U ASA II HERMETICALLY SEALED POWER LATHE SELFCENTERING CHUCK WITH DRAW-DOWN ACTION FOR GRIPPING AND CLAMPING: PRECISE-RIGIDIRREVERSIBLE. All U ASA II Rotomors are hermetically sealed to prevent penetration of dust, coolant and chips. All internal moving parts operate in an oil bath to offer absolute reliability and constant clamping force. For horizontal and vertical application in mass production. Clamping jaws are designed according to the workpiece size, with all clamping and rest points performed in relation to the operating cycle. Jaws with micrometrical adjusting realized directly on...

QUICK RELEASE JAWS All Rotomors u asa ii are designed for high production with a quick release jaws system. Each jaw can be changed in less than 15 seconds in an easy, safe and quick way. U ASA II - 3 HERMETICALLY SEALED POWER LATHE SELFCENTERING 3 JAWS CHUCK WITH DRAW-DOWN ACTION SUITABLE FOR MULTISPINDLE PRODUCTION LATHES - aws with micrometric radial adjustment which j ensures concentricity on the machine - internal-external clamping Used in the machining of drum brakes, bevel and ring gears, hubs, shafts and other automotive mechanical components for mass production.

U ASA II - 6 2+2 HERMETICALLY SEALED POWER LATHE SELF-CENTERING 6 JAWS CHUCK BALANCED 2 BY 2 WITH DRAW-DOWN ACTION This system with 6 balanced jaws is made of 3 pairs, and each has an internal link which allows them to balance in sets of two. This system with 6 forces moving towards the center, avoids the deformation of the component. The pendulum jaws arranged in pairs provides a coaxial tolerance of 0.02 mm in mass production and 0.01 mm in single piece production while simultaneously ensuring precision positioning without triangular deformation. Used for horizontal and vertical...

U ASA II - SAG 3 HERMETICALLY SEALED POWER LATHE SELFCENTERING 3 JAWS CHUCK WITH DRAW-DOWN ACTION AND ANGULAR POSITION WITH SERRATED FRONT COUPLING For machining of: crank pins of crankshafts. The accuracy of the machining is performed by 3 concentric jaws. - axial point as reference - angular position with serrated front coupling - built-in microdetectors to check the functions.

ApplicationS on demand U ASA II - SP 3+3 HERMETICALLY SEALED POWER LATHE SELFCENTERING 3+3 JAWS CHUCK ON TWO LEVELS WITH DRAW-DOWN ACTION For external clamping of: pistons liners. For the operations of: internal turning. The two sets of 3 self-centering and draw-down jaws work independently on two levels in order to warrant centering, perpendicularity and draw-down of the workpiece on the rest ferrules. The body is completely sealed and all internal parts are in an oil bath. The jaws have floating contact sectors to help the clamping on the rough outside surface of the workpiece. The action...

U ASA II - SM 6 2+2 HERMETICALLY SEALED POWER LATHE SELFCENTERING 6 JAWS CHUCK BALANCED 2 BY 2 WITH DRAW-DOWN ACTION Used for machining of: carbon discs or other special disintegrant material. All internal moving parts operate in an oil bath to prevent penetration of dust, coolant and special material cips and offer absolute reliability and constant clamping force. For horizontal and vertical application in mass production. U ASA II - S2L 3+3 HERMETICALLY SEALED POWER LATHE SELFCENTERING 3+3 JAWS CHUCK ON TWO LEVELS WITH DRAW-DOWN ACTION Used for machining of: differrential housing.

Applications on demand U ASA II - S3R 6 2+2 HERMETICALLY SEALED POWER LATHE SELFCENTERING 6 JAWS CHUCK BALANCED 2 BY 2 WITH DRAW-DOWN ACTION AND 3 RADIAL POSITIONS For clamping of: bearing rings. For machining of: - outside turning diameters from 930 to 290 mm - inside turning diameters from 830 to 230 mm. To allow the outside or inside clamping on a very large range of diameters, the jaws are radially movable in 3 positions; this shifting is actuated by a rapid manual extraction and introduction of the jaws-holder in the relative radial seats. The jaws-holders serrated mounting surface...
