2005 Mori Seiki MT3500S/3500 8-Axis CNC Turning Center

The 2005 Mori Seiki MT3500S/3500 CNC Multi Tasking Turning Center unites a 120-degree B-axis universal milling head with synchronized C-axis control on both spindles to 0.001-degree, a ±4.3-inch Y-axis, and long-bed 125-inch centres to machine large shafts and complex features in one pass. Dual 12-inch hydraulic chucks on A2-8 noses grip through about 4.1-inch bores, the main spindle turns to 3000-RPM with about 40-horsepower while the sub reaches 4000-RPM with about 20-horsepower, and the universal head mills to 8000-RPM with 15-horsepower from a 120-tool magazine; X-25-inch and Z-125-inch travels with rapids around 944-IPM X and 1181-IPM Z move the cut along briskly, aided by two 12-inch programmable turn-through steady rests and a 1000-PSI high-pressure coolant lance that clears deep bores.

Compared with a conventional single-spindle turning centre lacking B-axis and sub spindle, the MT3500S/3500 adds full contouring on the universal head, live milling at 8000-RPM, hand-off to a synchronized sub for second-end work, and a 120-tool magazine—compressing multiple set-ups into one stable, thermally disciplined cycle while preserving the long 125-inch working envelope.
