JATO JAM/JHM Series Spindle Collet Chuck is specially designed to provide users with the best solution to design and build their special purpose machines.
A traditional power workholding system consists of a rotary spindle, a power chuck, and a rotary cylinder. JAM/JHM Spindle Collet Chuck combines these three elements in one, making machine builders very easy to design and build special purpose machines with workpart auto-loading and CNC controlled machining. Since we also longer the chucking length of the collet, JAM/JHM Spindle Collet Chuck is mostly used to chuck double-ended work parts like hubs of bicycle wheels or piston rods of automobiles.
An integration of rotary spindle, power collet chuck, and air/hydro actuator.
Specially designed for double-ended machining: Saving setup, loading, and machining time.
Accelerates the designing and building cycle for a new special purpose machine.
Compact size.
High clamping force. High rigidity.
