TIR Adjustment

4 Opposite side

3 Opposite side

Step 1: Place the tool into the machine spindle. Make contact with the four radial adjust ment screws in a concentric fashion (this results in equal pressure surrounding the tool). Tighten #1, then #3, followed by #2 and #4.

Step 2: Swipe the dial indicator around the ground porƟon of the arbor near the coolant outlet holes to verify the TIR. The TIR should be within 0.013 mm (0.0005") (as close to 0 as possible). This will ensure the TIR check on the cuƫng teeth will be more true. It also means the arbor is running true to the shank. Step 3: Once the TIR is checked on the arbor, check the TIR on the cuƫng teeth. Rotate the tool counterclockwise to avoid chipping the cuƫng teeth.

Clamping Screw

Step 4: Tighten down the central clamping screws. During the Ɵghtening, the tool body will shiŌ slightly. Repeat the TIR check on the cuƫng teeth and adjust as necessary.
