Just a corruption of "pulitura".
However I have seen it used as a translation of "buffing" or "polishing", so I would recommend caution: I would search for/ ask the customer for a description/explanation of the process. Then it's easy to decide.

Please, see this link.

Brushing and polishing

It is carried out with different types of brushes applied to cleaning machines, or used by hand. They may be made with vegetable fibre or metal wires (brass, stainless steel, nickel, etc.).

After the sanding, in order to prepare the ferrous material for glossy nickel plating, or to facilitate the reviving of matt-plated metals, it is very useful to proceed to brushing with vegetable fibre brush discs soaked with fine emery and mineral oil, or olein. The most commonly used vegetable fibre brushes are those made with tampico (fig. 179), a type of grass grown in Mexico. The aim of the treatment with tampico is to even the streaks left by previous sanders, directing them towards one way. The resulting uniformity facilitates subsequent polishing treatments. There are ring-shaped tampico brushes (fig. 179) as well as continuous spiral brushes (fig. 179 b), also known as strip brushes; the latter have a compact and uniform brushing surface.

Different satin and matt effects can be obtained by brushing the surfaces in certain directions with variously lubricated metal wire discs, with or without abrasives. A given surface appearance depends on the thickness of the wires
