CUTTING PLATE HAVING MARKS INDICATING ORIENTATION OF OPENING AND METHOD OF ITS MANUFACTURING Russian patent published in 2017 - IPC B23C5/10 B23C5/20 B23B27/16 

FIELD: process engineering.

SUBSTANCE: group of inventions relates to processing materials with cutting and can be used in cutting tools with removable cutting inserts, as well as in manufacturing them. The cutting plate comprises the first surface, the second surface, the peripheral surface extending there between, and the screw release axis passing through the cutting plate center and parallel to the first and second surfaces. Between the first and second surfaces an opening is made, the cross section of at least portion thereof is performed perpendicular to the opening axis and has an oval shape. On at least one of the first and second surfaces a mark is made, indicating the orientation of the oval cross-sectional shape of at least part of the cutting plate opening and the orientation of the release axis of said screw. Said mark can be performed in various ways.

EFFECT: easy replacement of a cutting plate is provided.
