Overview

The DN Solutions PUMA 800 B II is the slowest-turning short-bed model in the PUMA 800 II family: a two-axis horizontal turning center with a 500 rpm spindle, a 900 mm (35 in) maximum turning diameter and 1,600 mm (63 in) of turning length. DN does not fix a chuck for it. The chuck row reads ORDER MADE, meaning workholding is specified with the order.

Those two rows are what set the B apart. The PUMA 800 II on the same bed is listed with a 32 in chuck and 750 rpm, and the PUMA 700 II with a 24 in chuck and 1,500 rpm. Everything else in the three columns is identical: 55 kW (74 hp), 8,076 N·m (5,957 ft-lb), 470 mm (19 in) of X travel, 1,650 mm (65 in) of Z travel, a 12-station turret and 16,500 kg (36,376 lb). The B therefore gives up speed without gaining listed torque or power, and DN's table does not say what it gets in exchange. The series description points to pipe work, with threading solutions and a spindle through hole of up to Ø375 mm. A larger bore is a common reason for a lower speed limit, but the bore of this model is not in its column and has to be confirmed.

A 500 rpm ceiling defines the work. On diameters near 900 mm (35 in) it is ample. On a small diameter it leaves carbide well short of its normal surface speed, so finishing small journals or bores will be slow. Buyers whose parts mix large and small diameters should look at the PUMA 800 II first.

Rapids are 12 m/min (472 ipm) in X and 16 m/min (630 ipm) in Z; the PUMA 800 LB II, with the same spindle speed on a 3,200 mm (126 in) bed, drops to 10 m/min (394 ipm) in Z. The machine measures 5,756 × 3,160 × 2,800 mm (227 × 124 × 110 in), length by width by height. There is no live tool row, so this is a turning-only machine.

Strengths & Limitations

Strengths

Chuck is made to order, so the workholding can be specified for the part, pipe or fixture
55 kW (74 hp) and 8,076 N·m (5,957 ft-lb) at the spindle for heavy roughing
900 mm (35 in) maximum turning diameter and 1,600 mm (63 in) turning length
Z rapid of 16 m/min (630 ipm), faster than the 10 m/min (394 ipm) of the longer PUMA 800 LB II

Limitations

500 rpm maximum spindle speed, against 750 rpm on the PUMA 800 II and 1,500 rpm on the PUMA 700 II
No listed gain in torque or power for the lower speed: the PUMA 800 II has the same 8,076 N·m (5,957 ft-lb) and 55 kW (74 hp)
No standard chuck size is listed, so the chuck has to be defined with the order before workholding can be planned
The model's column gives no spindle bore; the Ø375 mm through hole is DN's series maximum
No live tool speed is listed, so milling and cross drilling need another machine

Best For

Large-diameter turning up to 900 mm (35 in) at low spindle speeds Work that needs a chuck or fixture specified to order Heavy roughing cuts using 8,076 N·m (5,957 ft-lb) of torque Parts up to 1,600 mm (63 in) long that need turning only

Frequently Asked Questions

01 What chuck does the PUMA 800 B II come with?

DN's table gives the chuck size as ORDER MADE, so there is no standard chuck: it is specified when the machine is ordered. For reference, the PUMA 800 II on the same bed is listed with a 32 in chuck and the PUMA 700 II with a 24 in chuck. Settle the chuck, its through hole and jaw type before comparing quotations.

02 How does the PUMA 800 B II differ from the PUMA 800 II?

In two rows. The PUMA 800 B II has a made-to-order chuck and a 500 rpm spindle; the PUMA 800 II has a 32 in chuck and 750 rpm. Turning diameter, turning length, travels, rapids, 55 kW (74 hp), 8,076 N·m (5,957 ft-lb), the 12-station turret and the 16,500 kg (36,376 lb) weight are the same in both columns.

03 Is the PUMA 800 B II a big-bore pipe lathe?

The table does not say. DN describes the PUMA 600/700/800 series as offering pipe-threading solutions and a spindle through hole of up to Ø375 mm, but that is a series maximum and this model's column lists no bore. If the reason for choosing the B is bar or pipe passing through the spindle, get the bore of this exact model in writing.

04 What is the 500 rpm limit like in practice?

It suits the large end of the range: at diameters approaching 900 mm (35 in) the cutting speed is reached well below 500 rpm. On small diameters the limit keeps surface speed low and lengthens finishing passes. The spindle's 8,076 N·m (5,957 ft-lb) and 55 kW (74 hp) are available for roughing.

05 How large and heavy is the machine?

DN lists 5,756 × 3,160 × 2,800 mm (227 × 124 × 110 in), length by width by height, and a machine weight of 16,500 kg (36,376 lb). The PUMA 800 LB II, with the same 500 rpm limit and a 3,200 mm (126 in) turning length, weighs 22,000 kg (48,502 lb).
