product description
-
1. Integrated Body with Whole Metal Cover
The CNC machine features a robust monolithic cast iron body integrated with a full-enclosure metal cover, ensuring exceptional structural rigidity and vibration damping. This design enhances machining stability and precision while providing comprehensive protection against coolant splashes, metal chips, and external contaminants. The seamless enclosure also improves operator safety by minimizing exposure to moving components.
-
2. Servo Spindle with Hydraulic Clamping System and Tailstock
Equipped with a high-torque servo-driven spindle (typically 7.5–15 kW), the machine delivers variable-speed performance (e.g., 50–4,500 RPM) for versatile material processing. The hydraulic clamping system ensures rapid and secure workpiece fixation, reducing setup time and improving repeatability. A programmable CNC tailstock (optional hydraulic or pneumatic actuation) provides axial support for long shafts or complex parts, enabling balanced machining of slender components with micron-level accuracy.
-
3. 8 or 12 Station Tool Turret
A motorized indexing tool turret (8 or 12 stations) allows automatic tool changes in ≤0.3 seconds, optimizing productivity for multi-operation workflows. Each station accommodates standard ISO/BT-40 tool holders, supporting drills, end mills, turning tools, and custom attachments. The turret’s servo-driven positioning system achieves ±0.001° angular accuracy, ensuring seamless transitions between roughing, finishing, and threading operations.
-
4. Optional Chip Conveyor
A hinged belt-type chip conveyor (optional) efficiently removes swarf and debris from the machining area, reducing downtime for manual cleaning. With a capacity of 80–120 kg/min, it supports continuous operation in high-volume production environments. The conveyor’s modular design allows integration with centralized coolant filtration systems, promoting workplace cleanliness and coolant recycling.
-
5. Slant Bed with Screw Lead and Linear Guide Rail
The 30°–45° slant bed configuration optimizes chip evacuation and provides superior rigidity compared to flat-bed designs. Paired with ground ball screws (C3/C5 accuracy grade) and preloaded linear guideways (HIWIN or equivalent), the machine achieves rapid traverse speeds up to 24 m/min and positioning repeatability of ±0.003 mm. This combination minimizes thermal deformation and ensures consistent performance during heavy-duty cutting or high-speed finishing.

6. GSK980Tb3i Bus System
The GSK980Tb3i CNC system utilizes a high-speed fieldbus architecture for real-time communication between the controller, drives, and peripherals. Key features include:
- 10.4" color LCD touchscreen with intuitive graphical programming interface
- Support for ISO code, parametric cycles, and custom macro-B programming
- Integrated PLC for I/O control (up to 256 points) and auxiliary device synchronization
- Adaptive feedrate control and backlash compensation for error-free contouring
- USB/RS-485 connectivity for data transfer and remote diagnostics
