### What is a pneumatic chuck?

A pneumatic chuck is a type of chuck that uses compressed air to clamp and hold workpieces securely in place during machining operations. It is commonly used in CNC machining, turning, milling, and drilling processes to improve efficiency and precision.

### How does a pneumatic chuck work?

1. **Air supply**: The pneumatic chuck is connected to an air supply through a hose or tubing. When the air supply is turned on, compressed air flows into the chuck to activate its clamping mechanism.

2. **Clamping mechanism**: Inside the pneumatic chuck, there are pneumatic cylinders or pistons that move to apply pressure and clamp the workpiece securely. The pressure exerted can be controlled and adjusted according to the requirements of the application.

3. **Jaws**: Pneumatic chucks often have jaws that can move independently to accommodate different sizes and shapes of workpieces. These jaws can be adjusted manually or automatically, depending on the design of the chuck.

4. **Release mechanism**: To release the workpiece, the air supply is turned off, allowing the pressure to be relieved and the jaws to open. This makes it easy to remove the finished part and load a new workpiece quickly.

In summary, a pneumatic chuck works by using compressed air to activate a clamping mechanism that securely holds workpieces in place during machining operations. Its adjustable jaws and quick release mechanism make it a versatile and efficient tool for various industrial applications in 2021.
