INDUSTRIAL DESIGN CHUCKS

With more than 90 years of foundation, TEIKOKU CHUCK Corp. gathers almost a century of knowledge and experience in the development of industrial brokers and fastening systems. From 1969, in partnership with North America Woodworth Co. (USA) - now FORKARDT Inc. -, the "Design Power Chuck - SOUL" line is launched, which is the representative bastion of TEIKOKU worldwide.
Having as customers the main Japanese automakers for a long time, TEIKOKU is backed with the confidence of its customers with the safe performance of its products.

The main lines of products are:
  • UNIVERSAL BALL LOK Chucks (pulling)
  • PIN ARBOR Chucks (Opening or closing pins)
  • TORK-LOK (expanding collets)
  • Tipo diafragma (pneumatic action)
  • MULTI-JAW Chucks(multiple pins for soft pieces)

DESIGN-POWER CHUCKS

DESIGN-POWER CHUCKS

It was developed through a technical link (in 1969) between N.A.Woodworth (FORKARDT / now) in the USA. UU AND TEIKOKU CHUCK in JP. They are designed to meet various types of individual user needs and are considered to be number one in Japan for their rank and track record. TEIKOKU CHUCK is a company that manufactures Design-Chucks to hold various types of parts.

MANDRIL MULTI-JAW

MANDRIL MULTI-JAW

Thin-walled cylindrical workpieces are subject to elastic deformation even under a small force, such as clamping force, cutting resistance or centrifugal force. Therefore, this type of work pieces require several countermeasures, such as ensuring the precision of the roundness or preparing the special mandrels and cutting tools for antivibration, and add some additional operation.
The MUL mandrel has the floating mechanism that allows the surface of the thin-walled cylindrical workpieces to be clamped with the same force and is effective for pieces of material of uneven material. In addition, the Multi-Jaws feature allows for a smooth and strong clamping torque without deforming the work pieces and also adding more rigidity in the processed part. It is then possible to obtain the precision of roundness in the first operation, even when molded and forged deformable molded parts are processed, or pressed under pressure.

TIPO DIAFRAGMA Y MANDRIL DE DIAFRAGMA Y ENGRANE

TIPO DIAFRAGMA Y MANDRIL DE DIAFRAGMA Y ENGRANE

Diaphragm mandrels feature high levels of elastic retention precision and a reliable structure that can prevent deterioration of accuracy due to internal wear and chips. For that reason, they are mainly used for high-precision finishing operations, such as the machining of displacement compressors, and are also used in the body of the gear chuck.

PINZA DE SUJECCION AC TORK-LOCK

PINZA DE SUJECCION AC TORK-LOCK

The standard series is designed to cover a wide range of internal diameters from 12.7 mm to 113.4 mm.
In comparison with the type of short-range drawbar, this offers greater flexion tolerances and greater resistance against frequent idling operations, so its use is recommended for short parts that require a limiter (for nozzle opening) .

PIN ARBOR CHUCK

PIN ARBOR CHUCK

Improvement of the conventional small size of grippers for internal diameters, and in 1980 developed OPA for the final process of external diameters and gagged parts.
Since then, we are trying to develop the new type of deployable jaw design mandrels and we propose to select our design of several types of deployable jaws.

TIPO SWING PULL-BACK

TIPO SWING PULL-BACK

This is a general type jaw with the part of the gagging centered and with the face of the stop aligned with the face of the edge. This type of clamp reliably holds even cast / forged raw material pieces with a setting (up to 20 °) to ensure a constant dimensional accuracy in the axial direction even during high strength cutting. The structure of two or more jaws is available. The clamp can be easily changed for either mandrel OD (outer diameter) or DI (internal diameter). The jaws, plugs and other upper parts are designed according to the individual needs of the customer. In addition, a wide variety of jaws can be selected for various types of parts. The carbide insertion jaw and the special form clamp are effective for machining difficult-to-cut materials. The high strength aluminum clamp is suitable for high speed machining. The master / jaw type and the quick-change jaw system (Q.J.C.) are useful for machining many types of workpieces / small parts.
The compensation type is designed to allow the jaws to clamp a workpiece with equal forces along the perimeter of the workpiece with respect to the central / main holes. The structure of two or more jaws is available. All parts, except the actuator, are equal to the type of centralization. The UBL compensating type jaw offers a wide range of jaws, depending on the main and central holes. In addition, this type has excellent profitability and great adaptability to cutting complex shapes and high load machining, as well as high levels of precision and maintenance. In addition, special jaws, fixed center, reference pin, dynamic balance correction, combination design, etc. can be used. according to the individual requirements of the customer in terms of machining accuracy, cutting conditions and grip shape.
