Length. Both are listed at 640 mm (25.2 in) of turning diameter, the same main-spindle speed of 4,500 rpm and the same 15 / 11 kW power. The NTRX-300 turns 1,100 mm (43.3 in) long; the NTRX-300L turns 1,600 mm (63 in).
An upper milling spindle rated 15 kW (20 hp) with 24 tools as standard and 40 or 80 optional, plus a lower turret with 12 stations and driven tools at 5,000 RPM.
The sub-spindle runs to 2,500 rpm and is rated 15 kW (20 hp). The main spindle runs to 4,500 rpm. Plan small-diameter finishing on the main side where possible.
Chucks of 8 in and 10 in are listed, with 12 in and 15 in and up as options. Bar capacity is 65 mm (2.6 in) as standard, 71 mm (2.8 in) or 80 mm (3.1 in) with options, and 90 mm (3.5 in) on the L spindle only.
