The Doosan Puma MX mill-turn machines can now be equipped with Coromant Capto machine-adapted clamping units designed for the lower turret for faster and safer tool changes with more tooling rigidity, the company says.
The tool selection consists of OD, ID and face clamping units for static tools. Driven tools for OD and face milling and drilling are available. Double Coromant Capto clamping units are also available to address the subspindle as well as the main spindle. According to the manufacturer, these machine-adapted clamping units provide better performance and faster tool changes. The units are ready-equipped to channel high pressure coolant (80 bar or 1,160 psi) to the cutting heads.
Puma MX models combine milling capabilities with a Doosan turning center.
Depending on the model selected, the turning spindle is powered by motors ranging from 20 to 40 hp and capable of heavy and interrupted cuts in hard materials, long-term accuracy and superior finishes, the company says. The machines are equipped with 12-station turning turrets able to accommodate live tooling at any station and a 40-tool Coromant Capto C6 ATC (80-tool ATC also available). Milling spindles are 25 and 30 hp, depending on the model, with maximum speeds of 12,000 rpm.
