Turning Center features 20 hp, high-torque motor

Turning Center, torque motor, Lynx,

Today's turning centers can be economical without sacrificing power or precision. Demonstrating this is the Lynx 300, a new turning center from Doosan that's just now entering the United States.

The Lynx's 20 Hp, high torque motor provides the power for heavy cuts and the speed to produce near-mirror finishes. Its 10" diameter 3-jaw power chuck turns 3" bar stock at speeds up to 3,500 rpm, and its recommended price is well below others that do less and cost more.

The Lynx's bed is a one-piece Meehanite casting to absorb vibration and help dissipate heat, while its heavy ribbing resists twisting and distortion. A 30° slant bed maintains a minimal and constant distance between tool tip and guideway. This maximizes rigidity while eliminating distortion under heavy loads. The headstock is mounted on the same plane as the tailstock to assure perfect alignment and center height regardless of the bed temperature. Widely-spaced linear motion guideways allow high-speed rapid traverses - 945 IPM on the X-axis, and 1,181 on the Z.

Each axis is driven by a large diameter, high precision ball screw that is selected for its outstanding combination of accuracy, rapid traverse speeds, and high feed thrust. The ball screws are mounted directly to the A.C. servo motors. This design minimizes backlash for superior machining accuracy. Ball screws on each axis are protected in case of a crash by an electric torque limiter. Upon impact, the torque limiter senses the load and immediately reverses the servo motor and stops the axis movement.

Lynx's 12-station turret features an 8.26" diam. curvic coupling and 11,465 lbs of hydraulic clamp force. This configuration provides high rigidity for superior accuracy and surface finish, long boring bar overhang ratios, and extended tool life. Indexing repeatability is +/-0.0005°. Turret indexing is non-stop and bi-directional, with 0.15 sec. next-station index time. A rotary encoder determines the turret position, and a proximity switch confirms the clamp.

Additional standard features of importance include a waylube separation system, a tool setter that eliminates skim cuts and manually entering tool offsets, automatic forced lubrication, coolant system with a 42 gal. coolant tank, and a part catcher. The controller is a Fanuc 0iTD.

Visitors to IMTS 2010 are invited to see the Lynx 300 in operation at Doosan's front-row booth number S-8100.
