These units have two working platforms. The goniometer on left is used to measure a high precision wafers.
The setting platform on the right is for quartz bar sticking. The R-face is
taken as the basic side of quartz bar and adjusted with a micrometer. The
cutting angle is adjusted by the goniometer. These
units are used mainly for AT- and BT-cut. There are four types of
designed to meet different demand of client. The crystal bar is stuck with +X
face upwards in DX-5A/5B units
and downwards in 6A/6B
units. The DX-5B/6B units are for cutting a broad bar.

1 The area of R-face must be big enough for
sticking. For a Y-bar it is better to cut off a piece of the bar which is parallel
to the large R-face to enlarge the sticking area.
2 It is negotiable if the demand of sticking
plate size and sticking layer is other
than listed above.
