Additional information

Assembly instructions

– Position the thread bore(s) as specified. <BR>- 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). <BR>- For clamping effect above the head taper, the minimum clamping height should be h<SUB>2</SUB>. <BR>- A turn of approx. 135° is required for clamping. <BR>

Cam

Black oxide steel, case hardened all around, HRC 56 ±1.

Features and applications

Cam point levers GN 418.1 have the same mode of action as the cam point screws GN 418. <BR><BR>The ball-type handle is connected to the cam point lever via a serration, allowing the correct clamping position to be set and the lever to be re-adjusted. <BR><BR>The clamping forces F shown in the table refer to the maximum permissible tightening torque and to the specified screw-in depth t see Cam point levers GN 418.

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. <BR><BR>The cam ensures that the clamping force is the same in any angular position. The cam is also self-locking. <BR><BR>Force components act on the clamping point which generate a drawdown effect and which, in addition to the friction, cause the workpiece to be pressed against a fixed stop. An additional draw-down effect is created by the thread and the 30° taper. <BR><BR>To ensure safe and secure clamping in every application, a right-hand version (with right-hand thread) and a left-hand version (with left-hand thread) is available.

Lever

Black-oxide steel.

Standard versions available

– Type <STRONG>R</STRONG>: clamping by clockwise turn (d<SUB>2</SUB> = right-hand thread).<BR>- Type <STRONG>L</STRONG>: clamping by anticlockwise turn (d<SUB>2 </SUB>= left-hand thread).

Thread

Black oxide steel, case hardened all around, HRC 56 ±1.
