Abstract

1. A cylindrical planing assembly, particularly for a surfacing and thicknessing machine, comprising, mounted at regular intervals around the periphery of a rotor (1), at least two planing machine knives (5), each planing machine knife being fixed by means of at least two dowel pins (10) on a strip-like holder, its cutting edge or effective cutting edge (6, 7) being exactly orientated in relation to the rotor and being at an exactly fixed distance from the fitting bores of the knives, characterised in that each holder is supported accurately in a longitudinal groove (2, 3) in the rotor (1) which is associated accurately with the geometrical axis (8) of the rotor (1) in that by its end portions (17, 18) it is supported by its supporting surface (15) which is towards the bottom (16) of the groove on a step (19) which projects somewhat outwardly beyond the groove bottom, an imaginary plane extending through the supporting surfaces (25) of the two steps (19) of each longitudinal groove (2, 3) being remote from the geometrical axis (8) of the cylindrical planing unit by an amount which is maintained with a high degree of accuracy.
