Functions:
This equipment professionally used for orientation of crystal bar reference surface when it is processed, it is a matching device for latter procedure of ex-circle barreling tool, operator can put ex-circle barreling tool and rubbed crystal bar on this angular instrument for orientation purpose, then rub the reference surface on plane grinding machine. Because its orientation angle is fixed, customer can select different crystal angle according to crystal material, for example: Angle of sapphire A, R surface; silicon, gallium arsenide arsenide, germanium(110) and others.(User can select crystal orientation angle when purchasing)
Features:
One of advantages for this instrument is high measuring accuracy. Orientation of one set instrument can satisfied with multiple sets of units’ plane grinder using. For standard configuration will including each of 2,4inch clamp. ( User can select clamp dimension when purchasing)
Methods:
Put the crystal bar which rubbed by barreling tool in surface of V type groove clamp, then put it on working table, slowly move the orientation head down until touch the crystal bar, open radiation optical shutter to measure its crystal orientation, then slowly rotates crystal bar to find its reference surface direction, repeat for several times to find max angle value; then clamp tightly, put whole V type groove clamp on plane grinding machine to rub reference surface.
