<p>The polishing equipment produces different contours, convex or concave, on rough-cut surfaces, without repeated operations. A coordinated guidance and interaction programme is followed for the surface to be polished and the grindstones of the polishing heads. There can be a fixed or mobile guide on the frame, securing the sections of contour in position on first alignment when loading on the truck capstan. The latter can have suction cups.</p> |
