Overview

The Nakamura-Tome WTW-300 is listed as a large twin-spindle turning center: a 37 kW main spindle and a 22 kW sub-spindle, both to 4,000 rpm and both carrying 300 mm (12 in) chucks, over a turning envelope of 340 mm diameter and 1,000 mm length. Bar capacity is listed at 76 mm (3 in). This model does not appear on Nakamura-Tome's current product pages, so check the listed figures against the machine you are offered.

Each of the turrets has 12 stations, live tooling runs to 6,000 rpm, and every turret is listed with a Y-axis stroke of ±52 mm. With Y on both turrets, off-centre holes and flats can be cut on either spindle, which is what lets a part come off finished on both ends. The control is listed as NT Smart X.

The gap between the two spindles is the point to weigh. The main spindle has 37 kW for roughing from bar or chucked blanks, while the sub-spindle's 22 kW suits finishing and lighter back-end work. Having 300 mm (12 in) chucks on both sides means a heavy part can be handed over without changing jaws to a smaller size, and the 1,000 mm turning length takes long shafts.

Strengths & Limitations

Strengths

37 kW main spindle with a 300 mm (12 in) chuck and 76 mm (3 in) bar capacity
Sub-spindle also takes a 300 mm (12 in) chuck, so heavy parts can be transferred for the second operation
Y-axis stroke of ±52 mm listed on each turret
12 stations per turret with live tooling to 6,000 rpm
1,000 mm turning length and 340 mm turning diameter for long shafts

Limitations

Both spindles top out at 4,000 rpm, slow for small diameters
The sub-spindle is rated 22 kW against 37 kW on the main, so heavy cuts belong on the main side
12 stations per turret limits how many different tools a complex part can use without re-tooling
Not on Nakamura-Tome's current product pages; the listed figures need checking against the machine itself

Best For

Long shafts up to 1,000 mm with milled features on both ends Bar work up to 76 mm (3 in) in one cycle Heavy chucked parts handed between two 300 mm (12 in) chucks Off-centre drilling and milling with ±52 mm of Y on each turret

Frequently Asked Questions

01 How do the WTW-300's two spindles compare?

Both are listed to 4,000 rpm and both take 300 mm (12 in) chucks. The main spindle is rated 37 kW and the sub-spindle 22 kW, so plan roughing on the main side and use the sub-spindle for back-end finishing and lighter cuts.

02 Does the WTW-300 have a Y-axis?

Yes. The listed figures give a Y-axis stroke of ±52 mm per turret, and each turret has 12 stations with live tooling to 6,000 rpm. That covers off-centre holes, flats and keyways on parts held in either spindle.

03 What size work fits the WTW-300?

Parts up to 340 mm in diameter and 1,000 mm in length, with bar up to 76 mm (3 in) and 300 mm (12 in) chucks on both spindles. Confirm these listed figures on the machine itself, since this model is not on Nakamura-Tome's current product pages.

04 Which control does the WTW-300 use?

The listed control is NT Smart X. Because this model is not among Nakamura-Tome's current machines, confirm the control and its version on the actual machine before you rely on programs written for it.
