Overview
The DN Solutions MYNX 6500/II is a mid-to-large-sized heavy-duty vertical machining center built for shops that need serious rigidity and generous axis travels without stepping up to a double-column machine. With 1,270 x 670 x 625 mm (50 x 26 x 25 in) of travel, the MYNX 6500/II provides a substantial work envelope that handles large mold bases, fixture plates, and structural components that smaller 40-taper VMCs simply cannot reach. The 1,400 x 670 mm (55 x 26 in) table supports 1,300 kg (2,866 lb), giving shops confidence when loading heavy steel workpieces.
The high-torque spindle delivers 286.5 Nm (211 ft-lb) at 6,000 RPM with 15 kW (20 hp) of power through a BIG-PLUS CAT 50 taper—built for aggressive roughing in steel, cast iron, and hard materials where torque trumps speed. The box guideway construction on all axes provides superior vibration damping and rigidity compared to linear-guide machines in this size class, making the MYNX 6500/II a natural choice for heavy cutting in die/mold and general job shop applications. Rapid traverse hits 30 m/min (1,181 ipm) on X/Y and 24 m/min (945 ipm) on Z.
At 9,500 kg (20,944 lb), the MYNX 6500/II is a serious machine that competes directly with the Mazak VCN-700C, Okuma MB-66VA, and Haas VF-6/50. The FANUC 0i-Plus control with DN Solutions' Easy Operation Package keeps programming and operation straightforward. For shops that have outgrown 40-taper VMCs and need the rigidity of box ways with CAT 50 muscle, the MYNX 6500/II delivers exceptional value in the heavy-duty VMC segment.

Strengths & Limitations
Strengths
- Box guideway construction on all axes delivers superior vibration damping and rigidity for heavy-duty steel and cast iron roughing
- CAT 50 spindle with 286.5 Nm of torque handles large-diameter cutters and aggressive material removal rates that overwhelm 40-taper machines
- Generous 1,270 x 670 mm travel envelope accommodates large mold bases and fixture plates without repositioning
- 1,300 kg table load capacity handles heavy steel workpieces and tombstone fixtures with confidence
- Meehanite cast iron construction provides long-term geometric stability and thermal resistance
Limitations
- 6,000 RPM maximum spindle speed limits high-speed aluminum and finishing work—shops needing speed should look at 40-taper alternatives
- Box guideways sacrifice rapid traverse speed (30 m/min) compared to linear-guide machines that hit 48-60 m/min
- 9,500 kg machine weight requires substantial foundation preparation and limits placement flexibility
- Higher price point than 40-taper VMCs with similar travels—the CAT 50 premium is real

Frequently Asked Questions
01
A new DN Solutions MYNX 6500/II typically runs between $150,000 and $220,000 depending on configuration. The base machine with 6,000 RPM spindle and 30-tool ATC starts around $150,000-$170,000. Adding through-spindle coolant, probing, chip conveyor, and 4th axis prep pushes pricing to $180,000-$200,000. A fully loaded machine with 60-tool ATC and high-pressure coolant reaches $200,000-$220,000. Used MYNX 6500 machines (branded Doosan) typically sell for $80,000-$130,000.
02
The MYNX 6500/II is the current-generation model with updated thermal compensation, improved castings, and the latest FANUC 0i-Plus control. The '/50' designation refers to the CAT 50 spindle taper. Both names refer to essentially the same platform—the II designation indicates the second-generation design with refinements to rigidity, accuracy, and operator interface.
03
Both are CAT 50 VMCs with similar travel envelopes. The MYNX 6500/II has box guideways versus the Haas VF-6/50's inline direct-drive system, giving the DN Solutions machine an edge in heavy cutting rigidity and vibration damping. The Haas typically costs $20,000-$30,000 less and benefits from Haas's extensive service network. The MYNX 6500/II is generally considered the better machine for aggressive steel roughing, while the Haas wins on value and service accessibility.
04
Yes. The MYNX 6500/II offers optional 4th axis preparation with wiring, interface, and control software. The 1,300 kg table load capacity easily handles a rotary table plus workpiece. Most shops pair it with a Tsudakoma or Nikken rotary in the 250-320 mm range. The FANUC 0i-Plus control supports 4th axis programming natively.
