Y-Axis Horizontal Turning Center for Tough-to-Machine Materials

For unprecedented rigidity and accuracy, active thermal compensation in the high productivity PUMA 2600 SY II from Doosan Machine decreases deformation up to 70 percent and a built-in spindle minimizes vibration with better acceleration and a smooth, fast ramp-up.

The built-in spindle on the PUMA 2600 SY II sub-spindle Y-axis horizontal turning center from Doosan Machine, generates up to 30 hp and 442.1 ft-lb of torque. A durable 12-station milling turret increases clamping force and BMT tooling delivers unsurpassed rigidity for heavy chip removal, fine surface finishes, long boring bar overhang ratios, and extended tool life.

The high productivity PUMA 2600 SY II sub-spindle Y-axis horizontal turning center from Doosan Machine Tools America (Pine Brook, NJ) can craft high precision parts from a range of tough-to-machine materials. The PUMA 2600 SY II is a 10 in class system with a newly designed bed for unprecedented rigidity and accuracy. Its standard active thermal compensation system decreases the effects thermal deformation by 60 percent to 70 percent over the previous model. NTN sliding bearings have been applied to all axis box guide ways on the carriage, improving fine movement by more than 40 percent and wear resistance by more than 30 percent. The feed box and X-axis bearing mount have been reinforced for high rigidity. Its built-in spindle minimizes vibration and provides better acceleration and a smooth, fast ramp-up that generates a maximum 22 kW (30 hp) and 599 Nm (442.1 ft-lb) of torque.

Improved spindle run out (6 μm) has been achieved by changing the structure of the spindle bearings and making it more suitable to high precision and improved surface finishes. The 12-station milling turret has been redesigned for improved durability and increased clamping force. BMT tooling provides unsurpassed rigidity for heavy chip removal, fine surface finishes, long boring bar overhang ratios, and extended tool life. A FANUC i series operation panel has a new ergonomic design and an updated Easy Operation Package (EOP) with improved setup, operation and maintenance programming.
