|Check the perpendicularity of the turret face to the center line of the main spindle. Place the dial indicator to the face of the chuck and measure the face of the turret while the X-axis is moving in either the (+) and (-) direction. The face could be tilted back to the maximum amount of 0.001/6″ on the top. Check the center line of the tool holder pocket to the center line of main spindle. Place the dial indicator to the chuck and move the turret to the center in X-direction by swinging the base with the chuck . The dial tester should be in the ID tool holder hole. The center can be higher by 0.001-.003″ in the A direction
Adjusting the tilting of the turret
- Loosen the bolts that are fixed to the turret body (the turret tilts around the bushing which is between the turret body and the sub-plate at the 2nd bolt on the top).
- Adjust the tilt by checking the face of the disc. In case of a big collision, make sure that the plate between the turret and the cross slide did not move. If it happened, simply take off the turret, adjust the plate, and replace the taper pins. After the plate is secured, put the turret back, align it, and tighten the bolts securely.
Adjusting the height of the tool holder centerline of turret disc
- Pull out the taper pin. Normally, a pin puller is required for this task. (However, not every turret disk has a taper pin, because at normal cutting conditions, the front bolts hold the disk securely.)
- Loosen the bolts at the face of the disc
- Adjust the turret disc by watching the swing of the dial indicator, while the dial tester is inside the hole of the ID tool holder (a rubber hammer will suffice to adjust the disc).
- Tighten the bolts securely.
- Insert the new taper pin. (10mm at small end, 45 mm long). In case of a big collision, make sure the hole is reamed for the taper pin.
