Overview

The DN Solutions PUMA 3100 Y is the short-bed Y-axis lathe in the PUMA 3100 range: a 12 in chuck, 420 mm (17 in) of maximum turning diameter, 765 mm (30 in) of turning length and 130 mm (5 in) of Y travel. The turret has 12 stations and its live tools run to 5,000 rpm.

It is easiest to judge next to the two-axis machine of the same size. The PUMA 3100 has the same 12 in chuck and the same travels of 293 mm (12 in) in X and 830 mm (33 in) in Z. The PUMA 3100 turns 525 mm (21 in) in diameter and 790 mm (31 in) in length, carries a 10-station turret and weighs 5,850 kg (12,897 lb). Against that, the Y-axis version gives up turning diameter and a little length. In return it gains two turret stations, driven tools and a third linear axis, at 6,500 kg (14,330 lb). The spindle rating is identical in both tables: 26 kW (35 hp), 1,123 N·m (828 ft-lb) and 2,800 rpm.

That makes the part mix the deciding question. Plain turned work above 420 mm (17 in) belongs on the two-axis machine. Parts that leave the lathe and then queue for a mill, for a keyway, a pair of flats, a cross hole off the centreline or a drilled pattern on a face, are where the Y axis pays. With 130 mm (5 in) of stroke the tool can be offset to either side of centre, so features are cut to position and width in the program instead of being limited to what a tool on the centreline can reach.

Two things the table leaves open. It gives the live-tool speed but not the power or torque behind it, which sets how large a drill or end mill is sensible. And it lists no sub-spindle, so the back of the part is a second setup. The PUMA 3100 SY, with a sub-spindle listed at 4,000 rpm and a 30 kW (40 hp) main spindle, covers that case on the same bed length.

Rapids are 30 m/min (1,181 ipm). The machine measures 3,908 × 1,978 × 2,315 mm (154 × 78 × 91 in) as length, width and height.

Strengths & Limitations

Strengths

130 mm (5 in) of Y travel on a 12 in lathe, for off-centre milling and drilling
12-station turret with live tools to 5,000 rpm, against 10 stations on the two-axis PUMA 3100
1,123 N·m (828 ft-lb) of spindle torque from 26 kW (35 hp), the same rating as the two-axis PUMA 3100
30 m/min (1,181 ipm) rapid traverse
Machine weight of 6,500 kg (14,330 lb), against 8,000 kg (17,637 lb) for the long-bed PUMA 3100 LY

Limitations

Turning diameter drops to 420 mm (17 in) from 525 mm (21 in) on the two-axis PUMA 3100
Spindle speed stops at 2,800 rpm; the PUMA 3100 SY lists 3,000 rpm and 30 kW (40 hp)
No sub-spindle is listed, so back-face work needs a second setup
Turning length is 765 mm (30 in); longer parts need the PUMA 3100 LY at 1,285 mm (51 in)

Best For

Chucked parts and short shafts up to 420 mm (17 in) in diameter with milled features Off-centre holes, flats and keyways within 130 mm (5 in) of Y travel Combining turning and a milling operation in one setup Steel turning that calls for 1,123 N·m (828 ft-lb) at low speed

Frequently Asked Questions

01 What does the PUMA 3100 Y add over the two-axis PUMA 3100?

A Y axis with 130 mm (5 in) of travel, live tools running to 5,000 rpm and a 12-station turret where the PUMA 3100 has 10 stations. The PUMA 3100 turns a larger part, 525 mm (21 in) by 790 mm (31 in) against 420 mm (17 in) by 765 mm (30 in) on the PUMA 3100 Y. Both list the same spindle: 26 kW (35 hp), 1,123 N·m (828 ft-lb) and 2,800 rpm.

02 Does the PUMA 3100 Y have a sub-spindle?

The table for the PUMA 3100 Y lists no sub-spindle. The PUMA 3100 SY is the version with one: it lists a sub-spindle speed of 4,000 rpm, a 30 kW (40 hp) main spindle at 3,000 rpm and a machine weight of 7,000 kg (15,432 lb), with the same turning diameter, turning length and travels as this model.

03 What size of part fits the PUMA 3100 Y?

Up to 420 mm (17 in) in turning diameter and 765 mm (30 in) in turning length on a 12 in chuck. X travel is 293 mm (12 in) and Z travel is 830 mm (33 in). If length is the constraint, the PUMA 3100 LY keeps the same spindle and Y travel and turns 1,285 mm (51 in) on 1,350 mm (53 in) of Z.

04 Is the spindle suited to small, fast work?

It is built the other way. The spindle lists 1,123 N·m (828 ft-lb) and 26 kW (35 hp) with a top speed of 2,800 rpm, which favours heavy cuts at larger diameters. On small diameters 2,800 rpm gives a low surface speed. The 5,000 rpm live tools are the faster spindle on the machine, for drills and end mills.

05 How big and heavy is the PUMA 3100 Y?

DN lists 3,908 × 1,978 × 2,315 mm (154 × 78 × 91 in) as length, width and height, and 6,500 kg (14,330 lb) of machine weight. The two-axis PUMA 3100 weighs 5,850 kg (12,897 lb). Leave room beyond the listed dimensions for chip handling and service access.
