Overview

The DN Solutions PUMA 3100 LSY combines a Y-axis, live tools and a sub-spindle on the long PUMA 3100 bed. It is a 12 in chuck lathe with 130 mm (5 in) of Y travel, 5,000 rpm live tools, a 4,000 rpm sub-spindle and 1,350 mm (53 in) of Z travel, turning up to 1,285 mm (51 in) in length and 420 mm (17 in) in diameter.

A second spindle changes what leaves the machine. The part is handed over, its back face and bore are machined, and it comes out complete instead of going to a second operation. How much of that back-end work is realistic depends on figures DN's table leaves out: it gives the sub-spindle's speed and nothing about its power, torque or chuck. Get those first. A sub-spindle strong enough only for finishing forces most of the stock removal onto the main side.

The main spindle is the stronger of the two long-bed ratings. It lists 30 kW (40 hp) and 3,000 rpm, where the PUMA 3100 LY lists 26 kW (35 hp) and 2,800 rpm. Torque is 1,123 N·m (828 ft-lb) on both, so the additional power shows up in the upper half of the speed range, not in low-speed roughing.

The Y-axis is what lets the 12-station turret mill flats, off-centre holes and pockets, and DN's series text ties complex shapes to the Y-axis models. The table gives the stroke as a single 130 mm (5 in) figure without saying how it divides about the centreline. X travel is 293 mm (12 in) and rapids are 30 m/min (1,181 ipm).

All of this makes a large machine: 8,500 kg (18,739 lb) and 4,530 × 2,067 × 2,315 mm (178 × 81 × 91 in), length by width by height. If the parts are short, the PUMA 3100 SY has the same 30 kW (40 hp) and 3,000 rpm on 830 mm (33 in) of Z travel and weighs 7,000 kg (15,432 lb).

Strengths & Limitations

Strengths

4,000 rpm sub-spindle for machining the back of the part in the same cycle
30 kW (40 hp) main spindle with 1,123 N·m (828 ft-lb) and 3,000 rpm
130 mm (5 in) of Y travel with 5,000 rpm live tools on a 12-station turret
1,285 mm (51 in) of turning length on 1,350 mm (53 in) of Z travel
More power and speed than the PUMA 3100 LY, which lists 26 kW (35 hp) and 2,800 rpm

Limitations

The table gives only the speed of the sub-spindle, with no power, torque or chuck size
Turning diameter is 420 mm (17 in), against 525 mm (21 in) on the two-axis PUMA 3100
At 8,500 kg (18,739 lb) it is the heaviest of the PUMA 3100 models listed here
Live-tool power and torque are not stated
12 stations have to hold turning tools and driven tools for both spindles

Best For

Long parts finished on both ends without a second setup Shafts up to 1,285 mm (51 in) with off-centre milled features Work that uses 30 kW (40 hp) at medium and high spindle speeds Complete machining of parts up to 420 mm (17 in) in diameter

Frequently Asked Questions

01 What does the sub-spindle on the PUMA 3100 LSY offer?

The table lists it at 4,000 rpm, faster than the 3,000 rpm main spindle. It gives no power, torque or chuck size for it. Before planning heavy cuts on the second side, ask DN for those ratings and for the largest diameter the sub-spindle can grip.

02 How does the PUMA 3100 LSY differ from the PUMA 3100 LY?

Travels, turning envelope, 12 stations and 5,000 rpm live tools match. The PUMA 3100 LSY lists 30 kW (40 hp), 3,000 rpm and 8,500 kg (18,739 lb), and its table has a 4,000 rpm sub-spindle row. The PUMA 3100 LY lists 26 kW (35 hp), 2,800 rpm and 8,000 kg (17,637 lb). Both give 1,123 N·m (828 ft-lb).

03 How much Y-axis travel is there?

130 mm (5 in). The table states the total stroke only, so the reach above and below the spindle centreline should be confirmed if a feature sits far off-centre. Live tools run to 5,000 rpm.

04 Is the PUMA 3100 LSY the right size for short parts?

It will run them, but the bed is long for the job. Z travel is 1,350 mm (53 in) and the machine is 4,530 mm (178 in) long. The PUMA 3100 SY has 830 mm (33 in) of Z travel and 765 mm (30 in) of turning length with the same 30 kW (40 hp) and 3,000 rpm, at 7,000 kg (15,432 lb).

05 What must the workshop provide for a PUMA 3100 LSY?

Room for 4,530 × 2,067 × 2,315 mm (178 × 81 × 91 in) as length, width and height, and a floor and lifting plan for 8,500 kg (18,739 lb). Electrical and air requirements are not in the table; request the installation data sheet.
