3.6 Gantry system
The gantry system of the SIPLACE SX1/SX2 machines is a so-called H gantry. This consists of
two Y axes which are driven from both sides by linear motors. The X axis is driven by one linear
motor. The H gantry runs over a fixed and a loose bearing along the bearing surface of the two Y
axes. These surfaces are at an angle of 45° to the gantry. The linear scales for the Y measuring
system are located under these bearing surfaces. In the SIPLACE SX, the gantries have the same
design and can be equipped with either one or two gantries. In the SIPLACE SX2, gantries 1 and
2 are fitted at an angle of 180°. The placement heads are fitted to the inside of the gantry.
