It depends on the surface finish of the workpiece. For machined surface a magnetic base dial indicator is used. For rough or un-machined surfaces a surface gauge is used.
Ra 3.2 basically mean the surfaces must be machined to a tolerance of 3.2micro metres > Ra 3.2 would mean a standard finish on a lathe or miller ie not a deliberate finishing (slow speed) cut.
micro means 10 to the -6 inches so for example 32 microinches would be 0.000032 inch. With respect to surface finish it is basically a measure of the height of the "peaks and valleys" of the finish of a surface. There are different ways to measure this (RMS, etc.) but that is basically what it means. So for example a 125 microinch finish is a typical machined fnish for metals but a 32 is much better and would be called out where sealing surfaces may be needed.

Yes. The type of finish on the machined component's surface could be crucial to the quality of the type of coating or plating required.
Means to finish painting a drywall.

Finish grinding is used to achieve a precise surface finish and dimensional accuracy on machined parts. This process removes any surface irregularities left from earlier machining operations, ensuring optimal performance and aesthetics. It also enhances material properties, such as hardness and wear resistance, making the final product more durable. Overall, finish grinding is essential for meeting tight tolerances and improving the quality of the finished product.
