(6) Gantry arm
(7) Length measurement system
The gantry arm is made of a carbon fiber composite. This technology allows assemblies to be
made with extremely low weight and high rigidity.
The X axis is driven by a linear motor. The secondary part of the drive consists of a permanent
magnet and is mounted on the gantry arm. The primary part is bolted to the head mount. The head
mount has been designed so that all placement head types can be accommodated - one of the
benefits of the great flexibility in the SIPLACE machines.
