High-precision screw plays a vital role in CNC machining centers. It is one of the key components to achieve positioning and motion control of CNC machining centers. The following is about the role and characteristics of high-precision screws in CNC machining centers:

1. Positioning accuracy: The high-precision screw has very high positioning accuracy and can achieve micron-level or even higher level positioning accuracy. This is crucial for workpieces that require precision machining, ensuring the quality and accuracy of the machining results.

2. Smoothness of movement: The manufacturing process and material selection of the high-precision screw ensure its smoothness of movement, and it can maintain a stable movement trajectory even in the case of high-speed movement and frequent reciprocating movements.

3. Wear resistance and durability: The high-precision screw rod of CNC machining center is usually made of high-strength, high-wear-resistant materials, which can maintain stable performance for a long time, reduce errors caused by wear, and extend service life.

4. Low friction and high efficiency: The surface of high-precision screw rods is usually specially treated to have a lower friction coefficient, thereby reducing energy loss and improving transmission efficiency, allowing CNC machining centers to operate more energy-saving and efficient.

5. Low noise: The high-precision screw moves smoothly and has low friction, so the noise generated is relatively low, which is beneficial to improving the comfort of the working environment.

6. Automatic compensation function: Some advanced CNC machining centers are equipped with an automatic compensation function, which can monitor the wear and deformation of the screw in real time and compensate through system adjustments to maintain high-precision processing results.

7. Wide applicability: High-precision screws are suitable for various types of CNC machining centers, including milling machines, lathes, drilling machines, etc., and can meet the needs of different processing workpieces.

In general, high-precision screws play a vital role in CNC machining centers, directly affecting processing accuracy, efficiency and stability. They are one of the keys to the high performance and high precision of CNC machining centers.
