Fasten workpiece holder
Img.4-9:
Fasten workpiece holder
Turn clamp bolts (1) into the open position.
Clean the taper attachment on the lathe chuck and the spindle fixture.
Fit lathe chuck.
Turn the clamp bolts (1) to the closed position.
CAUTION!
If the reference mark on the clamp bolt is not between the two V markings, the chuck
must be removed and this bolt (D) must be re-adjusted.
Fasten the workpiece holder by turning the clamping bolts clockwise.
The right clamp position is reached when the reference marker at the clamp holder are between
the two marks at the lead spindle seat.
The tightening torque must be approximately 80 Nm, otherwise the rotational accuracy of the
lathe chuck is not present. 100 Nm is about the torque used for aluminum rims on cars.

4.13.1 Adjusting the Camlock bolts to the workpiece holder
Insert all of the bolts in the screwed flange of the chuck, until the reference mark, the circular
reference line (F) is in line with the wall of the chuck flange surface and the semicircular
grooves are in line with the holes of the safety screw (E).
Fit the safety screw (E) into each bolt and tighten.
Make sure that the two contact sides (plate and shaft) are free from impurities.
Now the chuck can be mounted.
Before coupling the chuck to the shaft nose, check that the clamp bolts are in an unlocked
position.
Fasten the workpiece holder by turning the clamping bolts clockwise.
