Price estimate

Uncertain

We do not have a price for the Dainichi DL65/75 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 DL65/75 puts a long bed under a moderate swing. The DL65 swings 650 mm (25.6 in) over the bed and the DL75 750 mm (29.5 in), with 380 / 480 mm (15.0 / 18.9 in) over the carriage, and the distance between centres is listed from 1,000 to 8,000 mm (39.4-315.0 in). Both sizes are 2-axis (X, Z) CNC lathes.

The load rating shows what that length is for. Maximum weight between centres is 1,500 kg (3,307 lb), so an 8,000 mm (315.0 in) bed is there for slender shafts, screws and rollers, not for heavy forgings. Work like that leans on the tailstock, and the table is specific about it: an MT No. 5 centre, a 90 mm (3.5 in) quill with 110 mm (4.3 in) as an option, and 200 mm (7.9 in) of quill travel.

The spindle covers 12-1,120 min-1 in 2 gear ranges. Standard power is listed as 11 / 7.5 kW (14.8 / 10.1 hp) and the optional motor as 15 / 11 kW (20.1 / 14.8 hp). Both sizes come with an 85 mm (3.3 in) bore and can be ordered with 125 mm (4.9 in). The 175 / 254 mm (6.9 / 10.0 in) bores are for the DL75 only, and a 254 mm (10.0 in) hole through the headstock of a 750 mm (29.5 in) lathe makes it a machine for pipe ends.

A 4-jaw chuck of 450 mm (17.7 in) is standard. Machine weight runs 3,500-8,400 kg (7,716-18,519 lb), and the control is a FANUC 32i-B with an 8.4 in colour LCD. Buyers who do not need the length should compare the DL530, which is faster at 1,700 min-1 but lists only a 77 mm (3.0 in) bore.

Strengths & Limitations

Strengths

Between-centres lengths from 1,000 to 8,000 mm (39.4-315.0 in) on a 650 / 750 mm (25.6 / 29.5 in) swing
Tailstock is fully specified: MT No. 5 centre, 200 mm (7.9 in) quill travel, and an optional 110 mm (4.3 in) quill in place of the 90 mm (3.5 in) one
Optional 15 / 11 kW (20.1 / 14.8 hp) spindle power over the standard 11 / 7.5 kW (14.8 / 10.1 hp)
The DL75 can be ordered with 175 / 254 mm (6.9 / 10.0 in) spindle bores for pipe and tube
12-1,120 min-1 in 2 gear ranges, a higher top speed than the 900 min-1 of the DL95

Limitations

Load between centres is 1,500 kg (3,307 lb), low for a bed that can reach 8,000 mm (315.0 in)
The DL65 is limited to the 85 mm (3.3 in) and 125 mm (4.9 in) bores; the bigger bores are DL75 only
Swing over the carriage is 380 / 480 mm (15.0 / 18.9 in), well under the bed swing
The stronger motor, the bores above 85 mm (3.3 in) and the 110 mm (4.3 in) quill are all options

Best For

Long, slender shafts up to 8,000 mm (315.0 in) between centres Rollers and screws within the 1,500 kg (3,307 lb) load limit Pipe ends through the DL75's optional 254 mm (10.0 in) bore Irregular parts set up in the 450 mm (17.7 in) 4-jaw chuck

Frequently Asked Questions

01 What is the difference between the DL65 and the DL75?

Swing and bore options. The DL65 swings 650 mm (25.6 in) over the bed and 380 mm (15.0 in) over the carriage; the DL75 swings 750 mm (29.5 in) and 480 mm (18.9 in). Both list an 85 mm (3.3 in) bore with 125 mm (4.9 in) optional, and the 175 / 254 mm (6.9 / 10.0 in) bores are offered on the DL75 only. Speed, power and tailstock figures are given once for both.

02 How heavy a workpiece can the DL65/75 hold between centres?

1,500 kg (3,307 lb). The table gives that single figure for between-centres lengths from 1,000 to 8,000 mm (39.4-315.0 in), so the longest beds are for light, slender work. For heavier parts look at the DL95, which also brings 18.5 / 15 kW (24.8 / 20.1 hp) against the 11 / 7.5 kW (14.8 / 10.1 hp) standard here.

03 What tailstock does the DL65/75 have?

An MT No. 5 centre in a quill of 90 mm (3.5 in) diameter with 200 mm (7.9 in) of travel. A 110 mm (4.3 in) quill is listed as an option, worth considering on the long beds, where thin work depends on the tailstock for much of its support.

04 Which spindle motors are offered on the DL65/75?

Standard spindle power is listed as 11 / 7.5 kW (14.8 / 10.1 hp), with 15 / 11 kW (20.1 / 14.8 hp) as the option. The speed range is 12-1,120 min-1 in 2 gear ranges, so the low range is there for torque on bigger diameters and the high range for speed on small ones.

05 How does the DL65/75 compare with the DL530?

The DL530 is the shorter, faster machine: 1,700 min-1, 9 / 7.5 kW (12.1 / 10.1 hp), a 77 mm (3.0 in) bore and a weight of 2,800 / 3,100 kg (6,173 / 6,834 lb). The DL65/75 runs to 1,120 min-1, starts at 11 / 7.5 kW (14.8 / 10.1 hp), has an 85 mm (3.3 in) standard bore and weighs 3,500-8,400 kg (7,716-18,519 lb).
