Puma 2600SY from Doosan is a versatile turning center that’s able to machine complex geometries in tough materials quickly and to demanding tolerances.

The machine contains an enhanced, structurally stable bed capable of absorbing the low frequency/high amplitude forces of rapid acceleration and deceleration, and the vibrations associated with heavy and interrupted cuts. It also contains an enlarged bed footprint and more than 50-percent larger guideway width.

The attachment areas for the main and subspindles have also been enlarged to as much as 190 percent for the main spindle and 94 percent for the subspindle. In addition, the spindle body has been shortened to minimize vibration, and the bearing diameter enlarged to improve rigidity. The built-in motor and the new spindle designs facilitate higher feeds and speeds, more accurate roundness, long tool life and optimal surface finishes.

A 24-position turret mounts BMT65P live and stationary tools directly to the turret’s periphery. The turret’s 7.5-hp motor turns live tooling at speeds as high as 5,000 rpm. Tool-to-tool indexing time is 0.15 second.

The machine is designed for parts as large as 14.8” diameter and 29.9” long. An elongated-bed version produces parts as long as 50.4”. The spindle is powered by a 35-hp spindle motor generating speeds as high as 4,000 rpm. The Y-axis movement is achieved by linear interpolation and the synchronous movement of X1 and X2 axes. This makes possible a lower machine height for more stability.

The system is said to include easy accessibility to the turret, spindles and other maintenance areas, a coolant tank that can be removed without disengaging the chip conveyor, a series of heat shields and fans to prevent heat transmission to the machining area and automated tool setting and tailstock functions. The controller is Fanuc i series with a 10.4” color TFT LCD monitor.
