tricity setting screws are parallel to the mea-
suring direction of the testing gauge. With
these concentricity setting screws and the
supplied hex key bring the indicator of the
testing gauge to 0 (fig. 2.3).
Maximum setting: 0,06 mm.
7. Turn sensor at 90°. Repeat step 6.
8. Repeat steps 6 and 7 until the indicator of
the testing gauge rests at 0 when turning the
sensor.
9. All concentricity setting screws must be tighte-
ned firmly.
2. Approaching radially
(x, y axis, view 3)
• Switch off the spindle and coolant supply.
• Clamp chuck with sensor in spindle or
erosion head. It can be installed in any
direction (horizontally or vertically).
• Check resting position of dial gauge.
The long indicator of the dial gauge (1/100
scale) must show vertically to 0 while in resting
position. Possibly turn the scale ring. Should this
resting position change, return sensor for exami-
nation to manufacturer or distributor.
• Turn spindle so that the dial gauge is facing
the operator. The turning angle doesn't mat-
ter. The sensor works in every direction.
• Slowly approach workpiece with sensing
ball. The approaching motion must follow ver-
tically to the workpiece surface. The sensing
ball must not run along the edge of the work-
piece (could lead to errors in measurements).
• During the approaching procedure do not
twist the sensor (could lead to errors in mea-
surements).
• As soon as the sensing ball has touched the
workpiece, the spindle axis is 2 mm / 0.079
in. in front of the workpiece edge (when
using the long probe tip: 4 mm / 0.157 in.).
From here on the distance between spindle
axis and work-piece edge is indicated with
correct sign (long probe tip: double the mea-
surement on the dial gauge; one unit = 0,02
mm / 0.00079 in.).
• When the dial gauge shows 0 (both indica-
tors) the spindle axis is exactly over the edge
of the workpiece. The machine axis can now
be nulled without further calculation. Should
the 0-point be overrun, set back and
approach again.
Note:
The 0-point can be overrun without danger of
damage up to 3 mm / 0.12 in. After this a cera-
mic bond in the probe tip breaks and protects
the workpiece as well as the sensing mecha-
nism against damage. Only the probe tip must
then be replaced (see no. 6).
