Overview
The Nakamura-Tome WT-100 is a compact twin-turret, twin-spindle CNC turning center for high-speed small-diameter production up to 42 mm turning diameter and 190 mm length. 42 mm bar, 2,630 x 1,923 mm footprint. Both spindles at 6,000 RPM with 11/7.5 kW, 22 kW combined. Two turrets with mid-position indexing, up to 48 tools, milling motors 7.1/2.2 kW each. Distance 210-735 mm.
New machines $250,000-$380,000. Fixed-headstock approach avoids guide bushing remnant loss.
