Correct option is C
Honing is a precision machining process used for
superfinishing bores and achieving high dimensional accuracy and surface finish.
It uses
abrasive stones or sticks to remove small amounts of material from the bore's surface.
It is particularly effective for
ferrous metals, as it enhances the surface quality and minimizes friction in applications like engine cylinders or hydraulic components.
Filing: A manual process used for shaping or smoothing surfaces, not suitable for precision finishing of bores.
Drilling: Used to create or enlarge holes, but it does not provide the precision or finish required for superfinishing.
Grinding: Used for general precision machining and finishing, but honing is more specialized for internal surfaces of bores.
