Overview

The DN Solutions PUMA 4100 is a box-guideway horizontal lathe with 560 mm (22 in) of maximum turning diameter, listed with a 37 kW (50 hp) spindle on a 2-speed gearbox and a 12-station servo-driven turret. A machine under this exact name is not in DN Solutions' current lineup, so check the listed figures against the nameplate and manual of any machine you are considering.

The listed figures read as a family summary more than one fixed build. Turning length is 1,016 mm (40 in) as standard and up to 2,032 mm (80 in) on XL variants. Chuck options are 12, 15, 18 or 21 in. Bar capacity is 102 mm (4 in) as standard and 117 mm (4.6 in) on the M variant. Spindle speed is 2,000 rpm as standard and up to 3,000 rpm depending on the model, and the 3,282 Nm (2,419 ft-lbf) torque figure is given with the gearbox.

That spread is the thing to pin down. DN's current lettered models show how much the build matters: the PUMA 4100 B has a 15 in chuck, 2,000 rpm and 2,379 N·m (1,755 ft-lb), the PUMA 4100 C has a 21 in chuck, 1,500 rpm and 3,280 N·m (2,419 ft-lb), and the PUMA 4100 LA has a 12 in chuck, 3,000 rpm and 2,124 mm (84 in) of turning length. A bigger chuck goes with a slower, stronger spindle.

Live tooling is listed as available on M variants, with 12 stations. A hydraulic programmable tailstock and a hydraulic steady rest are listed as available too, not as standard. The control is a Fanuc 0i-TF Plus.

Strengths & Limitations

Strengths

Box guideways and a 2-speed gearbox, with 3,282 Nm (2,419 ft-lbf) of listed spindle torque
37 kW (50 hp) spindle and a 12-station servo-driven turret
Chuck options of 12, 15, 18 or 21 in and a bar capacity of 102 mm (4 in) as standard
Turning length of 1,016 mm (40 in), with up to 2,032 mm (80 in) listed on XL variants
Hydraulic programmable tailstock and hydraulic steady rest are listed as available

Limitations

Not in DN Solutions' current lineup under this name, so the listed figures need checking against the actual machine
Several rows are ranges across variants: speed is 2,000 rpm as standard and up to 3,000 rpm depending on model
Live tooling is listed only for M variants
Tailstock and steady rest are listed as available, not as standard equipment

Best For

Shaft and chucking work up to 560 mm (22 in) in diameter Bar-fed parts up to 102 mm (4 in) on the standard spindle Heavy cuts in steel using the 2-speed gearbox and 3,282 Nm (2,419 ft-lbf) Buyers assessing an existing machine who need to know which rows vary by variant

Frequently Asked Questions

01 Is the PUMA 4100 a current DN Solutions model?

Not under this plain name. DN Solutions' current lineup carries lettered models such as the PUMA 4100 B, with a 15 in chuck and 2,000 rpm, and the PUMA 4100 C, with a 21 in chuck and 1,500 rpm. The listed figures on this page cover the family more loosely, so identify the exact variant before relying on any one row.

02 What chuck sizes and bar capacity are listed for the PUMA 4100?

The listed chuck options are 12, 15, 18 and 21 in. Bar capacity is 102 mm (4 in) as standard and 117 mm (4.6 in) on the M variant. The chuck fitted also tells you a good deal about the spindle, since the larger chucks go with the lower-speed builds.

03 How long a part can it turn?

The listed maximum turning length is 1,016 mm (40 in) as standard, with up to 2,032 mm (80 in) on XL variants. Maximum turning diameter is 560 mm (22 in). For a current point of reference, the PUMA 4100 LA lists 2,124 mm (84 in) of turning length and the PUMA 4100 B lists 1,042 mm (41 in).

04 Does the PUMA 4100 have live tooling?

Only on M variants, going by the listed figures, which give 12 stations for them. The base description is a 12-station servo-driven turret. If the machine you are looking at needs to drill or mill, check for the M designation and ask for the driven-tool speed and power, which the table does not state.
