Abstract
An adjustment mechanism for adjusting an insert pocket wall's abutment surface in order to alter the location of an insert mounted in the pocket. The adjustment mechanism includes an adjustment screw and adjustment ball located in an adjustment bore. The adjustment ball is located in the vicinity of the pocket wall and on tightening the adjustment screw the adjustment ball is forced against the pocket wall. The force applied by the adjustment ball deforms the pocket wall in the region of contact between the adjustment ball and the pocket wall resulting in the required adjustment of the abutment surface.

In a cutting tool an insert pocket adjustment mechanism comprising:
- an adjustment bore (46) having a rear portion (48) and a forward portion (50), the forward portion being located in the vicinity of an insert pocket wall (20, 24);
- an adjustment member (38) located in the rear portion (48) of the adjustment bore (46), the adjustment member (38) having a front end (40) adjacent the forward portion (50) of the adjustment bore (46);
- and
- an adjustment ball (44) located in the forward portion (50) of the adjustment bore (46) adjacent the insert pocket wall (20, 24), the arrangement being so that on urging the adjustment member (38) into the forward portion (50) of the adjustment bore (46), the front end (40) of the adjustment member (38) engages and forces the adjustment ball (44) into contact with the forward portion (50) of the adjustment bore (46), as a result of which the adjustment ball (44) applies a force to the pocket wall (20, 24) for altering, through deformation, the location of at least a portion of the pocket wall (24).
