USED DOOSAN MYNX 6500/50II – 2022

The DOOSAN MYNX 6500/50II – 2022 is a heavy-duty CNC vertical machining center designed for demanding milling, drilling, boring, and tapping applications. The MYNX series is built around a rigid machine structure, large worktable, and powerful 50-taper spindle, making it suitable for machining larger and heavier components than many standard 40-taper vertical machining centers.

The MYNX 6500/50II provides 50″ of X-axis travel, 26.4″ of Y-axis travel, and 24.6″ of Z-axis travel, giving it a substantial machining envelope for large fixtures, castings, housings, plates, and production components. The machine features a 1,400 x 670 mm table with a maximum table load of approximately 1,300 kg / 2,866 lbs.

Its ISO 50 spindle configuration is designed for heavy-duty cutting, with a standard spindle speed of 6,000 RPM. Depending on the machine’s original configuration, spindle motor power and torque can vary. The MYNX 6500/50II platform was offered with multiple spindle configurations, so the exact equipment on an individual 2022 machine should always be verified.

The DOOSAN MYNX 6500/50II – 2022 is well suited for manufacturers in aerospace, automotive, energy, oil and gas, heavy equipment, mold and die, industrial machinery, and general contract machining.

WHY CHOOSE DOOSAN MYNX 6500/50II

The DOOSAN MYNX 6500/50II is designed for manufacturers that need the rigidity and tooling capacity of a 50-taper vertical machining center. Its 50″ X-axis travel, 26.4″ Y-axis travel, and 24.6″ Z-axis travel provide a substantial machining envelope, while the 1,300 kg table capacity allows larger and heavier workpieces to be machined efficiently.

The 50-taper spindle system provides a more robust platform for heavy milling, large-diameter tooling, deep cuts, and demanding materials. Depending on the spindle configuration, buyers may also find machines equipped with higher-power and higher-torque spindle options.

For shops producing large components or requiring aggressive metal removal, the MYNX 6500/50II can offer a useful combination of machining capacity, spindle rigidity, and production flexibility.

WHY BUY USED DOOSAN MYNX 6500/50II – 2022

A used 2022 DOOSAN MYNX 6500/50II can provide relatively modern heavy-duty machining capability at a lower investment than purchasing a comparable new 50-taper machining center.

When evaluating a used machine, inspect the spindle, spindle bearings, X/Y/Z-axis ballscrews, guideways, servo motors, automatic tool changer, coolant system, lubrication system, CNC control, electrical cabinet, and machine enclosure.

Buyers should verify spindle runout, spindle noise, axis positioning accuracy, backlash, rapid traverse operation, tool-change reliability, coolant performance, and overall machine geometry.

Because MYNX machines can be supplied with different spindle, control, coolant, tool magazine, and automation configurations, the individual machine’s option list should be reviewed carefully. A machine equipped with high-torque spindle options, through-spindle coolant, chip conveyor, probing, additional tool capacity, or rotary tables may command a higher resale value.
