Precision capability
Absolute centreing – The diagrams adjacent illustrate how the gripping sleeve of hydraulic arbors conform to the part bore surface. This ensures part positioning on the true axis whilst compensating for acceptable component geometry variations such as taper, bell mouthing, barrelling and out of round.

Size Availability
Arbors – minimum component size 6,00mm (.240”)
Chucks – minimum component size 1,00mm (0.40”)
Maximum component size is unlimited for both types of workholder but dependent upon component type, part tolerance and operation requirements.

Gripping Force – Acugrip hydraulic work-holders are individually designed to locate the component with the correct gripping force for each application. This force ranges from hundreds to several thousand pounds per square inch and is ideally suited for most high accuracy production operations together with sensitive inspection requirements.

Expansion Limits – The amount of expansion is controlled by the tried and tested elastic limit of the sleeve material used and is shown in table. Workholding can be supplied to suit component tolerances in excess of these figures but is subject to application.
