Design Chucks

MULTI-JAW CHUCK (MANDRILES DE SUJECIÓN POR PERNOS MÚLTIPLES)

MULTI-JAW CHUCK (MANDRILES DE SUJECIÓN POR PERNOS MÚLTIPLES)

Thin-walled cylindrical work-pieces are easily deformed or deflected even by a small gripping, cutting, or centrifugal force, so they require difficult cutting conditions and many finishing processes. When the Multi Jaw (MUL) type Chuck adopts many clamping points and spiked jaw tips, a small force on each point can provide a strong clamping torque. UBL and Multi-Jaw Combined Chucks are also available for operations as heavy vertical lathe turning or working on pieces like 'brake drums'.

DIAPHRAGM CHUCK TYPE (MANDRIL/BROQUERO TIPO DIAFRAGMA)

DIAPHRAGM CHUCK TYPE (MANDRIL/BROQUERO TIPO DIAFRAGMA)

Diaphragm chucks 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 compressors screw mechanisms, and are also used in the body of the gear chuck body.

TYPES: Master Jaw・Diaphragm Chuck / Floating Diaphragm Chuck / GC Cage type Gear Chuck / Bevel Gear Chuck

AC TORK-LOCK ARBORS/COLLETS (MANDRIL DE EXPANSIÓN AGARRE INTERNO)

AC TORK-LOCK ARBORS/COLLETS (MANDRIL DE EXPANSIÓN AGARRE INTERNO)

TEIKOKU's Tork-Lok clamping function for internal diameters (ID) features accurately machined kinematic pair surface of the collet to the arbor providing a "locking" mechanism that prevents slippage on the contact surface even during large high torque machining. These chucks draw-clamping function provides excellent accuracy, performance, and plenty of variety.

TYPES: DRAWBAR, HAND-LOK (MANUAL), BETWEEN-CENTERS, FIXTURE

JAW PULL-BACK TYPE PIN ARBOR CHUCK (MANDRIL DE PERNOS DE JALÓN)

JAW PULL-BACK TYPE PIN ARBOR CHUCK (MANDRIL DE PERNOS DE JALÓN)

TEIKOKU CHUCK's Pin Arbor Chucks are designed for improving small size internal diameter (ID) chucking and the finishing of outer diameter (OD) workpiece clamping. Constantly innovating, TEIKOKU's PA Chuck line-up offers several different model configurations including unique and proprietary "jaw air detection" technology which deals with common dust-in-jaws problems usually found in production lines.

TYPES: PA Pin-Arbor (inside clamping), OPA Pin-Arbor (outer clamping), OPN Pin-Arbor (outside clamping), OPA swing-action (skip over clamping), OPA MICRO Air-Chuck, Special Design Arbor Chucks.

UNIVERSAL BALL LOK (UBL) SWING PULL-BACK CHUCK (BROQUERO / MANDRIL  DE JALÓN)

UNIVERSAL BALL LOK (UBL) SWING PULL-BACK CHUCK (BROQUERO / MANDRIL DE JALÓN)

Power chuck design to meet several kinds of user requirements where rigidity, durability, and superior gripping performance of cast or forged materials with either overhang or draft angles that conventional chucks can't grip. Available either as centralizing UBL (for general chucking) or compensating UBL (for center holes) types. Other options such as long-stroke, large-diameter through-hole, switch-over ON/OFF, or 6-jaw ID/OD chucking are available.
