Build & Price

Function

The head of the cam point screw has two cams: a radial clamping cam (with additional 30° taper) and an axial draw-down cam.

The cam ensures that the clamping force is the same in any angular position. The cam is also
self-locking.

Force components act on the clamping point which generates a draw-down effect and, in addition to the friction, cause the workpiece to be pressed up against a fixed stop. An additional draw-down effect is created by the thread and the 30° taper.

Assembly Instructions

•Position the threaded hole/s as specified.

•Screw the cam point screw in to the desired height and place it with its flat side facing the workpiece (note the minimum screw-in depth t)

•For clamping effect above the head taper, the minimum clamping height should be h₂

•A turn of approx. 135° is required for clamping
