Three jaw chuck, three jaw chuck is composed of a large bevel gear, three small bevel gear, three jaw. The pitch of the rectangular thread is equal, so the movement distance of the three claws is equal. It is a workpiece that uses a voltable wrench to rotate the bevel gear, and the bevel gear drives the plane rectangular thread, and then drives the three claws to move.

The four-jaw chuck uses four lead screws to drive the four claws respectively, but it can be used to install a variety of rectangular and irregular workpieces by adjusting the position of the four claws.

The six-jaw chuck is driven by six screws respectively, but various rectangular and irregular workpieces can be installed by adjusting the position of the six claws.

Special chuck, it is mainly in order to change the diameter and shape of the claw surface at any time according to the actual needs of the workpiece, in the turning batch of larger workpiece, in order to improve the positioning accuracy of the workpiece in processing and save the auxiliary time of the workpiece installation, soft chuck can be used.
