To this end, there is provided a linishing tool for
reconditioning a camshaft integral bearing surface of a cylinder head
including an elongate body (1) having an outer surface (2), at least a
portion of the outer surface of the body being a linishing surface
(3), and at least one handle (5) provided at an end of the body,
the body having at least one cylindral section (8) with a lateral
cross section having a diameter corresponding to the required
bearing diameter of the camshaft integral bearing surface. The
metal finishing process of "linishing" involves the use of a surface
covered by fine particles of hard material which acts as an
abrasive for the removal of matter by scratching and grinding. This is
distinguished from line borers, reamers and files which all use
a cutting action to remove material.
Outil abrasif de surfaçage destiné au reconditionnement de la surface des paliers d'un arbre à came solidaires dans une culasse. L'outil comprend un corps (1) de forme allongée présentant une surface externe (2) dont au moins une partie constitue la surface abrasive (3) et, au minimum un manche (5) à une extrémité de ce corps, ce dernier comportant au moins une partie cylindrique (8) dont la section transversale latérale présente un diamètre correspondant au diamètre de palier nécessaire défini par la surface des paliers solidaires de l'arbre à came. Le procédé de finition métallurgique constitué par le "surfaçage" met en oeuvre une surface couverte de fines particules d'un matériau dur agissant comme abrasif enlevant de la matière par abrasion et meulage. Ce procédé se distingue du limage, du brochage et de l'alésage en ligne par le fait que ces derniers nécessitent tous un effet de coupe pour l'enlèvement de matière.
