Overview

The DN Solutions SMX 2600 is a multi-tasking mill-turn machine that brings full B-axis milling capability to a 10-inch chuck platform. Formerly the Doosan PUMA SMX 2600, this machine sits in the sweet spot of the SMX lineup — large enough for serious production work but more compact and affordable than the SMX 3100 series. It competes directly with the Mazak Integrex i-200, DMG Mori CTX beta 800, and Okuma Multus B250II.

The main spindle delivers 26 kW (35 hp) at 3,500 RPM through a 10-inch chuck, with 850 Nm (627 ft-lbs) of torque for strong turning performance on steel and stainless. The B-axis milling spindle hits 12,000 RPM with 22 kW (30 hp) and Capto C6 taper, swinging through 240 degrees (+/- 120 degrees) for full angular milling access. This gives you genuine machining center capability integrated into a turning platform.

Axis travels span 615 mm on X, 300 mm (+/- 150 mm) on Y, and 1,050 mm on Z, with 540 mm (21.3 in) max turning diameter and 1,050 mm (41.3 in) max turning length. The 60-tool ATC (expandable to 80 or 120) with fast tool-to-tool changes keeps complex multi-operation parts cycling efficiently. Bar capacity of 80 mm (3.1 in) through the main spindle supports bar feeder automation.

The machine runs on a FANUC 31i-B5 control with CUFOS 5-axis simultaneous capability. At roughly 14,000 kg (30,865 lb), it's more manageable to install than the larger SMX 3100 variants. New machines price between $280,000 and $400,000, making it one of the most accessible entry points into B-axis multi-tasking. For shops that don't need the 12-inch chuck and extended turning length of the SMX 3100, the 2600 delivers the same done-in-one philosophy in a smaller, more affordable package.

Strengths & Limitations

Strengths

240-degree B-axis milling spindle at 12,000 RPM with Capto C6 taper provides genuine machining center capability for angular milling, drilling, and tapping on a turning platform
10-inch chuck with 26 kW spindle and 850 Nm torque handles a wide range of part sizes without the larger footprint and cost of the SMX 3100 series
60-tool ATC (expandable to 120) supports complex multi-operation parts with enough tool positions for roughing, finishing, drilling, and tapping in a single setup
Significantly lower price than comparable Mazak Integrex, DMG Mori CTX, and Okuma Multus machines — roughly 25-30% less for similar B-axis multi-tasking capability
80 mm bar capacity through the main spindle supports bar feeder automation for unattended production of medium-diameter parts

Limitations

3,500 RPM main spindle is slower than the 5,000 RPM offered by Mazak Integrex i-200 and Okuma Multus B250II, limiting high-speed small-diameter turning
Single-spindle configuration means parts requiring back-working need manual rechucking or stepping up to the SMX 2600S or 2600ST with sub spindle
Roller linear guideway construction trades some rigidity for speed compared to box-way competitors, noticeable under heavy interrupted cutting loads
B-axis accuracy can require custom macro compensation to hold tolerances under 0.01 mm, as documented by users of the SMX platform

Best For

Job shops entering multi-tasking without the $400K-$600K price tag of Japanese and European competitors, where the compact SMX 2600 provides done-in-one capability at an accessible price Aerospace and defense shops machining medium-sized components with complex OD/ID features, cross-holes, and angular milling that benefit from single-setup processing Oil and gas manufacturers producing valve bodies, connectors, and fittings up to 540 mm diameter with multiple machined features Shops already standardized on FANUC controls adding multi-tasking capability without retraining on Mazatrol, OSP, or Siemens platforms

Frequently Asked Questions

01 What does a new DN Solutions SMX 2600 cost?

New SMX 2600 machines typically price between $280,000 and $400,000 depending on configuration and options. Base machines with 60-tool ATC start around $280K, while fully loaded configs with high-pressure coolant, probing, and expanded tool magazine push toward $400K. The S variant (with sub spindle) adds roughly $40-60K, and the ST variant (sub spindle plus lower turret) adds $80-120K over the base price.

02 What's the difference between the SMX 2600 and SMX 3100?

The SMX 2600 uses a 10-inch chuck with 540 mm max turning diameter and 1,050 mm turning length, while the SMX 3100 steps up to a 12-inch chuck with 660 mm turning diameter and 1,540 mm turning length. The 3100 also has a more powerful 30 kW main spindle vs 26 kW on the 2600. Choose the 2600 for medium-sized parts where the smaller footprint and lower price are advantages; choose the 3100 when you need the larger work envelope.

03 Can the SMX 2600 do full 5-axis simultaneous machining?

Yes. The FANUC 31i-B5 control with CUFOS provides full 5-axis simultaneous capability using the B-axis milling spindle, C-axis (spindle rotation), X, Y, and Z linear axes. This enables complex contouring operations on turbine blades, impellers, and other freeform surfaces directly on the multi-tasking platform.

04 Is the SMX 2600 available with a sub spindle?

Yes. The SMX 2600S adds a sub spindle for back-working capability, and the SMX 2600ST adds both a sub spindle and a lower turret with live tooling for simultaneous operations. The base SMX 2600 is single-spindle only, so parts requiring back-working need manual rechucking unless you step up to the S or ST variants.
