Clausing's heavyweight Colchester-Harrison TT6 turn-mill center provides overlapped (twin turning) tool sequences. Even the most complex workpieces can be machined simply, accurately and without setup changes, the company says. Setup times are reduced by about 25 percent and waiting time between processes are eliminated.

The eight-axis machine has twin 12-station turrets, two identical 20-hp integrated spindle units, a Fanuc-GE servomotors and drives, and the Fanuc 31i-A CNC control, which has a high speed, low power CNC processor, simple programming and operator prompts. A 10.4" LCD screen is standard.

To deliver the high strength and rigidity necessary to absorb cutting forces and vibration, the 45-degree slant bed takes advantage of a Y-axis wedge-angle configuration and 35-mm linear guides on all axes. The tool drive has spindle orientation, with the tools individually driven and radial tool mounting. The X and Y axis linear scales are standard. The Z-axis absolute position encoders require no referencing at power-up. Production planning screens allow for batch processing of several different components. Tool setting screen aids, tool life/sister tool monitoring and simple setup for hex bar transfers are also featured.
