HQJC
*You can watch the gripper replacement accuracy test video at the bottom of the page!
This is our proprietary gripper replacement system, an evolution of the QJC and ROBO-QJC.
The MMK Original Double Slide offers excellent rigidity and durability.
Gripper replacement can be performed quickly without the need to align serrations.
Repeatability accuracy for gripper replacement ≤ 10 μm.
The top-jaw replacement design prevents chip intrusion.
HQJC grippers have no bolt holes, making R-shaped machining easy,
Since the edges do not protrude, the workpiece is less likely to be scratched, improving finishing accuracy.
Both automatic and manual gripper replacement via a robot arm are possible.
When used in conjunction with Smart Terrace AIO, automated operation—including setup changes—is possible.

・The HQJC chuck secures the jaws by utilizing the reaction force generated when gripping the workpiece or the jaw forming ring.
・When the chuck is empty (i.e., no gripping reaction force is generated), the jaws are not fully secured.
・Rotating at speeds of 100 (r.p.m.) or higher is dangerous, as centrifugal force may cause the jaws to fly off.
・Do not rotate at speeds of 100 (r.p.m.) or higher when the chuck is empty.
・Additionally, depending on the situation, please install an interlock or similar safety device on the mounting machine.
