Bore Clamps
bore Ø 5.5 – 13 mm
double acting, max. operating pressure 30, 80 and 120 bar
The hydraulically-operated bore clamp is particularly suitable for clamping in workpieces with smooth bore holes in the support surface ranging from 5.5 to 13 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 conical clamping bolt centrally located in the housing, which expands the hardened clamping bushing. The expansion force causes the points to penetrate into the softer bore surface. This positive connection guarantees a secure clamping of the workpiece.
All functions can be monitored pneumatically.
The use of the connection for positive air pressure protection can prevent liquids and swarf from entering the clamping bushing.
