Estimating the term…
The present invention concerns a method for sharpening a worn removable machining tip (3) and the corresponding sharpened tip. The tip having a first cutting edge (7) damaged after a first use (u1), said tip having, in the state prior to the use of same, specific dimensional and geometrical parameters within a defined tolerance range and said first undamaged cutting edge (7) having a defined sharpness, the method involves sharpening the cutting face (9) by removing material from said cutting face on said first damaged edge (7), in order to make said tip (3) match said specific dimensional and geometrical parameters within said defined tolerance range, having a second cutting edge (7′) of said defined sharpness.
A method for sharpening a worn removable machining insert (3) having a first cutting edge (7) damaged after a first use (u1), said insert having, in the state prior to its use, specific dimensional and geometric parameters within a defined tolerance range and said first undamaged cutting edge (7) of defined sharpness, characterized in that the sharpening is carried out on the rake face (9) by removing material from said rake face on said first damaged edge (7), a sharpening line (A1) being inclined by a nonzero angle with respect to the rake face (9), in order to make said insert (3) correspond to said specific dimensional and geometric parameters within said defined tolerance range, while having a second cutting edge (7′) of said defined sharpness.
