OPA Swing Chuck

Design chuck equipped a swing-clamping function in the jaws of the OPA chuck

High-Precision Skip-Over Clamping Function
Skip-Over Clamping for Irregular-Diameter Workpieces.

The OPA-Swing Chuck is designed to clamp irregular-diameter of the work-pieces in large-volume production. This new chuck features a swing-clamping function in the jaws of the OPA chuck, O.D. clamping high-precision Pin Arbor Pull Back chuck, in order to skip-over the larger diameter end face of the work-pieces and accurately hold the proper smaller-diameter clamping portion.
The entire chuck design including the swing direction and angles can be determined according to individual work-pieces and conditions of operation.
Also, not only skip-over clamping function, but also it is possible to insert the work-pieces from the side of the chuck, which allows to give you a wide range of options to chose the automatic work-pieces loading methods.

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.]
