ALL-CKMD400型晶棒参考面X射线定向仪
ALL-CKMD 400 MODEL X-RAY CRYSTAL ORIENTATION INSTRUMENT BY THE REFERENCE PLANE
晶棒参考面X射线定向仪产品特点
⑴ 测量晶棒夹具的结构与功能介绍：
基准平台：此件固定在主机的台面板上，测量时做水平基准面，基准平台的右侧为定位面，左侧为夹紧装置，左侧的夹紧装置上有夹紧螺钉，设备配套的夹具在测量时放于基准平台上。
⑵ 测量〈A〉面：晶体主参考面<A>面定向：可测量晶棒直径为2、4、6英寸,<A>面的θ角：18.917°(18°55′00″)(或按客户需要做C向、R向)。
①仪器的校准：用标准晶棒校准仪器。晶向〈A〉的θ角：18.917° (18°55′00″)
②将装有晶棒的夹具，清理洁净后放到仪器的基准平台上，调整前后位置，使X光能够照射到晶棒的外圆柱面上，旋转基准平台左侧的夹紧螺钉，把紧。打开X射线光闸，使待测量晶棒在夹具内慢慢转动，寻测峰值。当μA表针为*状态时(即为zui大值时)，保证晶棒不动，夹紧晶棒。
③将夹具从定向仪下移出，转到磨床上磨削平面。
④自动升降测试。
Features
⑴ Construction and function of crystal clip
Benchmark platforms: it is fixed on the host machine panel, used for the horizontal platform when testing the sample.The right side of the base platform for locating surface, left platform for clamping .The clip has the screw clamping device.Please put the clip on the horizontal platform when begin to have a testing .
⑵Measuring the < A > direction : crystal main reference < A > flat orientation: it can measure crystal rods for 2, 4, 6 inch in diameter, <A> direction θ angle：18.917°(18 ° 55 '00 ") (or according to customers requirement ,use the C or R direction).
①The calibration of instruments: use a standard crystal rod calibration instrument. Crystal (A) θ Angle :18.917 ° (18 ° 55 ′00 ")
②After cleaning up the clip ,and put it on the horizontal platform for adjusting its position ,in order to enable the x-ray exposure on the outside skin of the cylinder crystal ,and fix the screw on the left of rotated horizontal.Open the X-ray shutter ,and let the crystal rotating slow to find the peak .When the μA meter find the best status (i.e the max.value) ,make sure the crystal being static,and fix it tightly.
③Unload the clip from the instrument ,and put it on the grinding plane of the grinding machine.
④Auto lifting test.
