We're hosting a factory tour! May 16
HQJC offers fast, precise, long-lasting, and automation-compatible claw replacement.
Previously known as the ROBO-QJC Chuck, it has evolved into the HQJC Chuck through continuous technological refinement.
This is our top-recommended chuck, packed with our commitment to manufacturing excellence.
While we claim a repeatability of ≤10 μm Chuck jaw exchange,
To address the question, “Is this level of precision truly achievable even when the exchange is performed by a robot…?”
We are pleased to announce a tour where you can witness a grip accuracy test of the automatic chuck jaw exchange system in action on our in-house equipment!
We apologize for the inconvenience during your busy schedule, but we would be delighted if you could take this opportunity to join us.
