METHOD OF THE ABRASIVE PROCESSING Russian patent published in 1995 - IPC

FIELD: mechanical engineering. SUBSTANCE: article 1 is placed between two ring-shaped face laps 3 and 4 at the angle approximating 15° to the lap radius. The laps are given the relative displacements. The article is installed into the centers movable in the vertical direction. The center axis (the axis of the article rotation) is shifted fro, the lower surface of companion 2 towards the upper lap by the value of d/2+/3-5/δ, where d is the maximum size of the abrasive grain, d- is the preset diameter of the article. The upper lap in the course of processing is lowered by the value of h=D-d-Δd, where D- is the actual diameter of the article, mm, Δd ≥ /3 ... 5/δ. After that the position of centers (the axis of the article rotation) is fixed relatively to the lower lap. Then the upper lap is lowered in the course of the further processing by the value of Dd. EFFECT: enhanced accuracy of processing. 3 dwg
