DN Solutions Launches New Series of Turning Machines

The Puma DNT Series is equipped with a powerful spindle, a redesigned turret body and live tool drive that provide precise machining and productivity.

DN Solutions introduces the new Puma DNT 2100 and 2600, which will replace the Puma GT 2100 and 2600 models.

According to DN Solutions, the Puma DNT Series is equipped with the most powerful spindle in its class, a redesigned turret body and live tool drive that guarantee powerful and precise machining and productivity. The design of the new machines focuses on convenient operation and easy maintenance.

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 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.

The DNT Series comes in a two-axis and a milling version. Both have a 25 hp (18.6 kW) or 35 hp (26.1 kW) motor that turn the spindle at speeds ranging from 3,500 to 4,500 rpm.

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″-18.1″ (398.8-460 mm) and the maximum turning length is 21.6″-42.4″ (549-1077 mm). The milling versions come with a maximum turning diameter of 12.6″ to 14.7″ (320-373 mm). The maximum turning length is 19.7″-40.5″ (500 mm-1029 mm). The BMT-55 live tooling turret has speed of 6,000 rpm 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.
