Standard chuck of this machine is manual chuck， and we can offer hydraulic chuck and
electric chuck according to the requirements from the user.
Hydraulic chuck is connected with rotary oil-cylinder by link rod, the piston inside
hydraulic cylinder moves to the direction of chuck and to make the jaws of the chuck
release through the wedge type structure, and the jaws will close when the piston returns
back. The rotary oil-cylinder consists of cylinder body, single-way valve and rotary
conjunction. The single-way valve will keep the constant pressure inside the cylinder
when the oil pressure goes down unusually because of the trouble of pressure resource.
The structure of the jaws must suit the shape of the workpiece to be chucked. Some
limitations and matters needing attention were specified for ensuring the safety, high
accuracy and serving life of the chuck, therefore, it is necessary to operate according to
the specifications in “Operation Manual of Chuck”.
