Chatter marks on hardwood floors.
These marks are often referred to as chatter marks.
Rippling in a wood floor is called chatter if the ripples are less than 1 1 2 inches apart and waves if the ripples are more than 1 1 2 inches apart.
The wave is more likely an equipment issue.
Chatter for the most part is not severe and for the most part is a vibration issue.
Poor seams on the abrasive belt drive belts and fan belts worn pulleys and bad bearings in the fan housing also can cause chatter and imperfections in the floor.
Wave is a repeat of the first imperfection that runs repeatedly over the floor and is typically more than 1 1 2 inches apart.

First of all if the floor is already stained it will require different sanding procedures than a floor that is unfinished.
Chatter can be caused by a loose sub floor just as an example.
Other potential causes are belts with a flat spot drums with a flat spot bad bearings a worn upper roller and more.
