Hydraulic Lock Nut use for clamp hob arbour For gear hobbing machine.
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.
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
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
