Crystal grinding aid

Technical Field

Background

Crystal orientation is a crystal processing technique that generally requires grinding out this face after the crystal is oriented to better cut in subsequent processing, but the orientation face is adjusted by slicing mainly directly, except for grinding the crystal, but slicing operation gives a better orientation of the cut face, but relatively more crystals are wasted than grinding if multiple adjustments of angles are needed, and the main crystal of the slice is fixed on a cutter, so the adjustment of rotation angle in operation is limited, so most highly skilled researchers prefer to determine crystal faces by grinding the crystal. However, the orientation by the grinding requires a hand to adjust the angle, which requires a great skill, may be slightly offset by a few degrees, and it is difficult to grind a large flat plane by the grinding by hand, so an auxiliary grinding device is required to fix the angle.
