HOW MUCH DOES A USED DOOSAN MYNX 6500/50 II COST?
The price of a used 2022 DOOSAN MYNX 6500/50 II depends on several factors including machine condition, spindle hours, control configuration, installed options, tool changer capacity, coolant system, chip conveyor, probing equipment, maintenance history, location, and current used CNC machinery market conditions.
Unlike smaller vertical machining centers, the MYNX 6500/50 II is a large heavy-duty machine, so transportation, rigging, installation, electrical preparation, and commissioning can represent a significant portion of the total acquisition cost.
A typical used 2022 DOOSAN MYNX 6500/50 II may commonly be offered in the approximate $110,000 to $190,000 range depending on configuration, condition, hours, accessories, and seller. Exceptional machines with low operating hours, desirable options, strong maintenance records, and production-ready accessories may be listed outside this range.
Machine condition is one of the most important factors affecting price. Buyers should evaluate the spindle, axis positioning, ballscrews, guideways, tool changer, coolant system, lubrication system, electrical cabinet, control system, and machine geometry before determining whether a particular asking price is reasonable.
The spindle is especially important because the MYNX 6500/50 II is designed for heavy-duty cutting. Buyers should check spindle noise, vibration, temperature behavior, tool retention, taper condition, and overall spindle performance.
Tool changer configuration can also affect pricing. MYNX 6500/50 II machines may be found with different tool-storage configurations, and a machine equipped with a larger tool magazine can provide additional production flexibility. Published specifications identify 24- and 30-tool configurations for the 6500/50 II platform.
Accessories can significantly change the overall value of a used machine. Chip conveyors, probing systems, high-pressure coolant, additional tooling, workholding equipment, and specialized production options may reduce the amount of additional investment required after purchase.
The control system should also be inspected carefully. Buyers should verify that the CNC control boots correctly, accepts programs, communicates with peripheral equipment, operates all axes correctly, and does not display unresolved alarms.
Machine location is another cost consideration. A large MYNX 6500/50 II weighs approximately 9,500 kg, so transportation and professional rigging can be substantial.
Buyers should therefore consider the total acquisition cost, rather than focusing only on the machine’s advertised purchase price. Transportation, rigging, installation, electrical service, coolant, tooling, workholding, inspection, and commissioning can all influence the final investment.
The 2022 model year also makes the machine relatively modern within the used CNC market, which can be attractive to manufacturers seeking newer equipment without paying full new-machine pricing.
For manufacturers requiring a large-format vertical machining center with extensive axis travel, an ISO #50 spindle, substantial worktable, and heavy-duty construction, the used DOOSAN MYNX 6500/50 II represents a substantial production platform.
Its combination of approximately 50-inch X travel, 26.4-inch Y travel, 24.6-inch Z travel, 55.1 × 26.4-inch table, 50-taper spindle, and approximately 2,866-pound workpiece capacity provides a strong foundation for demanding industrial machining applications.
