VERTICAL COAXIALITY
INTRODUCTION
The Vertical Coaxiality program is used to
determine the direction of the rotational axis
of a secondary spindle or a tool holder, in
relation to a main spindle in a machine tool.
The axis of rotation in the main spindle is
used as a reference and the axis of rotation of
the other object is measured in relation to
that. The result is presented as an angular
and offset deviation in two directions.
The Coaxiality program is also used to
monitor the actual position of the secondary
spindle or a tool holder during adjustment.
During adjustment, the program shows the
offset and angular misalignment live in both
directions.
MEASUREMENT METHOD
The angular and offset error of the secondary
spindle (or tool holder) is determined by
measuring the distance between the rotational
center of the main and secondary spindle in
two planes.
The MEAX SR sensor is mounted on the main
spindle (reference) and the MEAX SM sensor
is mounted on the secondary spindle (or tool
holder). The distance between the sensors
