Description

Hydraulic Locknut for Clamp Hob Arbour Ger gear hobbing operation. The Clamping Principal: The actuation of the pressure screws or the addition of the hydraulic medium activates the self-contained hydraulic system with the pressure transformation. The amount of acting clamping pressure can be identified and monitored via an integrated pressure indicator. Hydraulic Retract: Our hydraulic lock nuts are also available with hydraulic retract. Constructions with hydraulic retract reset the hydraulic pressure automatically to the zero/starting position as soon as the pressure breaks down. Feature Double anti-leak Protection Rechargeable Clamping up to 70 K/N Purely axial clamping force - the part remains in its present position Defined and repeatable clamping force -clamping remains the same from operator to operator Much higher clamping force when needed - an advantage for holding large workpieces Floating clamping face - compensates for a face run out of spacers and provides full-face contact During the clamping procedure, no radial forces are introduced - does not induce run out to cutter or workpiece No hammers used on precision arbors and/or spindles - protects against damage to precision machine components Elimination of cheater bars for large workpiece clamping - reduced risk of operator injury and potential of workman's compensation claims Alignment rings available to true both ends of the cutter - ability to have cutter run true over its length Libheral Eaton Mitsubishi hobbing Raisauer Pfauter
