2020 Doosan PUMA MX2100ST B-Axis CNC Mill-Turn Machine with Sub-Spindle & Bar Feeder

The Doosan PUMA MX2100ST is a multi-tasking mill-turn machine with a reputation for dependable done-in-one production that has made it a staple in job shops and contract manufacturers running complex turned and milled parts. This 2020 unit is a B-axis CNC mill-turn center that combines an upper B-axis milling spindle, a lower turret with live tooling and C-axis capability, and a sub-spindle that takes the part for back-side operations, so turning, milling, drilling, tapping and contouring can be completed without moving the part to a second machine. The main spindle is set up with a collet chuck for bar work, and the sub-spindle carries a 3-jaw chuck. Bar stock is fed by an IEMCA Kid 80+ bar feeder with its own touchscreen pendant, a pairing designed for bar-fed production runs. The machine runs a Fanuc control with a handheld MPG for setup, and it is equipped with a hinged-belt chip conveyor, a swing-arm tool presetter for fast tool offsets, and two chuck foot pedals for operator loading. With its upper milling spindle and lower live-tool turret working the same part, the MX2100ST is built to cut setups and handling on parts that would otherwise travel between a lathe and a machining center.

Compared with earlier Daewoo and Doosan PUMA MX2100ST builds from the late 2000s, this 2020 unit comes from the later production years of the series, giving a buyer a late-production example of the platform rather than a machine more than a decade older. Against conventional Doosan turret lathes such as the PUMA 2100SY and PUMA 2600SY, the MX2100ST adds a dedicated B-axis milling spindle above the turret, so angled holes, contoured features and heavier milling can be handled on the same machine instead of on a separate machining center. For shops moving up from twin-spindle turning centers, that means fewer setups, less work-in-process, better feature-to-feature relationships from machining in one clamping, and more spindle time spent cutting rather than waiting on a second operation. The result is a meaningfully more capable machine, not just a newer one.
