2022 Doosan Mynx 5400/50 II CNC Vertical Machining Center

The Doosan Mynx 5400/50 II is a heavy-duty CNC vertical machining center with a reputation for rigidity and dependable production performance that has made it a staple in job shops and high-mix manufacturing environments. This 2022 unit is built around a 50-taper Big Plus CAT 50 spindle turning up to 6,000 RPM on a 30 HP drive, delivering the low-end torque needed for heavy cuts in steel, stainless, and cast iron. It offers work envelope travels of 40.2 x 21.3 x 20.8 inch (X/Y/Z) over a 47.2 x 21.2 inch table, with rapid traverse rates of 1,181 IPM for fast, efficient cycle times. Tool changes are handled by a 24-station side-mount automatic tool changer, and the machine runs on the current-generation Fanuc 0i-MF Plus control with Doosan EZ Guide conversational programming for quick setups right at the machine. Additional equipment includes an LNS Turbo hinge-belt chip conveyor, a Mist-Fit MF-550 mist collector, a Nanocon oil chiller, an SKF automatic lubrication system, flood coolant, telescopic way covers, and 4th-axis wiring for future rotary expansion.

Compared to the original Doosan Mynx 5400, the Mynx 5400/50 II generation is a meaningful step forward rather than just a newer badge. The II series pairs the machine with the updated Fanuc 0i-MF Plus control - a faster, higher-memory platform than the earlier Fanuc 0i-MC and 0i-MD controls found on first-generation Mynx machines - and adds a CAM-type tool changer engineered for quicker tool-to-tool changes and higher productivity. Doosan also reinforced the structure of the II series for improved stability and accuracy under heavy-duty cutting loads. For a buyer, that means the throughput and control refinements of a current-generation heavy 50-taper VMC in a proven, ready-to-run package - a genuine production upgrade over the earlier Mynx 5400 it replaces.
