Automatic Back Spot Facing Tool, Rear Counter Bore Tool ASSEMBLY

Press the pivot pin in the bore, provided on the tool shank. Position the wing in the pocket through the pivot pin. Screw on the pivot screw through the tapped hole till its point enters the cone, provided in the bottom of the wing. Tighten the pivot screw till the clearance between the pivot pin and pivot screw is just sufficient for the wing to freely swing in and swing out of the pocket, at the same time avoiding any axial and radial play. Lock this position by tightening the lock screw through the aluminum binder. It is advisable to release the pivot screw by about 30% before locking, so as to nullify the possible thermal expansion during cutting. Do not over tighten the insert clamping screw. Solid HSS wings are with integral pivot pin. Regrind the blunt cutting edges of HSS wings.
