1. The spindle is equipped with an air curtain anti chip device as standard, which avoids internal pressure and dust backflow caused by spindle rotation, ensuring the service life of the bearings.

2. The spindle adopts a floating cutting device, which avoids the direct impact of the cutting cylinder on the spindle bearing during cutting, thereby ensuring the service life of the bearing. 3. The three-axis adopts the H-grade ball track from the famous Japanese manufacturer THK, with HSR35 model for X and Y axes and HSR45 model for Z axis (V-8L or above models), making the entire motion system fast, sensitive, and without crawling phenomenon. The Z-axis track eliminates the gap problem that exists when using the same type of hard rail machine tool as much as possible, making the spindle box have no obvious jumping when changing up and down movements, and reducing tool lines during flat machining.
4. Jiugong spares no expense and uses C3 grade BNFN double nut external circulation ball screws from the renowned Japanese manufacturer THK for all three axes, greatly improving the positioning accuracy and repeatability of the machine tool. This enhances the excellent characteristics of the entire motion pair, such as low friction, low wear, low hysteresis, high speed, high dynamic characteristics, and high lifespan. The machine tool's accuracy retention and dynamic load are greatly improved.
5. The machine tool adopts a high torque spindle motor and spindle unit, combined with a long-lasting high-strength bed body, to meet the requirements of general batch processing to precision part processing.
