Overview
The Nakamura-Tome NEW TW-30 is a heavy-duty two-turret, twin-spindle CNC turning center for larger-diameter parts with 335 mm turning diameter and 71 mm bar through a 10-inch chuck. Prioritizes rigidity and bar capacity over milling sophistication. Both spindles at 3,500 RPM with 22/18.5 kW matched power. Non-lift servo-driven turrets with 24 stations (expandable). Servo motor torque control for precision part transfer. Distance 320-1,300 mm. 10-in chuck (12/15-in optional).
4,975 x 2,606 mm footprint. New machines $300,000-$450,000.

Frequently Asked Questions
01
$300,000-$450,000 new.
02
Larger bar (71 vs 65), bigger chucks (10-15 vs 8/6), more power (22 vs 18.5 kW), longer between-spindle (1,300 vs 885). But shorter turning (300 vs 555) and lower speed (3,500 vs 4,500-5,000).
03
Servo motor direct drive with electronic positioning for faster indexing and less maintenance.
04
Yes, 10-in chuck (12/15 opt) handles blanks, forgings, castings up to 335 mm.
