Overview

The DN Solutions PUMA 3100 is a two-axis horizontal lathe with a 12 in chuck, sized for chuck work up to 525 mm (21 in) in diameter and 790 mm (31 in) long. Its spindle is rated 26 kW (35 hp) and 1,123 N·m (828 ft-lb), with a maximum of 2,800 rpm.

Torque is the figure that defines it. For comparison, the PUMA V 400 P, a DN vertical lathe with the same chuck size and the same 26 kW (35 hp), lists 863 N·m (637 ft-lb); the PUMA 3100 has about 30% more. That reserve is for wide roughing cuts on large diameters and for big drills and boring bars working near the centreline, where spindle speed is low and the load is high. The 2,800 rpm ceiling fits the same picture. It is ample for the large diameters this envelope is meant for and limiting for small bar work.

Within the PUMA 3100 family this is the plain turning machine. The PUMA 3100 LY carries 130 mm (5 in) of Y travel and 5,000 rpm live tools on a 12-station turret, and turns 420 mm (17 in) in diameter. This model has no Y travel or live-tool row, a 10-station turret, and the larger turning diameter at 525 mm (21 in). It is also much lighter: 5,850 kg (12,897 lb) against 8,000 kg (17,637 lb) for the PUMA 3100 LY, which has 1,350 mm (53 in) of Z travel where this machine has 830 mm (33 in).

X travel is 293 mm (12 in) and rapid traverse is 30 m/min (1,181 ipm). The machine measures 3,908 × 1,978 × 2,010 mm (154 × 78 × 79 in) in length, width and height. The table says nothing about the tailstock, spindle bore or bar capacity, so those go on the list of questions for the quotation.

Strengths & Limitations

Strengths

1,123 N·m (828 ft-lb) of spindle torque from 26 kW (35 hp)
525 mm (21 in) maximum turning diameter, against 420 mm (17 in) on the Y-axis PUMA 3100 LY
790 mm (31 in) of turning length on 830 mm (33 in) of Z travel
Rapid traverse of 30 m/min (1,181 ipm)
At 5,850 kg (12,897 lb) it is far lighter to site than the 8,000 kg (17,637 lb) PUMA 3100 LY

Limitations

No Y travel or live-tool speed is listed; the PUMA 3100 LY has 130 mm (5 in) of Y and 5,000 rpm live tools
10-station turret, where the PUMA 3100 LY has 12 stations
2,800 rpm maximum limits surface speed on small diameters
Tailstock, spindle bore and bar capacity are not given in the table

Best For

Heavy roughing of steel and cast parts up to 525 mm (21 in) in diameter Chuck work up to 790 mm (31 in) long that needs turning only Large-diameter drilling and boring that draws on 1,123 N·m (828 ft-lb) Shops that send milled features to a separate machine

Frequently Asked Questions

01 Does the PUMA 3100 have a Y-axis or live tools?

Neither appears in its table. It lists X travel of 293 mm (12 in), Z travel of 830 mm (33 in) and a 10-station turret. In the same family the PUMA 3100 LY has 130 mm (5 in) of Y travel, 5,000 rpm live tools and 12 stations, with a 420 mm (17 in) turning diameter.

02 What are the spindle ratings of the PUMA 3100?

26 kW (35 hp), 1,123 N·m (828 ft-lb) and a maximum of 2,800 rpm, with a 12 in chuck. DN's table does not show the speed range over which full torque is available, so ask for the power and torque diagram if your roughing is done at very low rpm.

03 How large a workpiece can the PUMA 3100 turn?

Maximum turning diameter is 525 mm (21 in) and maximum turning length is 790 mm (31 in). X travel is 293 mm (12 in), a little more than half the turning diameter, and Z travel is 830 mm (33 in).

04 How does the PUMA 3100 compare with the PUMA 3100 SY?

The PUMA 3100 SY is listed with 30 kW (40 hp), 3,000 rpm, 130 mm (5 in) of Y travel, 5,000 rpm live tools and 12 stations, at 7,000 kg (15,432 lb). The PUMA 3100 SY turns 420 mm (17 in) by 765 mm (30 in). The PUMA 3100 turns 525 mm (21 in) by 790 mm (31 in) with 26 kW (35 hp), 2,800 rpm and 10 stations, at 5,850 kg (12,897 lb). Torque is 1,123 N·m (828 ft-lb) on both.

05 What are the installation dimensions of the PUMA 3100?

Length is 3,908 mm (154 in), width 1,978 mm (78 in) and height 2,010 mm (79 in). Machine weight is 5,850 kg (12,897 lb). A chip conveyor and coolant tank, if fitted, are not described in the table and may add to the space needed.
