DST240-SY Dual-Spindle 

Turning-Milling Center

Product Description:

DST240-SY dual-spindle dual-turret turning-milling center employs an integrated slant bed base with inclined guideways, featuring dual motorized spindles, dual C-axes, and single Y-axis dual turrets for synchronous dual-spindle/dual-turret machining. Equipped with a hollow hydraulic rotary cylinder and hollow hydraulic three-jaw chuck, it utilizes a new-generation CNC system to execute complex turning and milling operations in minimal setups.

Features:

1.45° integral slant bed base structure ensures excellent stability and vibration resistance.

2.Main and sub-spindles utilize high-torque permanent magnet synchronous motor spindles, delivering high speed, robust rigidity, stable precision, and rapid dynamic response.

3.Servo-driven sub-spindle enables high-speed workpiece transfer, combined with a 12-station interpolated Y-axis servo turret, achieving full or partial machining in one setup to reduce cycle time and boost productivity.

4.Dual C-axis functionality with high-resolution encoders supports workpiece indexing and surface interpolation on either spindle.

5.Pre-stretched nut structures and angular contact bearings on feed-axis ball screws enhance stiffness, thermal resistance, and feed accuracy.

6.Direct servo motor-to-ball screw coupling on feed axes guarantees high transmission precision.

7.High-load linear ball guideways ensure good rigidity, low damping, high precision, and smooth operation.

8.Orthogonal Y-axis and longitudinal and transverse milling support single-setup composite machining (turning, milling, drilling, tapping) on cylindrical/end surfaces, ensuring part accuracy.

9.Left-upper turret features an orthogonal Y-axis and 12-station powered servo turret, while the right-lower turret uses a 12-station powered servo turret, both offering high positioning accuracy, rigidity, and rapid tool indexing.

10.In addition to program control, the hydraulic chuck clamping/unclamping and sub-spindle movement can also be operated through a foot pedal switch, ensuring convenient and efficient operation.

11.Centralized automatic oil lubrication with quantitative distributors ensures uniform lubrication of guides and ball screws, reducing friction, improving motion accuracy, and extending component lifespan.

12.Side and rear chip removal options provide flexible configuration for optimal machining efficiency.

Applications:

Applicable to industries such as automotive, electric, mold manufacturing, telecommunications, instrumentation.
