ROEMHELD Bore clamps

 

A particularly space-saving possibility of workpiece clamping.
The bore clamp are particularly suited for clamping of workpieces with
smoothbore 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.


The benefits at a glance:

•  axial clamping in simple bore holes allows 5-side machining and optimum workpiece accessibility
•  hold the workpiece without hydraulic pressure to increase the machine safety
•  pneumatic seat check for use in automated applications
