Regarding the angle parameters of the chuck on the CNC lathe, this depends on the specific type of chuck and the application scenario. Let me provide you with a detailed explanation:
Common angle parameters of CNC lathe tool holders

Spring-type tool holder (cylinder holder) angle
Socket taper: Commonly available in 5°, 8°, 10°, 15°, 20°, etc.
Typical specifications:
ER socket system: 8° taper (ER20/25/32, etc.)
5C socket: Standard taper is usually 5°
Angle of chuck jaws
Hard claw working surface angle: Usually 30° or 45°
Soft claw turning angle: Customized according to the shape of the workpiece, common range is 30° - 60°
Main shaft taper hole angle
BT/MBT series: 7:24 taper (approximately 16.594°)
HSK series: 1:10 taper (approximately 5.7°)
Selection suggestions
Considerations:
Workpiece shape and material
Processing accuracy requirements
Cutting force and rotational speed parameters
Auxiliary selection tools:
The clamping angle can be recommended based on the processing parameters.
The clamping angle can be optimized through vibration analysis.
Do you have a specific type of clamping head that you need to inquire about the exact angle? Or do you want to know how to optimize the clamping parameters through an intelligent approach?
