Z -axis with car riage
Fig. 8a: Z-Carriage
1 Trapezoidal thread spindle
2 linear guides
The two linear guides (Fig. 8a /2) guide into the inclusion of the
accessory bracket. The trapezoidal threaded spindle (Fig. 8a / 1)
represents the Z-axis on which the accessory holder with a
suitable tool (43H7 inclusion) moves along the Z-linear guides

1 Reference switch Z-axis
2 Magnetic contact
The reference switch (Fig. 8b / 1) responds to the magnetic field
of the incoming homing magnet (Fig. 8b / 2).
If the magnet is
close enough the reed sensor of the switch turns on.
The reference switch operates as closing contact;
in switched
state the signal circuit is closed.
NOTE:
Reference switches are required for axes without absolute position encoder to
feature in the initialization of the axis by a known reference point (zero point of the
axis). From this position, all other positions are then calculated relative to the
process of the axis via software.
