The gantry is fixed to the two shuttles (see item 1 in Fig. 7.2 - 3) of the recirculating ball screw unit
(see item 2 in Fig. 7.2 - 3
) using four M6 x10 hexagon socket-head screws.
The secondary part (see item 3 in Fig. 7.2 - 3
) of the Y-axis linear drive, with its permanent mag-
nets, is located above the guide rail of the recirculating ball screw unit. The secondary part is
mounted on the machine frame.
The air and power supply and signal lines for the gantry and collect&place head all run in a trailing
cable (see item 1 in Fig. 7.2 - 4
).
The seven power cables take the form of flexible ribbon cables, four of which are needed for the
collect&place head. They run beneath the cover in the machine frame (see item 1 in Fig. 7.2 - 5
),
between the head board on the head mount and the gantry board.
