Our best estimate for a cnc lathes / turning center in this class — not a quote from DN Solutions. Configuration moves it a long way.

Overview

Compared with the two-axis PUMA 4100 B, the DN Solutions PUMA 4100 MB trades spindle torque and a little turning length for a 12-station turret with live tools. Both are 15 in machines with a 2,000 rpm top speed, 550 mm (22 in) of turning diameter and 1,105 mm (44 in) of Z travel. What changes is everything a milling turret touches.

Start with what is gained. The live tools run to 4,000 rpm, and the turret holds 12 tools where the PUMA 4100 B holds 10. A flange can be turned, faced and bored and then have its bolt holes drilled and tapped before it is unclamped. A shaft end can get its keyway. For heavy parts this is worth more than it sounds, because every extra setup on a workpiece of this size is a crane lift and a fresh alignment.

Now the cost. The main spindle lists 30 kW (40 hp) and 1,611 N·m (1,188 ft-lb), against 35 kW (47 hp) and 2,379 N·m (1,755 ft-lb) on the PUMA 4100 B, so the two-axis machine has about 48% more torque. Maximum turning length is 978 mm (39 in) instead of the 1,042 mm (41 in) of the PUMA 4100 B. Weight rises slightly, to 10,100 kg (22,267 lb). A shop whose work is mostly hard roughing with the odd drilled hole may be better served by the two-axis machine and a separate drilling operation than by this one.

The table lists X and Z travel only. Without Y travel the rotary tools stay on the spindle centreline, which covers bolt circles, radial holes and slots but not off-centre pockets or flats milled to a dimension. Live-tool power is not stated.

X travel is 352 mm (14 in), rapids are 16 m/min (630 ipm) on X and 20 m/min (787 ipm) on Z, and DN lists the machine at 4,654 × 2,056 × 2,194 mm (183 × 81 × 86 in) as length, width and height.

Strengths & Limitations

Strengths

4,000 rpm live tools on a 15 in heavy lathe, so drilled and tapped features are done in the turning setup
12 turret stations, against 10 on the two-axis PUMA 4100 B
1,611 N·m (1,188 ft-lb) of main spindle torque at up to 2,000 rpm
550 mm (22 in) of turning diameter and 352 mm (14 in) of X travel
Same listed 4,654 × 2,056 × 2,194 mm (183 × 81 × 86 in) as the PUMA 4100 B

Limitations

Spindle is 30 kW (40 hp) and 1,611 N·m (1,188 ft-lb); the PUMA 4100 B lists 35 kW (47 hp) and 2,379 N·m (1,755 ft-lb)
Turning length falls to 978 mm (39 in) from 1,042 mm (41 in) on the PUMA 4100 B
No Y travel in the table: live tools work on the centreline only
Live-tool power and torque are not listed

Best For

Flanges and hubs up to 550 mm (22 in) that need bolt holes drilled and tapped Heavy parts where a second setup means another crane lift Short shafts up to 978 mm (39 in) with keyways or cross holes Turning within 1,611 N·m (1,188 ft-lb) on a 15 in chuck

Frequently Asked Questions

01 What do I give up by choosing the PUMA 4100 MB over the PUMA 4100 B?

Spindle power, torque and some turning length. The PUMA 4100 MB lists 30 kW (40 hp), 1,611 N·m (1,188 ft-lb) and 978 mm (39 in) of turning length. The PUMA 4100 B lists 35 kW (47 hp), 2,379 N·m (1,755 ft-lb) and 1,042 mm (41 in). In return the PUMA 4100 MB has 4,000 rpm live tools and 12 turret stations instead of 10.

02 Is the PUMA 4100 MB less capable than the 12 in PUMA 4100 MA?

It depends on the measure. The PUMA 4100 MB has the larger chuck, 15 in against 12 in, and more torque, 1,611 N·m (1,188 ft-lb) against 1,024 N·m (755 ft-lb). The PUMA 4100 MA lists more power, 37 kW (50 hp) against 30 kW (40 hp), and a higher top speed, 3,000 rpm against 2,000 rpm. The PUMA 4100 MA also turns 1,010 mm (40 in) against 978 mm (39 in).

03 Can it drill a bolt circle on a flange?

The live tools run to 4,000 rpm and, with X and Z travel only, work on the spindle centreline. A hole on a bolt circle is reached by moving the tool out in X and rotating the part to each position, so the pattern is within what a centreline tool can do. The table does not describe how the main spindle is positioned for this, and it lists neither Y travel nor live-tool power, so confirm those points with DN before sizing large drills.

04 How heavy is the PUMA 4100 MB?

10,100 kg (22,267 lb). The two-axis PUMA 4100 B weighs 9,950 kg (21,936 lb) and the 21 in PUMA 4100 C weighs 10,450 kg (23,038 lb). Listed size is 4,654 × 2,056 × 2,194 mm (183 × 81 × 86 in) as length, width and height.
