[0002] A spindle is a shaft that receives power from an engine or electric motor and transmits it to other components. A spindle is also called an "optical axis," which is short for "main optical axis." It is a diameter with symmetry in an optical system. For example, the spindle of a spherical mirror is a straight line that passes through the center of the mirror and is perpendicular to the mirror surface. The spindle of a lens or optical axis optical system is the line connecting the centers of the lens surfaces. When performing pressure testing, the spindle needs to be clamped and fixed, which requires the use of a spindle pressure testing and fixing fixture.
