The support finger has a spring that pushes the bar a bit towards the grinding wheel. You set the spring force by (you guessed it!) measuring the change in the diameter of the bar between the ends and the middle. Hence the need for a simple and reliable way of measuring the diameter along this bar, and similar ones.

Surface Finish. Surface grinding is highly effective in producing a flat, smooth surface that requires minimal additional surface finishing. Cylindrical grinding, on the other hand, can achieve an extremely high-quality surface finish with minimal waviness, making it ideal for components that need to be highly polished, such as mirrors or lenses.
