The gas source of the numerical control machine tool pneumatic device is easy to obtain, and the numerical control machine tool can eliminate the need to separately distribute the power source. The device structure is simple, the working medium does not pollute the environment, the working speed is fast, the action frequency is high, and it is suitable for the auxiliary work of frequent starting. It is also safer when overloaded, and it is not easy to cause accidents such as overload damage to the machine. It is widely used in the automatic clamping and loosening of the tool in the spindle of CNC machine tools, the cleaning of the spindle taper chip, the unloading of the tool magazine, the automatic switch of the machine protection door, and the automatic drafting and cleaning positioning reference surface of the exchange table. .

When installing and debugging the pneumatic system of CNC machine tools, please pay attention to:

1. The components should be cleaned before installation and sealed if necessary.
2. The direction or mark of the arrow on each type of valve body should conform to the direction of airflow.
3. Do not install the dynamic seal ring too tightly, especially the U-shaped seal ring, otherwise the resistance is too great.
4. The center line of the moving cylinder should be concentric with the center line of the load force, otherwise it will cause lateral force, which will accelerate the wear of the seal and bend the piston rod.
5, the system pressure should be adjusted properly, generally 0.6MPa.

6. Pneumatic triplex should work normally.
