Sander-polishing machines
Introduction
The machine that, by mounting sandpaper or cloth, allows you to carry out the sanding process on a surface, generally wood, although it can be used to sand different materials and is called a semi-automatic tool.
There are manual sanders and stationary sanders, which in turn can be belt, orbital or contact sanders.
In joinery and carpentry they are usually used for roughing and sanding surfaces to be worked on and for fine finishing. Given the latter, in many cases manual sanding continues to prevail, since it allows you to be in direct contact with the piece and use touch to recognize the quality of the work.
