The Doosan PUMA MX2100ST is a multitasking turn-mill center with a reputation for rigid, dependable construction that has made the PUMA MX line a staple in job shops and production cells machining complex turned-and-milled parts. This 2020 PUMA MX2100ST is a B-axis CNC mill-turn machine built around an upper turn-mill head with a B-axis milling spindle, paired with a lower turret equipped with live tooling. The machine carries Y-axis and C-axis capability for off-center milling, drilling and tapping, and a main spindle with a sub-spindle for complete front-and-back machining, so parts can be transferred and finished without a second operation. This unit is fitted with one 3-jaw chuck and one collet chuck across its two spindles, coolant to the chucks, a tool presetter arm for tool offset setting, a chip conveyor, a three-light stack light, a manual pulse generator handwheel and two chuck foot pedals. Control is a Fanuc Series 31i-Model B5, a five-axis-capable Fanuc CNC widely used on multitasking machines, giving programmers a familiar platform for multi-axis and mill-turn programming. For shops consolidating lathe and machining-center work, the PUMA MX2100ST is designed to reduce setups, cut part handling and shorten lead times on complex components for aerospace, medical, energy, hydraulics and general precision work.
Compared with the earlier Doosan PUMA MX2000ST, the PUMA MX2100ST represents the later generation of Doosan's PUMA MX multitasking platform, and this 2020 build carries the Fanuc 31i-Model B5, a later Fanuc control generation than the 31i-Model A. The 31i-B5 brings a more current Fanuc hardware and software platform for multi-axis turn-mill work, with stronger support for five-axis machining functions and modern program management. Combined with its B-axis turn-mill head, live-tool lower turret and sub-spindle, the PUMA MX2100ST gives buyers a meaningfully more capable mill-turn platform than the older PUMA MX2000ST, translating into faster setups and more complete part processing on the shop floor.
