I.D. clamping chuck with a perfect pull-back function
PA Pin Arbor Chuck
Support back side of chucking pins
PA chuck supports the back of the pin for high chucking rigidity. In addition, the workpiece is securely adhered to the stopper for accurate clamping without horizontal deviation.
PA chuck offers as high as 0.01 TIR of chucking repeatability.
PA chuck is best suited for auto-loaders and robnot operation because of the large unclamping motion.
PA chuck enhances the cutting force with powerful I.D. clamping.
PA/OPA are possible to do also air detect in the jaw section!
The stop's air detection system has been adopted a lot in the chucks for the FA production line, however, the jaw air detection system had some structural difficulties. TEIKOKU CHUCK, as a developer of the jaw "pull-back" type design & Pin Arbor chuck, developed the "Air Detecting Jaws" Pin Arbor chuck which is featured the air sensor in the jaws through the chucking pins.
This function enables to solve the problem caused by the dust on the jaws which had been thought as a weak point in the FA production line.
Jaw Pull-down Chucking in the half a century.
In 1977, we developed jaw pull-down type PA for the durable and the performance improvement of conventional small size I.D. collet chucks, and in 1980 developed OPA for the finish processing of O.D. clamping workpieces.
Since then, we are trying to develop the new-type jaw pull-down Design Chucks and propose to select our various jaw pull down formula design [e.g. the OPA-Swing Chucks and the Micro OPA etc.]
