Absolute Machine Tools’ Quicktech’s T8 Hybrid nine-axis twin spindle mill/turn center has two turning spindles and two live milling spindles and combines a three-axis power turret and a 360° B-axis with a sub-spindle that features a four-axis gang slide to enable complete machining of complex parts with a capacity of 38 tools.

Absolute Machine Tools, Inc.’s Quicktech T8 Hybrid nine-axis twin spindle mill/turn center combines a three-axis power turret and a 360° B-axis with a sub-spindle that features a four-axis gang slide to enable complete machining of complex parts with a capacity of 38 tools. The T8 Hybrid has two turning spindles and two live milling spindles, the company says. 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 sub-spindle accepts 32 mm (1.28”) bars.

Both main and sub-spindles feature full continuous C-axes and are synchronized for part transfer. The machine’s Flexible Duo System allows two programs to be run simultaneously, reducing cycle time by up 45 percent. Maximum turning length for the main spindle is 345 mm (13.8”) and maximum turning length for the sub-spindle 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 sub-spindle’s four-axis gang tooling system operates in 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, powered by a 2-hp spindle motor and mounted in a continuous 360° B-axis. According to the company, rigid tapping is standard in both the turret and B-axis.

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 35 mm Hiwin roller-type linear guideways in all linear axes provide stability and permit heavier machining. According to the company, substantial 32 mm ballscrews are double anchored, pre-tensioned and direct coupled to the machine’s servo motors.
