PUMA GT/DNT Series

The PUMA GT/DNT series is DN Solutions (formerly Doosan Machine Tools) Global Turning family of horizontal turning centers. These heavy-duty, box guideway machines have an 8” or 10″ chuck and a powerful 15.5 – 18.5kW/4500 rpm or 26kW/3500 rpm spindle depending on the model type. Designed to meet global standards, the GT Series will keep you competitive and productive.

What Is the PUMA DNT2600 Turning Center?

The PUMA DNT2600 is a DN Solutions horizontal turning center built for heavy and interrupted cutting, long-term high accuracy, and superior surface finishes. It holds an 18.1 in. maximum turning diameter and a 26 kW (35 HP) spindle rated to 3,500 RPM, with an oversized spindle bore and draw tube that accept bar stock up to 3.19 in. in diameter. A 12-station servo-controlled turret indexes in 0.15 seconds to keep non-cutting time low, and the machine runs on a FANUC 0i-Plus control with iHMi touch screen interface. Ellison Technologies, the largest DN Solutions distributor in North America, supplies the DNT2600 as part of its full turning center lineup for shops running large-diameter shafts and heavy stock removal.

Energy and Oil & Gas Components

Heavy-wall shafts, flanges, and drilling components demand a machine that holds tolerance through interrupted cuts on forged and cast material, exactly what the DNT2600's rigid 30-degree slant bed and 735 Nm (542 ft-lb) of spindle torque are built for. Shops supplying energy and oil & gas manufacturers use the DNT2600's 18.1 in. turning diameter and 3.19 in. bar capacity to run large-diameter components in fewer setups, with the airbag-function torque detection protecting the ball screw when interrupted cuts hit hard spots in forged stock.

Heavy Agricultural and Off-Highway Equipment

Axles, hubs, and drive components for agriculture and off-highway equipment are typically large-diameter, interrupted-cut parts run in batches, a fit for the DNT2600's 25.9 in. maximum turning length and high-torque digital AC spindle motor. The wide box-way construction and induction-hardened guideways hold accuracy over long production runs without the wear that shortens tool life on lighter-duty lathes.

Automotive and Heavy Industrial Shaft Work

Drivetrain shafts and heavy industrial components for automotive suppliers benefit from the DNT2600's fast 1,181 ipm Z-axis rapid traverse and 0.15-second turret indexing, which cut non-cutting time on high-volume shaft work. The programmable hydraulic tailstock and MT #5 live center support long, slender parts without sacrificing the rigidity heavy roughing passes require.

FAQ Section

What is the PUMA DNT2600 used for?

The PUMA DNT2600 is a high-performance CNC turning center used for heavy and interrupted cutting on large-diameter parts, shafts, flanges, hubs, and bar-fed components up to 3.19 in. in diameter. Its rigid slant-bed construction and 26 kW (35 HP) spindle are built for shops that need long-term accuracy under heavy stock removal, not light-duty finishing work.

How does the PUMA DNT2600 compare to the PUMA DNT2100?

The DNT2600 steps up from the PUMA DNT2100 with a larger 18.1 in. maximum turning diameter, a 3,500 RPM spindle rated to 26 kW (35 HP), and a bigger 10 in. standard chuck, making it the better fit for larger-diameter shaft and flange work where the DNT2100 is sized for smaller parts.

What industries is the PUMA DNT2600 best suited for?

The DNT2600's combination of large turning diameter, heavy bar capacity, and interrupted-cutting rigidity fits energy and oil & gas component manufacturing, heavy agricultural and off-highway equipment production, and automotive drivetrain shaft work, anywhere large, heavy-wall parts need to hold tolerance through repeated setups.

What is the maximum bar capacity of the PUMA DNT2600?

The PUMA DNT2600 accepts bar stock up to 3.19 in. (81 mm) in diameter through its oversized spindle bore and draw tube, with a maximum bar length of 36 in. for bar-feed applications.

What control does the PUMA DNT2600 run?

The PUMA DNT2600 uses a FANUC 0i-Plus control with an iHMi touch screen interface and swiveling operator's panel, including EZ Guide i conversational programming for shop-floor programming without a predefined tool database
