Page 683 | 2.3 Tensioning with Eccentric Cams and Wedge Clamps GN 411.2 Centering Bore Clamps continued Dimensions A circular ball cage containing 3 or 6 balls is forced outwards over an accurately guided cone by means of a screw which, through the exerted thrust, will enlarge the outside diameter of the circular ball cage. This in turn will lead to a firm con- tact between the centring clamp and bore of the workpiece. Type K (with balls) is used for clamping applications where minor ball marks at the contact points with the workpiece are acceptable. Type S (with clamping segments) is used in such cases whe- re marks at the clamping points on the workpiece would be acceptable. Operating principle
