– 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.
|Features and applications||
Cam point screws GN 418 are simple clamping elements for a wide variety of different uses. They are sturdy and compact elements, requiring a minimum of installation space and offering ultimate convenience and ease in handling. <BR><BR>The clamping forces F given in the table refer to the maximum permitted tightening torque and the specified screw-in depth t. <BR><BR><BR><BR>
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.
Case hardened HRC 56 ±1.<BR>- Type <STRONG>R</STRONG>: Zinc plated steel, blue passivated.<BR>- Type <STRONG>L</STRONG>: Blackened.<BR>
|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).
