During machining, pneumatic and hydraulic chucks often experience dimensional instability.
These failures are generally preventable if proper countermeasures are taken.
These failures may be caused by insufficient air pressure or a ruptured air line.
Even if the pneumatic or hydraulic chuck is properly installed and properly lubricated during rotation,
if the lathe is subjected to heavy loads, the load will recur even when the lathe is stationary. Over time,
the lathe spindle will fatigue and reach the end of its lifespan. This phenomenon is called fatigue spalling.
We define fatigue spalling as the lifespan of the lathe spindle. In summary, lathe spindle damage can be categorized and classified as follows:
Fatigue spalling = lifespan, wear, increased vibration, increased friction torque, seizure, indentation, rust, and corrosion.
Therefore, the accuracy and life concept of pneumatic chucks and hydraulic chucks, the accuracy of the chuck also comes from the spindle of the lathe.
At the same time, the life can be quantitatively calculated, which is often used when discussing issues such as the durability and precision capability of the chuck.
