Overview

The Nakamura-Tome WY-250L is a two-spindle turning center built for length, with 910 mm (35.8 in) of turning length and 225 mm (8.9 in) of turning diameter. The left spindle is rated 18.5/11 kW at 4,500/3,500 RPM on an 8 in chuck and passes 65 mm (2.6 in) bar; the right spindle is rated 15/11 kW at 5,000/4,500 RPM on a 6 in chuck and passes 51 mm (2 in). Tool capacity is up to 48, and driven tools are rated 5.5/3.7 kW at 6,000 RPM.

The spindle upgrades are coupled. Ordering the optional 26/22 kW left spindle automatically brings the right spindle up to 18.5/15 kW, and ordering the 18.5/15 kW right spindle automatically brings the left to 26/22 kW. In practice the machine comes in two power levels rather than four combinations, and the higher one gives a right spindle strong enough for real second-operation cutting.

Larger bores are listed for both sides. On the right, the Ø65 mm option takes bar to 65 mm (2.6 in) and limits that spindle to 4,500 rpm. On the left, the table lists bar capacities of 71 mm (2.8 in) and 80 mm (3.1 in) for the bigger-bore builds, with top speed dropping to 3,500 rpm on the Ø71 mm option, and turning diameter falling to 180 mm (7.1 in) with the Ø80 mm option. The option labels in this table are not consistent, so have Nakamura-Tome confirm the exact bore, speed and diameter for the build you quote.

At 4,620 × 2,593 × 2,563 mm (W × D × H) it is a large footprint for a 225 mm (8.9 in) swing. The extra length over the WY-150V, which turns 685 mm (27 in) long, is what you pay floor space for: shafts, tubes and long bar parts that would not fit between the spindles of the shorter machine.

Strengths & Limitations

Strengths

910 mm (35.8 in) turning length for long shafts and tubes
Left spindle 18.5/11 kW at 4,500/3,500 RPM with an 8 in chuck and 65 mm (2.6 in) bar
Optional 26/22 kW left spindle comes with the right spindle upgraded to 18.5/15 kW
Right spindle rated 15/11 kW as standard, close to the 18.5/11 kW of the left spindle
Tool capacity of up to 48 with 5.5/3.7 kW driven tools

Limitations

Driven tools run to only 6,000 RPM, against 10,000 RPM on the WY-150V
Left spindle tops out at 4,500 rpm, limiting surface speed on small diameters
Right spindle takes a 6 in chuck and 51 mm (2 in) bar as standard
The Ø80 mm option cuts turning diameter to 180 mm (7.1 in)
4,620 × 2,593 × 2,563 mm (W × D × H) needs a large floor area

Best For

Shafts and long bar parts up to 910 mm (35.8 in) Bar work up to 65 mm (2.6 in) finished on both ends Second operations that need real power on the right spindle Parts up to 225 mm (8.9 in) in diameter with drilled and milled features

Frequently Asked Questions

01 What is the difference between the WY-250L and the WY-150V?

Length and speed. The WY-250L turns 910 mm (35.8 in) long on an 8 in chuck with a 4,500 rpm left spindle and 6,000 RPM driven tools. The WY-150V turns 685 mm (27 in) long, runs both spindles to 6,000 rpm and drives tools at up to 10,000 RPM. Both are listed at 225 mm (8.9 in) of turning diameter.

02 How do the WY-250L spindle upgrades work?

They come as a pair. The optional 26/22 kW left spindle automatically upgrades the right spindle to 18.5/15 kW, and choosing the 18.5/15 kW right spindle automatically upgrades the left to 26/22 kW. Standard ratings are 18.5/11 kW left and 15/11 kW right.

03 What bar sizes can the WY-250L take?

The left spindle takes 65 mm (2.6 in) as standard and the right spindle 51 mm (2 in). The Ø65 mm right-spindle option raises the right side to 65 mm (2.6 in) at 4,500 rpm. Larger-bore left-spindle builds are listed with 71 mm (2.8 in) and 80 mm (3.1 in) bar, at lower top speeds.

04 What chucks does the WY-250L use?

The table lists an 8 in chuck for the main spindle and a 6 in chuck for the sub-spindle. If the second operation grips a large diameter, check that the 6 in chuck covers it before choosing this machine.
