The unit has two working platforms. The goniometer on left is used to measure a high precision wafer. On right the quartz bar orientated on its R-face is adjusted by a micrometer. The cutting angle is adjusted by the goniometer. This unit is mainly used for AT- or BT-cut.

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.
