") bars. Both main and subspindles feature full continuous C-axes and are synchronized for fast, accurate part transfer. The machine's Flexible Duo System allows two programs to be run simultaneously, reducing cycle time by up 45 percent, according to the company. Maximum turning length for the main spindle is 345mm (13.8") and maximum turning length for the subspindle is 330mm (13.2").

The main spindle has a rigid 12-station, 3-axis BMT-55 live turret with a 5-hp spindle motor and 80mm 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 4-axis gang tooling system operates in linear X-,Y-, and Z-axes plus a rotary 360˚ B-axis. The sub tool post features five OD turning tools, nine ID turning tools and 12 live tools, powered by a 2-hp spindle motor and mounted in a continuous 360˚ B-axis. Rigid tapping is standard in both the turret and B-axis.

The T8 Hybrid is reportedly engineered for precision and durability. The machine frame and all major components are heavy Meehanite cast iron. The turret Y-axis is a true linear axis, perpendicular to the X-axis for maximum precision. Large 35mm Hiwin roller-type linear guideways in all linear axes provide stability and permit heavier machining. Substantial 32mm ballscrews are double anchored, pretensioned and direct coupled to the machine's servo motors.

A matched Mitsubishi CNC system consists of a Mitsubishi M830S control with a 275mm (15") LCD and Mitsubishi servo motors and amplifiers for top reliability and performance. A FANUC OiT-F control with a 275mm (15") LCD and matched FANUC motors and drives is also available. Standard machine features include a bar feeder interface, parts conveyor and catcher, chip conveyor, collet chucks and a 400-psi coolant pump.

Steve Ortner, president and owner of Absolute Machine Tools, said, "The T8 Hybrid machines represent a blend of machining technologies that enables users to enable users to maximize both productivity and efficiency."
