9-Axis Twin Spindle Multi-Tasking Center with B-Axis
July 1, 2013
Absolute Machine Tools has introduced the Quicktech TTS-42/TTS-60 9-axis twin spindle multi-tasking turning center. The CNC bar processing center enables complete part machining including milling of complex features.
Available in both 42 mm and 60 mm (1.65" or 2.36") bar capacities as the TTS-42 or TTS-60, the machines feature nine axes, two turning spindles, two milling spindles and a capacity of 31 tools. A 3-axis (XYZ) gang type vertical tool post serves each spindle with the main tool post featuring a full B-axis for the live tools. Maximum turning length for the main spindle is 226 mm (9.05") and maximum turning diameter for the subspindle is 98.5 mm (3.94").
The main spindle has a 15 HP high torque spindle motor and the sub-spindle is equipped with a 5 HP high torque spindle motor for backworking. Both spindles feature a full continuous C-axis with braking system and standard 42 mm DIN-173-42B collet chucks. The main spindle has either 42 mm or 60 mm draw tube bar capacity, the sub-spindle has 30 mm (1.18") draw tube bar capacity and the spindles are synchronized for fast and accurate part transfer, according to the company. The cartridge-type spindles employ P4 high precision bearings for stability and heavy cutting ability.
Each spindle is served by a 3-axis gang tooling system. The main spindle tool post features six OD turning tools, four ID turning tools, three radial live tool heads and three axial live tool heads. The sub-spindle tool post features four OD turning tools, five ID turning tools, three axial live tool heads and three radial live tool heads. The live heads are powered by a 2 HP spindle motor. The B-axis allows the live tools to rotate -45° to +130° and be applied to both the main and the sub spindle. In addition, each tool post has a Y-axis for off-center milling operations.
Gang tooling produces tool change times near zero. Kennametal KM-25 quick-change tooling is standard and KM-25 bases are supplied with the machine for OD turning tools. Rigid tapping is standard. The machines employ large 35 mm (1.4") Hiwin linear guideways in all linear axes for stability and to allow heavy cutting. The ballscrews are double anchored, pre-tensioned and direct-coupled to the Mitsubishi servo motors to maximize precision. The machine frame and major components are made from high quality cast iron and the machine weighs 9,240 lbs.
