In the process of machining, pneumatic chucks and hydraulic chucks often have dimensional instability. If these faults are taken in advance, they can be prevented. It may be that the air pressure is insufficient and the air pipe is broken. Even with pneumatic chucks, the hydraulic chucks are properly installed and lubricated during their rotation. If the lathe is subjected to large load processing, from the outside point of the lathe, even if the load is stopped, the load does reciprocate. The spindle of the lathe has been fatigued for a long time to reach the end of its life. The phenomenon is that this phenomenon is called fatigue spalling. At the same time, we define fatigue spalling as the life of the lathe spindle. In summary, the problem of damage to the lathe spindle can be classified and classified as follows.
Fatigue spalling = life, wear, vibration increase, friction torque increase, seizure, indentation, rust, corrosion, etc.
Therefore, the accuracy and life concept of the pneumatic chuck and the hydraulic chuck, the accuracy of the chuck also comes from the spindle of the lathe, and at the same time, the life can be quantitatively calculated. When discussing the durability and accuracy of the chuck, etc. It is often used, welcome new and old customers to visit and guide.
