1.Direct drive synchronous electric spindle device: Magnetic ringtypeincremental encoder (Sine and cosine) positioning accuracy: 20 arc seconds, C-axis indexing accuracy: 40 arc seconds.
Effectively eliminates spindle vibration.spindle,with nose end deflection accuracy within 0.002mm.Improves the surface finish of workpieces.
Rear-mounted rotor design facilitates installation and maintenance.
The spindle motor is equipped with a cooling system to mitigate thermal displacement, ensuring a constant spindle working temperature. This spindle system has passed rigorous dynamic balance tests, ensuring precision retention, high rigidity, and efficiency. This allows the machine to handle both finishing and rough machining tasks, even heavy cutting. Ideal for mass production of complex shapes with high finish requirements.products.
2. High rigidity integral servo power turret. The Y-axis, with a 100MM stroke (±50 from the center line), supports eccentric milling, drilling, and tapping. Equipped with a high-torque power turret and a servo-driven C-axis, it can process complex parts. The tool holder installation features a high-rigidity BMT interface, and the power transmission shaft is driven by a servo spindle motor.
3. The machine is equipped with THK linear guide rails and ball screws. The heat-treated, precision-ground ball screws ensure optimum precision and durability. Each axis employs a direct transfer shaft structure and a double-anchor pre-relay method to minimize thermal displacement and significantly enhance machining accuracy. High rigidity, large size, and heavy-duty linear slide rails maintain machine accuracy under impact, with smooth displacement and low noise, extending service life.
4. Standard configuration includes a FANUC system, with the feed drive powered by a FANUC servo motor.
5. Perfect hydraulic and lubrication system features high-quality hydraulic pumps, valves, and components, greatly reducing failure rates. The system design is simple and reliable.
6. The high-rigidity structure and integral hydraulic tailstock eliminate vibration and provide excellent stability. The sleeve's telescoping operation via a hydraulic cylinder is convenient and reliable.
7. Features a Taiwan rotary chuck, oil cylinder, and automatic chip removal device, significantly reducing operator labor intensity and ensuring safe, efficient production. These components can be controlled via programming. Additionally, various special fixtures can be designed and installed according to user requirements.
