Embodiment

[0025] A cutting insert with multiple combinations of cutting edges according to the present invention includes multiple cutting edges composed of a rake face and a flank face; the multiple cutting edges are respectively subjected to corresponding passivation treatment, and have certain passivation value; among the multiple cutting edges, at least two cutting edges have different passivation values; and the difference between the maximum passivation value and the minimum passivation value is in the range of 10 μm to 100 μm; The cutting edges having different passivation values ​​constitute different cutting edges of the cutting insert.

[0026] Further, the range of the difference between the maximum passivation value and the minimum passivation value is between 20 μm and 80 μm.

[0027] Further, the range of the difference between the maximum passivation value and the minimum passivation value is between 30 μm and 50 μm.

[0028] The rake faces corresponding to each of the c...

Abstract

The invention discloses a cutting blade with multiple cutting edge combinations. The cutting blade comprises multiple cutting edges composed of front tool faces and rear tool faces. Corresponding passivating treatment is performed on the multiple cutting edges, and the multiple cutting edges have determined passivating values; the passivating values of at least two cutting edges are different among the multiple cutting edges; the value of difference between the maximum passivating value and the minimum passivating value ranges from 10 microns to 100 microns; different cutting edges of the cutting blade are composed of the cutting edges of which the passivating values are different. By performing different settings on the passivating values of the cutting edges, the corner radii of the front tool faces corresponding to the cutting edges, the geometrical parameters of chip breaker grooves corresponding to the cutting edges, the included angles between the front tool faces and the rear tool faces corresponding to the cutting edges and the like, multiple different cutting edges can be formed; in this way, the cutting blade has the dual functions of rough machining and finish machining, efficient combined machining can be achieved, and the purposes of prolonging the service life of a tool and improving production efficiency can be achieved.

Description

technical field [0001] The invention relates to the field of metal cutting tools, in particular to a cutting insert with multiple edge combinations. Background technique [0002] The passivation of the blade is generally arc-shaped, and the radius of curvature is the same everywhere in the arc, and the strength of the blade is also the same. [0003] The passivation of the cutting edge can improve the microscopic defects of the cutting edge, and achieve the purpose of smoothness, sharpness, firmness and durability. However, the sharper the cutting edge is not necessarily the better, nor is the blunt the better. Determining different passivation values ​​for different processing conditions can effectively improve the strength of the cutting edge and the life of the tool. [0004] When the cutting workpiece is a high-strength material or has a strong impact on the cutting edge, the excessively sharp cutting edge is easy to chip during the cutting process, so a larger edge pas...
