Quicktech T8HY Mitsubishi pressClick image to enlarge

The T8 Hybrid 9-axis twin spindle mill/turn centre from Quicktech 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.

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 in., three-jaw chuck providing 65 mm (2.6 in.) bar capacity, or a 60 mm collet chuck that accommodates 60 mm (2.4 in.) bar stock. The 42 mm (1.68 in.) collet chuck of the sub-spindle accepts 32 mm (1.28 in.) bars. Both main and sub-spindles 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 per cent. Maximum turning length for the main spindle is 345 mm (13.8 in.) and maximum turning length for the sub-spindle is 330 mm (13.2 in.).

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. 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. Substantial 32 mm ballscrews are double anchored, pre-tensioned and direct coupled to the machine’s servo motors.

A matched Mitsubishi CNC system consists of a Mitsubishi M830S control with a 275 mm (15 in.) LCD and Mitsubishi servo motors and amplifiers for top reliability and performance. A Fanuc OiT-F control with a 275 mm (15 in.) 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.
