3.7 Gantry system
The gantry system of the SIPLACE SX1/SX2/DX1/DX2 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/DX, the gantries
have the same design. This machine can be equipped with either one or two gantries. The SI-
PLACE SX2/DX2 has gantries 1 and 2 which are fitted at an angle of 180°. The placement heads
are fitted to the inside of the gantry.
