Bore clamps Advantages ● Axial clamping in simple bore holes ● 5-sided machining possible ● Expand clamping bushing with spring force ● Hold workpiece without hydraulic pressure ● Clamp workpiece with adjustable hydraulics ● Hardened workpiece support ● Pneumatic seat check ● Connection for positive air pressure protection ● Standard FKM seals ● 2 sizes available The bore clamps are particularly suited for clamping of workpieces with smooth bore holes from diameter 7.8 to 17.7 mm in the support surface. The required form-fit in the bore hole is obtained by the special profile of the hardened clamping bushings with penetrating points in the bore hole wall. Hardened materials cannot be clamped with these elements. The workpiece is put directly onto the bore clamp and will not be deformed during clamping. Since clamping is effected within the bore, the remaining surfaces are free for machining on 5 sides. The size of the possible machining forces is certainly limited using this type of clamping, especially crosswise to the clamping surface. Except the static friction force between the workpiece and the support, the bore clamp cannot compensate any side loads. Additional stops or positioning elements can help in such applications. Workpiece sections that are subject to vibrations and deformations during machining, have to be additionally supported or clamped in a flexible (floating) position. block, flange and cartridge type without centring function double acting for bore diameter 7.8 -17.7 mm max.operating pressure 250 bar expansion force , radial: 9-14 kN
