Thirty years ago, Doosan Infracore (originally Daewoo) opened its doors in North America for the distribution, sales and service of a family of powerful, high horsepower machine tools, known then and now as Puma turning centers. In its first year, the company offered the DSN20, a 2-axis NC lathe with a top-of-the-line Fanuc 6T controller. Features included a powerful 20 HP, 2,000 RPM spindle drive, quick change aloris tool posts and rapid traverses that topped out at 400 IPM. Much has changed during the past three decades. The name changed in 2005 from Daewoo to Doosan Infracore. The line of machines grew from a single NC lathe to now more than 60 horizontal turning centers and millturns, 35 vertical and horizontal machining centers, plus boring mills and vertical turning centers.And the sales/ service network now numbers more than 50 distributors located throughout North, Central and South America, while Doosan itself has become one of theWesternHemisphere’s three largest machine tool suppliers. “But while Doosan and its family of machine tools have changed, what hasn’t changed is the company’s commitment to machine power,” said a Doosan spokesperson. “Each Doosan machine is designed to do in a single pass what other machines of comparable size often do in three passes or more. And features like integral boxways and torque tube construction, distinguishing characteristics of the company’s early machines in North America, are still featured in many of its machines today. “As part of its 30th anniversary celebration, Doosan is offering savings on key turning centers and machining centers, plus a gift box containing instruments of importance and convenience to people in the metalworking industry. To further help customers gear up in our expanding economy, the company’s financial group is offering special, low interest rates and convenient payment terms. This offering is expected to remain in effect throughout the year.” Looking ahead, Doosan invites members of themetalworking industry to explore advanced productivity options at its booth.
