Turning Center Features Increased Precision
The Puma 3100 horizontal turning center from Doosan is designed for speed, precision and performance.
A 12-staton turret selects BMT65 tools bi-directionally in 0.15 sec. The turret is non-lifting to eliminate coupling contamination. A 9" curvic coupling with 11,900 lbs of hydraulic clamping force provides rigidity for heavy stock removal, fine surface finishes, long boring bar overhang ratios and extended tool life. Rotating tools are powered by a 7.5-hp motor that generates 34.7 foot-pounds of low-end torque and speeds ranging to 5,000 rpm. A tool setter reduces setup time by minimizing manual skim cuts. Offsets are calculated and automatically entered into the program, virtually eliminating clerical errors, the company says.
