Overview

The Nakamura-Tome NTJ-100 is a 6 in chuck machine (8 in optional) that turns up to 175 mm (6.9 in) in diameter and 678 mm (26.7 in) in length. Its spindle runs to 5,000 rpm on an 11 / 7.5 kW drive motor and passes 51 mm (2 in) bar, or 65 mm (2.6 in) with the Ø65 mm option, which lowers top speed to 4,500 rpm.

The length is the notable figure. The Super NTJ, listed at 190 mm (7.5 in) of diameter and 620 mm (24.4 in) of length with a 15 / 11 kW spindle, takes slightly larger diameters, but the NTJ-100 turns the longer part. The table lists no turret or tool-station figures for the NTJ-100, so get the tooling layout from Nakamura-Tome before comparing the two on cycle time.

The machine measures 3,799 × 2,110 × 2,565 mm (W × D × H).

Frequently Asked Questions

01 How does the NTJ-100 compare with the Super NTJ?

The Super NTJ is listed at 190 mm (7.5 in) of turning diameter and 620 mm (24.4 in) of length, with a 15 / 11 kW spindle. The NTJ-100 turns 175 mm (6.9 in) in diameter and 678 mm (26.7 in) long on 11 / 7.5 kW, so it suits longer, slimmer parts.

02 What bar capacity does the NTJ-100 have?

51 mm (2 in) as standard at 5,000 rpm. The Ø65 mm option raises bar capacity to 65 mm (2.6 in) and limits top speed to 4,500 rpm. A 6 in chuck is standard and an 8 in chuck is optional.
