**I. Main Structural Features of the Machine Tool:**

1. This machine tool is a CNC machine characterized by high speed, high precision, and high reliability.

The main components such as the bed, base, and headstock are cast from high-strength materials to ensure the stability of the machine over long-term use.

2. The machine tool has high positioning accuracy, smooth chip removal, making it suitable for high-speed and high-precision machining.

3. It features a high-speed, high-precision, and high-rigidity spindle with a variable frequency spindle motor, allowing for higher spindle speeds.

The spindle unit is assembled in a constant temperature environment and undergoes continuous running for 72 hours at a constant temperature

before mounting on the machine. It is then trial-run for another 72 hours to ensure reliable high-speed and high-precision performance.

4. The machine is equipped with an electric tool holder.

5. The X and Z-axis feeds utilize precision ball screws, with the servo motor connected directly to the screw via a high-torque, low-inertia imported

elastic coupling. It features an advanced centralized automatic lubrication system that provides timed and quantified intermittent lubrication,

ensuring stable and reliable operation.

6. The machine's protection features an all-encompassing design that is user-friendly, aesthetically unique, waterproof, chip-resistant, and easy to maintain.
