Description
B 1.486 Bore Clamps Eccentric 

The hydraulically-operated bore clamp is particularly suitable for clamping in workpieces with smooth bore holes in the support surface ranging from 8 to 12 mm in diameter.
The workpiece is placed directly onto the hardened supports of the bore clamp and is not deformed during clamping. Since clamping is effected within the bore, the remaining surfaces are free for machining on 5 sides.

The double-acting hydraulic cylinder operates a tie bolt that is eccentrically arranged at the edge of the housing in which the clamping bolt is safely engaged.
This conical clamping bolt expands the hardened clamping bushing so that its points penetrate the bore surface in the workpiece with a positive fit (see “Clamping principle”).

Clamping bolt and clamping bushing can be exchanged very quickly after loosening the workpiece support. The bore clamp can remain on the fixture and no hydraulic oil escapes.
All functions can be monitored pneumatically. The use of the connection for positive air pressure protection prevents liquids and swarf from entering the clamping bushing.
