6.8.4

Transferring the basic dimension to the VG2 presetting device

•

Fit the dividing head into the central mount of the VG2 presetting device and
screw it tight.

•

Check the radius midpoint by swivelling the dial gauge.
– If the gauge indicates a deviation, you must first of all loosen the four M6

hexagon socket bolts in the axial mount. Then adjust the axial mount by tap-
ping it gently and re-tighten the bolts.

•

Set the dial gauge to zero = BASIC DIMENSION.

•

Check the adjustment by inserting the dividing head into the turret head of the
PA 31K again and swivelling it 2 x 90° as described above.

6.8.5

Adjusting the diamond reference dimension

•

Swivel the dividing head 180° and mount it in the VG2 again. The gauge block
should now be parallel to the dial gauge.

•

Tighten the fastening screw again.

•

Calculate the reference dimension for a calibrated ball diameter of 6 mm, with
a gauge block of 3 mm minus the radius of the diamond that is to be used. Ad-
just the gauge block so that the dial gauge shows the basic dimension again.

•

Now remove the gauge block and set the dial gauge to zero.

The base of the dial gauge must be aligned exactly in the vertical
direction.
