Upgraded Turning Center Series Drives Precise Machining, High Productivity

DN Solutions introduces the new Puma DNT 2100 and 2600. The DNT Series will replace the popular Puma GT 2100 and 2600 models, with upgrades in enhanced rigidity, usability and accuracy, and a focus on convenient operation and easy maintenance. This DNT Series comes in a two-axis and a milling version, with a 25 hp (18.6 kW) or 35 hp (26.1 kW) motor that turn the machine’s spindle at speeds ranging from 3,500 to 4,500 r/min.

Like the GT Series, box guideways are applied to all axes on the DNT Series to prevent vibration and ensure dynamic rigidity during heavy-duty cutting. Rigidity enhancements 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 that guarantee precise machining and exceptional productivity, the company says.

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 is said to improve on machining accuracy by optimizing the spindle structure and adopting the thermal compensation function (optional). A low heat generation bearing in the new live tool drive also help to minimize thermal deformation. Chuck sizes are also common to both configurations with a range of 8-12" in diameter.

The maximum turning diameter of the two-axis models is 15.7" (398.8 mm) to 18.1" (460 mm) and the maximum turning length is 21.6" (549 mm) to 42.4" (1,077 mm). The milling versions come with a maximum turning diameter of 12.6" (320 mm) to 14.7" (373 mm). The maximum turning length is 19.7" (500 mm) to 40.5" (1,029 mm). The BMT-55 live tooling turret has speed of 6,000 r/min powered by a 7.5 hp (5.6 kW) motor.
