Overview
The DN Solutions PUMA DNT 2600 LM is the long-bed milling variant in the DNT 2600 turning center lineup, giving you live tooling and extended Z-axis travel in a single-turret platform. If you've been farming out secondary milling ops on turned parts, this machine lets you keep everything under one roof. It's built for shops that need to turn shafts, drill cross-holes, and mill flats without reclamping in a VMC.
The main spindle packs 26 kW (34.9 hp) with 735 Nm (542 ft-lb) of torque and tops out at 3,500 RPM through a 10-12 inch chuck. That's serious grunt for mid-range production turning in steel, stainless, and alloy materials. The long-bed configuration gives you 1,100 mm (43.3 in) of Z-axis travel and 1,030 mm (40.5 in) of max turning length, so you can handle longer shafts and components that won't fit on the standard-bed 2600 M.
X-axis travel is 260 mm (10.2 in) with rapids at 24 m/min on X and 30 m/min on Z. The 12-station turret runs live tools at 6,000 RPM, giving you enough speed for drilling, tapping, and light milling operations. It won't replace a dedicated machining center for heavy milling, but for cross-holes, keyways, and flats, it gets the job done in the same setup.
The FANUC 0i-TF Plus control is the industry workhorse. Every service tech knows it, every operator's seen it, and programming is straightforward whether you're running conversational or straight G-code. At roughly 4,950 kg (10,913 lb), this isn't a lightweight machine, and that mass works in your favor for vibration damping on heavy cuts.
For shops running a mix of shafts, couplings, and hydraulic components that need both turning and secondary milling, the DNT 2600 LM hits the sweet spot between capability and cost. It won't replace a full mill-turn with Y-axis, but for C-axis milling work, it's a strong value proposition.

Strengths & Limitations
Strengths
- Long-bed Z-axis travel of 1,100 mm (43.3 in) handles shafts and components that won't fit on standard-bed lathes
- 26 kW spindle with 735 Nm of torque handles heavy roughing in steel and stainless without bogging down
- Live tooling at 6,000 RPM eliminates secondary ops for cross-holes, keyways, and flats
- 12-station turret provides enough tool capacity for complex parts without manual tool changes
- FANUC 0i-TF Plus control is the industry standard with universal operator familiarity and easy service
- DNT-generation improvements in thermal compensation and rigidity over the older GT series
Limitations
- No Y-axis capability limits milling to C-axis interpolation only — off-center features require the SY variant
- 3,500 RPM spindle speed ceiling won't keep up with high-speed aluminum work
- 4,950 kg machine weight needs solid floor prep and limits relocation flexibility
- Live tooling adds cost and complexity over a straight 2-axis turning center

Frequently Asked Questions
01
The LM is the long-bed version with 1,100 mm of Z-axis travel versus 680 mm on the standard M. If you're turning parts longer than about 600 mm, you need the LM. The spindle, turret, and live tooling specs are identical between the two.
02
Yes, it has C-axis capability and live tooling spinning at 6,000 RPM. You can drill, tap, and mill flats using C-axis interpolation. However, it doesn't have a Y-axis, so off-center milling is limited to what you can achieve with C-axis positioning alone.
03
Expect to pay $120,000-$160,000 new depending on options like bar feeder, chip conveyor, and tool presetter. The long-bed and live tooling add a premium over the base DNT 2600. Used examples from the predecessor GT 2600 LM series run $50,000-$80,000.
04
The machine accepts 10-inch or 12-inch chucks (254-305 mm). The 10-inch chuck runs at higher spindle speeds, while the 12-inch accommodates larger workpiece diameters with more clamping force. Your distributor can configure either option.
05
The DNT 2600 LM has more spindle torque (735 Nm vs the Haas's lower output) and longer Z-axis travel. The Haas ST-30Y adds Y-axis milling capability the DNT 2600 LM lacks. For pure turning power with C-axis milling on longer parts, the DN Solutions wins. For full mill-turn versatility, consider the Haas or step up to a DNT 2600 SY.
