Product introduction
NTH JAM/JHM Spindle Collet Chuck is specially designed to provide the users with an all-in-one solution to build their special purpose machines. A traditional workholding system consists of a rotary spindle, a power chuck, and a actuator. JAM/JHM Spindle Collet Chuck combines these three elements in one, making machine builders very easy to design and to build a new special purpose machine. Since the gripping length of JAM/JHM Chucks are longer than regular collet chucks, JAM/JHM is mostly applied to grip double-ended work parts like hubs of bicycle wheels or piston rods of automobiles.
