Abstract (en)
[origin: EP0673714A1] The technique includes finishing the holes (2) formed in a plate (1), the holes being intended to receive a series of parallel tubes (3) in a regular pattern. Each hole is larger than the tube to be supported, but includes at least three contact surfaces (4) which project inwards in order to support the tube. In order to smooth and bevel the edges of the holes, partic. the contact surfaces, a rotary brush is moved over the plate surface. The brush moves along a series of parallel lines (5a,5b,5c), each of which forms a tangent to a selection of contact surfaces. By means of a sequence of passes over the plate, all surfaces may be smoothed.
