CNC milling-turning center SD0838

horizontal2-axisdouble-spindle

This compact, high-precision double-spindle CNC turn-mill center is engineered for integrated turning, milling, drilling and tapping in a single clamping, improving throughput and accuracy for medium- to high-precision parts.

Key features

• Compact turn-mill center combining turning, milling, drilling and tapping in one machine.
• Single-clamping machining reduces work handling and improves dimensional repeatability.
• Double-spindle layout (main + sub) for simultaneous or sequential operations and higher productivity.
• Main and sub power turrets (BMT series) for fast tool change and heavy turning/milling cuts.
• Optional automation (gantry/robot/bar feeder/part catcher) for semi-automated or lights-out production.

Machine composition and important components

• Machine body: Horizontal slant bed cast from HT300 for rigidity, vibration damping and long service life; design facilitates full-part loading and chip evacuation.
• CNC system: Standard SYNTEC 22TB (serial comm., 4G memory); optional FANUC or SIEMENS; systems support multi-servo integration and direct spindle positioning.
• Spindles: Built-in direct-drive synchronous electric spindles — main 15 kW (A2-6, Ø66 mm bore), sub 8.5 kW (A2-5, Ø56/Ø48 mm bore options). Spindle bearings: NTN P4 grade.
• Chucks: Hydraulic hollow chucks — main 8" 3-jaw, sub 6" 3-jaw. Matching surfaces hardened and ground; direct lubrication for high rigidity and clamping accuracy.
• Turrets: Main turret BMT45 15-station (Y axis optional), sub-turret BMT55 12-station power turret for heavy-duty cutting.
• Guide ways: PMI roller guide ways (X/Z 35 mm) with multiple slide blocks for high load capacity and stable accuracy.
• Ball screws: PMI C3 grade (X/Z 3210/4012) with oil lubrication and cooling; servo-driven for fast, accurate positioning.
• Hydraulic & lubrication: Seven Ocean hydraulic station (40 L) for spindle cylinder, chuck and tailstock; Ishan oil lubrication system (2L/4L) for guideways and screws; Schneider low-voltage electrical components and safety interlocks.
• Cooling & cleaning: Luikar 2V-30 coolant pump with large tank (120 L) and filtration for coolant circulation.
