Design chucks

爪引込式 ピンアーバーチャック SOUL-Woodworthシリーズ

Jaw Pull-down Chucking in the quarter of 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 latest OPA-Swing Chucks and the Micro OPA etc.]

Jaw air detection specifications with the Pin-Arbor Chucking Design.

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.

PA Pin Arbor Chuck

For I.D. Clamping

  • PA chuck securely draws the workpiece into the stopper and accurately clamps it without horizontal deviations.
  • PA chuck offers as high as 0.01 TIR of chucking repeatability.
  • PA chuck is best suited for auto-loaders because of the large unclamping motion.
  • PA chuck enhances the cutting force with powerful I.D. clamping.

OPN Pin Arbor Chuck

For O.D. Clamping / Soft Jaw type [Design]

Excellent form for jaws mounting.

The OPN Pin-Arbor Power Chuck is O.D. clamping power chuck which is excellent at controlling parallelism and thickness with having "pull-back" clamping function. Furthermore, OPN chuck features soft jaws system having excellent repeatability and interchangeability which allows any user to form soft jaws by themselves following the jaws forming procedure and assemble them to every same inch size of OPN chucks with keeping high-concentricity.

NEW FUNCTION – OPA Swing Chuck

[Skip-Over Pin Arbor Chuck] PAT

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.

NEW type Micro OPA Air Chuck

[Small size Precision PIN-ARBOR Chuck] Built in Air Cylinder

Small size PIN-ARBOR Chucks with built-in air cylinder for precise turning processing.

  • With the built-in air cylinder, concentricity become less than 0.005 T.I.R. of chucking repeatability.
  • Securely draws the workpiece into the stopper and accurately clamps it without horizontal deviations.
  • Extremely suitable for high-speed turn because of light weight jaw and supported by chuck body.
  • MICRO-OPA is designed based on user needs and delivered as the finished good. So the customer will be able to use MICRO-OPA reliably.

SPEICAL Jaw Pull Back Design Pin Arbor Chuck

A Broad Range of Selection

Pin-arbor chucks have excellent chucking function, but only in the standard specification available workpieces to manufacturing are limited.
We have been developing various special pin arbor application designs to the request of the high risk from the customer.

  • Double Pin-Arbor

    Suitable for finishing process of the pipe-shape workpieces.

  • Multiple Pin type

    The air compressor parts to process by clamping a hole with five equal angles.

  • OPA & Finger Jaw

    After centering periphery of thin workpiece lightly by OPA, clamping surface of it's flange by finger jaws.

  • OPA & Face Clamp

    The 6 jaw OPA /Centering softly by three jaws and Face-clamping by another three jaws.

  • OPA & Finger Jaw

    The 2nd processing of knuckle back. After chucking finished O.D. by OPA, finger-clamping the surface for safety.
