Question

Why there is a high amount of friction between polished surfaces?

Answer 1

We all know that polishing a surface reduces the friction.But if the Polish is too much then the friction increases instead of decreasing.
If the two surfaces of the same material are very smooth, the molecules and atoms of one surface get closer to the molecules and atoms of the other surface. As they get closer the molecular cohesive forces (attractive force)begin to take effect and the two surfaces will actually stick to each other.
If the surfaces are rough there are far fewer molecules that are close but the rough surface against another rough surface causes friction as in two bricks rubbing against eachother.
So if the Polish is too smooth the two surfaces gets binded together and friction increases.
You can try this with two polished surfaces of metal or glass.
