Calculation
of the offset of the top slide relating to the stop measure with a length of 100 mm.
Step by step
L
Kv =
D - d
by one calculation step (summary)
100 mm x (D - d)
Vo =
2 x L
Example:
D = 30.0 mm ; d = 24.0 mm ; L = 22.0 mm
100 mm x (30 mm - 24 mm)
Vo =
2 x 22 mm
The stop measure (100mm) is to be put between a fixed unit stop and the bedslide. Put the
gauge with stand on the lathe bed and horizontally align the test prod with the test prod with
thetop slide (90° to the top slide). The twisting measure is calculated with the above mentioned
formula.
The top slide is twisted by this value (then set the gauge to zero). After removing the stop
measure, the bedslide will be aligned to the limit stop. The gauge must indicate the calculated
value "Vo" Then the workpiece and the tool are clamped and positioned (the bedslide is fixed).
The infeed is performed with the handwheel of the top slide. The depth of cut is advanced with
the handwheel of the cross slide.

The stand is put on the top slide. The gauge is aligned horizontally and 90° to the top slide. The
top slide is approximately adjusted to the cone angle and the test prod brought in contact with
