WARNING
Make sure that proper grinding discs are always being used,
otherwise the machine or the valve body can be damaged:
If grinding discs are used for lapping operation, they will be
damaged!
If already used lapping discs are utilised for grinding operation,
the required accuracy cannot be guaranteed and the valve seat
might be damaged
The grinding pressure is applied
with the star knob of the tilting
adapter.
For best performance, the grinding
pressure should not be too high or
too low. If the grinding pressure is
too high, it might result in heat cre-
ation at the grinding disc and the
abrasive might shear off. If grind-
ing pressure is too low, it could
result in low performance.
To get the perfect grinding pres-
sure, please consider diagram
4.5.0.2. This diagram shows the
grinding pressure resulting from
the torque applied to the star knob
of the tilting adapter. The different
lines are standing for the submerg-
ing depth. The diagram gives the
values for pre-setting the pressure
and it shows that the torque at the star knob is fairly low since the ratio of the tilt-
ing table is very high.
