HIGH RIGIDITY AND HEAVY CUTTING CAPABILITY
Structural Design: The machine features an integral cast inclined bed paired with 30° inclined guide rails. This design enhances operator accessibility to the workpiece and ensures smooth cutting operations.
HIGH PRECISION AND DYNAMIC RESPONSE
Bearing System: Two pairs of NSK P4 bearings are employed to provide exceptional rigidity and precision. This setup enables the spindle to achieve remarkable rotation accuracy.
Speed Control: The spindle's speed is regulated smoothly via an AC servo motor, ensuring consistent performance across various cutting conditions.
THERMAL STABILITY
Reduced Distortion: Both the main spindle box and the sliding saddle are aligned on the same angular plane. This configuration helps minimize distortion resulting from thermal expansion of the spindle box.
Lubrication and Temperature Management: High-speed rolling bearings and a quantitative grease sealing lubrication system are utilized to maintain thermal stability, ensuring that both the machine body and spindle remain at consistent temperatures.
