Do more with more

Both are flexible machines and can be employed in a number of ways: twin turret capability allows simultaneous OD and ID cutting to occur on a part located in the machine’s main spindle; simultaneous milling and turning of components in the machine’s main and sub-spindle enables multiple finished parts to be completed in one cycle; and operations can be combined by machining one side of a part using the main spindle and then finishing it via the sub-spindle.

“Doosan TT machines have a well-deserved reputation in the market (especially in the aerospace, medical and automotive sectors) for their accuracy, speed and reliability,” says Mills CNC’s technical director, Tony Dale.

“The new machines, with their dual Y-axis capability, build on this strong legacy and take these strengths, along with productivity and efficiency, to a whole new dimension.”

In addition to having Y-axis capability on their upper and lower turrets, the new models also feature LM roller-type guides on the machine’s axes to deliver increased rigidity for improved accuracies and finishes, and greater process reliability.

Up to 40m/minute rapid rates reduce non-cutting times, improve part cycle times and raise productivity levels. Powerful high-accuracy, high-torque main spindles – TT1300SYY spindle capability is 11kW/6,000rpm with 93Nm; TT2100SYY spindle capability is 15kW/6,000rpm with 116Nm – contribute significantly to these levels of performance.

Completing the high specification are high capability 11kW/6,000rpm sub-spindles on both models, low friction ball screw design which mitigates the effects of thermal drift ensuring part accuracies, process security and improved tool life, and 3.7kW/6,000rpm upper turret driven tooling capability on both models.

In addition both machine models feature the Doosan Easy Operation Package for fast and error-free programming and a high performance grease lubrication system that reduces maintenance costs and is more environmentally friendly than traditional oil-based lubrication systems.

Tony Dale concludes: “The new TT machines certainly pack a punch and can operate like self-contained automated manufacturing cells. Component manufacturers looking to improve their productivity will be hard pressed finding anything that can compete with their flexibility, speed and performance.”
