PRODUCTS PRODUCTS 48 PRODUCTION MACHINING :: APRIL 2018 Turning Center Minimizes Idle Time Doosan Machine Tools America's Puma TW 2600/M-GL is a high-performance, 10" class, two-spindle turning center with an integrated gantry loader. The turning center is the result of input from the automotive industry for a gantry loaded turning center that reduces cycle time for high volume production runs. The machine is an upgrade of the previous model with features that give it a larger working range in addition to upgrades in speed and ease of use, the company says. Idle time has been minimized by reduc- ing the gantry loader handling time during both the loading and unloading cycle. The Y-axis rapid traverse rate is 34 percent faster than the previous model and the gantry loader cycle time is 28 percent shorter. The built-in loader guidance soft- ware also provides gantry loader opera- tion and machine maintenance. The turning center comes standard with a high-power spindle, which generates a maximum 19-kW (25-hp) and 404-Nm (298 foot-pounds) of torque. The spindle length of 513 mm (20") is 6 percent shorter than the previous model to reduce vibration and noise. According to the com- pany, the bearing size of 110 mm (4") is 10 percent bigger than the previous model to enhance spindle rigidity and improve heavy duty machining capability. :: Doosan Machine Tools America 973-618-2500 Leistritz Advanced Technologies Corp. 165 Chestnut Street, Allendale, NJ 07401 • 201 934-8262 • Leistritz has developed internal whirling, a process to cut long internal threads without tilting the tool at helix angle. The method utilizes the bore to support the carbide or CBN cutting tool for extremely accurate profiles and overall geometries. This special purpose machine, model LWN-120-IW, has high frequency oscillation to cut threads with high helix angles and/ or multiple starts.
