How to choose the right chuck model for your machine?
Please fill in the following.
Would you like a rotary type or a fixed type chuck?
Rotary (Rotary Type):
The chuck rotates together with the machine tool spindle,
making it suitable for workpieces that require continuous rotary machining.
Fixed (Fixed Type):
The chuck is mounted on the machine bed and does not rotate.
It is mainly used for workpiece positioning and clamping, and works with other axes to perform feed machining.
