1 Linear guides on the Y-Bridge
2 Tool holder (43H7 holder)
3 Y-bridge
4 Trapezoidal threaded spindle (also behind the cover)
The two linear guides (Fig. 9a / 1) and the Trapezoidal Thread
Spindle located on the Y-bridge (Fig. 9a / 3) and represent the
Y-axis. Along the Y-Bridge is the tool holder (Fig. 9a / 2) which
can be moved with a suitable tool (43H7 holder)

1 Reference switch Z-axis
2 Magnetic contact
The reference switch (Fig. 9b / 1) responds to the magnetic field
of the incoming homing magnet (Fig. 9b / 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.
