Overview

The DN Solutions PUMA 3100 SY is a 12 in Y-axis turning center with a sub-spindle: 420 mm (17 in) of turning diameter, 765 mm (30 in) of turning length, a 12-station turret with 5,000 rpm live tools and a second spindle that runs to 4,000 rpm. Among the short-bed machines of the range it is the one that can take a part off the main chuck and machine its back face without an operator turning it round.

The main spindle carries the higher of the two ratings DN uses in this family. It lists 30 kW (40 hp), 1,123 N·m (828 ft-lb) and 3,000 rpm, where the PUMA 3100 Y without the second spindle lists 26 kW (35 hp) and 2,800 rpm at the same torque. A torque figure of that size is meant for heavy cuts in steel at larger diameters, and the 3,000 rpm ceiling means small-diameter finishing runs at a modest surface speed.

Y travel is 130 mm (5 in), alongside 293 mm (12 in) of X and 830 mm (33 in) of Z. That stroke lets the 5,000 rpm rotary tools cut off-centre holes, flats and keyways, which is the point of pairing a Y axis with a sub-spindle: turned and milled features on both ends in one cycle. For the sub-spindle the table gives a speed and nothing else. Its chuck size, power and bore are not listed, so check them against the second-operation work you have in mind.

With 830 mm (33 in) of Z travel shared between two spindles, this is a machine for chucked parts and short shafts. The PUMA 3100 LSY keeps the same main spindle rating, Y travel and turret and stretches Z to 1,350 mm (53 in) and turning length to 1,285 mm (51 in), at 8,500 kg (18,739 lb) against 7,000 kg (15,432 lb) here. Rapids are 30 m/min (1,181 ipm), and the machine measures 3,908 × 1,978 × 2,315 mm (154 × 78 × 91 in) as length, width and height.

Strengths & Limitations

Strengths

Sub-spindle running to 4,000 rpm, so the back of a part can be machined in the same cycle
130 mm (5 in) of Y travel with 5,000 rpm live tools on a 12-station turret
30 kW (40 hp) main spindle at 3,000 rpm, against 26 kW (35 hp) and 2,800 rpm on the PUMA 3100 Y
1,123 N·m (828 ft-lb) of main spindle torque on a 12 in chuck
Listed at the same 3,908 × 1,978 × 2,315 mm (154 × 78 × 91 in) as the PUMA 3100 Y, so the second spindle adds no length to the installation

Limitations

Turning length is 765 mm (30 in); the PUMA 3100 LSY reaches 1,285 mm (51 in) with the same main spindle rating
Turning diameter is 420 mm (17 in), against 525 mm (21 in) on the two-axis PUMA 3100
The table gives only a speed for the sub-spindle: no chuck size, power or torque is listed for it
The main spindle tops out at 3,000 rpm, which limits surface speed on small diameters

Best For

Chucked parts finished on both ends in one cycle using the 4,000 rpm sub-spindle Off-centre drilling and milling within 130 mm (5 in) of Y travel Steel parts up to 420 mm (17 in) in diameter that need 1,123 N·m (828 ft-lb) Shops removing a second-operation lathe or mill from the route

Frequently Asked Questions

01 What is the difference between the PUMA 3100 SY and the PUMA 3100 Y?

The sub-spindle and the main spindle rating. The PUMA 3100 SY lists a sub-spindle speed of 4,000 rpm and a main spindle of 30 kW (40 hp) at 3,000 rpm. The PUMA 3100 Y has no sub-spindle row in its table and lists 26 kW (35 hp) at 2,800 rpm. Torque is 1,123 N·m (828 ft-lb) on both, as are the travels, the 12-station turret and the 5,000 rpm live tools. The PUMA 3100 SY weighs 7,000 kg (15,432 lb) against 6,500 kg (14,330 lb).

02 How large a part does the PUMA 3100 SY take?

Maximum turning diameter is 420 mm (17 in) and maximum turning length is 765 mm (30 in), on a 12 in main chuck. Travels are 293 mm (12 in) in X, 130 mm (5 in) in Y and 830 mm (33 in) in Z. For longer parts with the same main spindle rating the PUMA 3100 LSY turns 1,285 mm (51 in).

03 What does the table say about the sub-spindle?

Only its top speed, 4,000 rpm. DN's table for this model gives no chuck size, power, torque or bore for the second spindle. Those figures decide how heavy a second-operation cut can be and what diameter the sub-spindle can grip, so ask for them before planning back-face work beyond light turning, drilling and milling.

04 What can the Y-axis and live tools do on this machine?

The turret has 12 stations and its live tools run to 5,000 rpm. With 130 mm (5 in) of Y travel a rotary tool can move off the spindle centreline, which is what allows flats milled to a width, off-centre holes and keyways cut with the side of an end mill. The table does not give live-tool power or torque, so confirm the largest drill or cutter you intend to run.

05 How much space and floor load does the PUMA 3100 SY need?

DN lists 3,908 × 1,978 × 2,315 mm (154 × 78 × 91 in) as length, width and height and a machine weight of 7,000 kg (15,432 lb). The listed dimensions cover the machine itself; allow extra room for chip handling, service access and the operator.
