The machine has a cutting head including a vertical cutting module (A) that cooperates either with a vertical cutting module (B) or with feed module for carrying out cutting operation. A spur tool (1) is formed of circular disk whose periphery has a peripheral cutting edge. A plane of an upper surface of the tool extends under a plane of a lower surface a cutting tool. External diameter of the tool is less than a diameter of cutting tool that is disengaged from active units intervening the operation, where a difference between the diameters is equal to defined value of 2 microns. |
