The main differences between ground stainless steel rod and polished rod lie in the processing technology, 

surface treatment, application scenarios, and price.

Processing Technology and Surface Treatment:

Ground rod: Mechanically ground, it achieves a smoother surface and precise tolerances, 

making it suitable for applications with high dimensional and geometric tolerance requirements. 

During the grinding process, the surface of the ground rod is ground to remove the oxide scale, 

achieving a higher finish and precision.

Purpose-polished rod: Typically produced through cold drawing, fine grinding, or polishing, 

it has a brighter surface and is suitable for applications requiring a smooth surface but less stringent dimensional and geometric tolerance requirements.

The surface treatment of polished rod primarily increases the surface gloss through chemical methods,

 without mechanical grinding.

Applications:

Ground rod: Primarily used in applications requiring high-precision machining, 

such as precision machinery and instrumentation, as it offers higher dimensional and geometric tolerance accuracy.

Pure-polished rod: Suitable for applications requiring a high surface finish, such as household goods, 

automotive parts, and medical devices, due to its excellent corrosion and heat resistance.

Price: Because ground rods require more complex processing and require higher precision and surface finish, 

they are generally more expensive than polished rods.

In summary, the main differences between stainless steel ground rods and polished rods lie in their processing, 

surface finish, application scenarios, and price. Choosing which rod material to use depends on specific application requirements and budget considerations.
