New Turning Center Series Sets New Standards

Nov. 10, 2022
The new PUMA DNT machines have a powerful spindle, a redesigned turret body, and live tool drive – in a design that focuses on convenient operation and easy maintenance.

DN SOLUTIONS introduced the PUMA DNT 2100 and 2600 turning centers (replacing the PUMA GT 2100 and 2600 models) and featuring “the most powerful spindle in its class,” a redesigned turret body, and live tool drive that promote powerful, precise machining and outstanding productivity.

The design of the new machines focuses on convenient operation and easy maintenance, according to DN Solutions (formerly Doosan Machine Tools.)

“The GT Series has been an international best-seller for a long time,” according to Andy McNamara, vice president of Sales and Marketing at DN Solutions America. “But we never stop looking for ways to upgrade our products and improve the machining experience of our customers.”

The upgrades to the DNT Series include features that separate it from the GT predecessors by way of enhanced rigidity, usability, and accuracy. Like the GT Series, box guideways are applied to all axes on the DNT Series to prevent vibration, ensure dynamic rigidity, and deliver powerful and precise machining during heavy-duty cutting.

Rigidity enhancements on the DNT Series consist of an improved bed design, which includes increased guideway span and saddle width, a higher rigidity bearing arrangement in the main spindle, and adoption of a high rigidity, low temperature live tool drive.

Convenience features on the DNT Series include an ergonomic control panel with adjustable height iHMI touch screen for quick and easy operation, a wider maintenance space and the addition of an inverter type chip converter with a 45° incline cover design for better chip handling.

The PUMA DNT Series improves machining accuracy by optimizing the spindle structure and adopting the (optional) thermal compensation function. A low heat generation bearing in the new, live tool drive also help to minimize thermal deformation.

The DNT Series comes in a two-axis and a milling version: each has a 25 hp (18.6 kW) or 35 hp (26.1 kW) motor that turns the spindle at speeds ranging from 3,500 to 4,500 r/min.

Chuck sizes are also common to both configurations with a range of eight to 12 inches in diameter.

The maximum turning diameter of the two-axis models is 15.7 in. (398.8 mm) to 18.1 in. (460 mm) and the maximum turning length is 21.6 in. (549 mm) to 42.4 in. (1077 mm).

The milling versions come with a maximum turning diameter of 12.6 in. (320 mm) to 14.7 in. (373 mm). The maximum turning length is 19.7 in. (500 mm) to 40.5 in. (1029 mm).

The BMT-55 live tooling turret has speed of 6,000 r/min powered by a 7.5 hp (5.6 kW) motor.

Options that add to the versatility of the DNT Series include a high-torque spindle, servo tailstock, servo automatic door, and others. For light automation, a parts conveyor and various bar feeders are offered.

“The PUMA DNT Series machines have the largest machining areas in their class and deliver maximum productivity with minimum cost,” McNamara said. “You won’t find a more comprehensive range or a better combination of value, performance and reliability anywhere else.”
