Dainichi W16L

Q: How much does the Dainichi W16L cost?

The price estimate for the Dainichi W16L is uncertain: we have no price for it that we can cite and no estimate we can stand behind, so we give no figure. Configuration, tooling, automation and installation move the final price substantially. A specific price can be requested at https://machinetoolindex.com/machines/dainichi-w16l#price; the request is passed to Dainichi or an authorised dealer.

Price estimate

Uncertain

We do not have a price for the Dainichi W16L that we can stand behind, so we show no number. Configuration, options and installation move the final price a long way: a quote is the reliable figure.

Overview

The Dainichi W16L is a 2-axis (X, Z) CNC lathe for very heavy shaft work. It carries 16,000 kg (35,274 lb) between centres, with swing over the bed listed from 1,400 to 2,200 mm (55.1-86.6 in) and distance between centres from 3,000 to 10,000 mm (118.1-393.7 in).

Everything about the spindle is sized for mass, not speed. The range is 1-250 min-1 and power is listed as 55 / 45 kW (73.8 / 60.3 hp). For scale, the DL132/152 runs to 500 min-1 on 37 / 30 kW (49.6 / 40.2 hp) and is rated for 7,500 kg (16,535 lb) between centres: the W16L turns half as fast at most and holds more than twice the weight.

The centres tell the same story. The headstock takes a 1/10 metric taper No. 80, 75 deg centre, and the tailstock a flange type #80, 75 deg centre. The standard chuck is a 4-jaw of 1,000 mm (39.4 in), and the spindle bore is 104 mm (4.1 in) with no optional bores listed.

Swing over the carriage is given as 900-1,500 mm (35.4-59.1 in). Because both swings are given as ranges, the swing has to be settled together with the bed length when the machine is specified. The table gives no machine weight, so foundation loads and transport weights must come from Dainichi with the quotation. The control is a FANUC 32i-B with an 8.4 in colour LCD.

Strengths & Limitations

Strengths

16,000 kg (35,274 lb) between centres
Swing over the bed from 1,400 to 2,200 mm (55.1-86.6 in) and over the carriage from 900 to 1,500 mm (35.4-59.1 in)
55 / 45 kW (73.8 / 60.3 hp) spindle power, above the 37 / 30 kW (49.6 / 40.2 hp) of the DL132/152
Speed range starts at 1 min-1, useful when setting and clocking very heavy parts
Large centres: 1/10 metric taper No. 80, 75 deg at the headstock and flange type #80, 75 deg at the tailstock

Limitations

Spindle speed is limited to 250 min-1, half the 500 min-1 of the DL132/152
Shortest listed distance between centres is 3,000 mm (118.1 in), so it is not offered as a short-bed machine
Spindle bore is 104 mm (4.1 in) with no optional sizes in the table; the DL120 lists optional bores up to 425 mm (16.7 in)
No machine weight is listed, so installation planning depends on data requested from Dainichi

Best For

Rolls, rotors and shafts up to 16,000 kg (35,274 lb) between centres Diameters up to 1,500 mm (59.1 in) over the carriage on the largest swing Long heavy work between 3,000 and 10,000 mm (118.1-393.7 in) centres Slow, heavy roughing with 55 / 45 kW (73.8 / 60.3 hp) at up to 250 min-1

Frequently Asked Questions

01 How much weight can the W16L hold between centres?

16,000 kg (35,274 lb). That is more than twice the 7,500 kg (16,535 lb) rating of the DL132/152. The load sits on a 1/10 metric taper No. 80, 75 deg centre in the headstock and a flange type #80, 75 deg centre in the tailstock, or in the standard 4-jaw chuck of 1,000 mm (39.4 in).

02 What swing does the W16L have?

The table gives ranges, not single values: 1,400-2,200 mm (55.1-86.6 in) over the bed and 900-1,500 mm (35.4-59.1 in) over the carriage. It does not name the individual sizes within those ranges, so state the largest diameter you need over the carriage when asking for a quotation.

03 What spindle speed and power does the W16L offer?

The spindle runs 1-250 min-1 and power is listed as 55 / 45 kW (73.8 / 60.3 hp). No gear ranges or optional motors are shown in the table. A 250 min-1 limit suits diameters near the 900-1,500 mm (35.4-59.1 in) carriage swing and rules out fast finishing on small journals.

04 How long can a part be on the W16L?

Distance between centres is listed from 3,000 to 10,000 mm (118.1-393.7 in). The spindle bore is 104 mm (4.1 in), so long stock cannot pass through the headstock unless it is smaller than that. Longer beds are listed on the DL132/152, which is rated for 7,500 kg (16,535 lb) between centres.
