Our best estimate for a cnc lathes / turning center in this class — not a quote from DN Solutions. Configuration moves it a long way.

Overview

The DN Solutions PUMA 4100L is listed as a long-bed heavy lathe: 4,000 mm (157.5 in) of maximum turning length, a 1,000 mm (39.4 in) swing over the bed and 800 mm (31.5 in) of turning diameter over the cross slide. No machine of this exact name is in DN Solutions' current lineup, and the listed figures should be confirmed against the builder's documents for any machine offered under it.

On paper it is a machine for long shafts and tube. The spindle is listed at 45 kW (60 hp) with a 3 to 1,000 rpm range and torque given as 5,000+ Nm (3,688+ ft-lb), on an A2-15 / D1-15 nose with a bar capacity of 130 mm (5.12 in). Low speed and a large bore point to heavy, slender work such as rolls, drive shafts and long tubes. The support equipment in the table fits that picture, with a programmable tailstock on an MT6 centre taper and multiple CNC-integrated programmable steady rests.

These figures sit a long way from DN's current lettered models. The PUMA 4100 LA, for example, lists a 12 in chuck, 550 mm (22 in) of turning diameter, 2,124 mm (84 in) of turning length and 10,900 kg (24,030 lb), against roughly 35,000 kg (77,162 lb) listed here. A buyer should not assume the two share anything beyond the name.

The turret is listed with 8 or 12 stations and live tooling as an option. Z rapid traverse is 12 m/min (472 ipm), and no X rapid or X travel is given. The control is a Fanuc 32i-B.

Strengths & Limitations

Strengths

4,000 mm (157.5 in) of listed turning length with multiple programmable steady rests
1,000 mm (39.4 in) swing over the bed and 800 mm (31.5 in) over the cross slide
130 mm (5.12 in) bar capacity on an A2-15 / D1-15 spindle nose
45 kW (60 hp) spindle with torque listed as 5,000+ Nm (3,688+ ft-lb)
Programmable tailstock with an MT6 centre taper

Limitations

Not in DN Solutions' current lineup under this name; the listed figures need confirming for any specific machine
The spindle range tops out at 1,000 rpm
Live tooling is optional, and the turret is listed as 8 or 12 stations without saying which is standard
Weight is listed at approximately 35,000 kg (77,162 lb), which sets foundation and rigging requirements
X travel and X rapid are not stated

Best For

Long shafts and rolls up to 4,000 mm (157.5 in) Slender work that needs more than one steady rest Tube and bar up to 130 mm (5.12 in) through the spindle Low-speed heavy turning up to 800 mm (31.5 in) over the cross slide

Frequently Asked Questions

01 How long a workpiece does the PUMA 4100L take?

The listed maximum turning length is 4,000 mm (157.5 in). Swing over the bed is 1,000 mm (39.4 in) and turning diameter over the cross slide is 800 mm (31.5 in). Multiple CNC-integrated programmable steady rests and a programmable tailstock with an MT6 centre taper are listed for supporting work of that length.

02 Is the PUMA 4100L the same machine as the PUMA 4100 LA?

The listed figures say no. The PUMA 4100 LA in DN's current range has a 12 in chuck, 550 mm (22 in) of turning diameter, 2,124 mm (84 in) of turning length, a 3,000 rpm spindle and a weight of 10,900 kg (24,030 lb). The PUMA 4100L is listed at 4,000 mm (157.5 in) of turning length, 1,000 rpm and about 35,000 kg (77,162 lb).

03 What spindle does the PUMA 4100L have?

A 45 kW (60 hp) spindle with a listed range of 3 to 1,000 rpm and torque given as 5,000+ Nm (3,688+ ft-lb). The nose is A2-15 / D1-15 and bar capacity is 130 mm (5.12 in). The torque figure is open-ended as listed, so ask for the torque curve of the actual machine.

04 Does it have live tooling?

Live tooling is listed as optional. The turret is given as 8 or 12 stations. Driven-tool speed and power are not in the table, so a machine fitted with the option needs those figures from its own documentation.
