Having been in the machining industry for many years, you must be no stranger to tool failure.
Flank wear
Flank wear refers to the abrasion loss of the flank of the tool immediately below the cutting edge. The carbide particles in the workpiece material or the work-hardened material rubs against the blade. Small pieces of the coating peel off and the blade rubs. The cobalt element in the blade is finally separated from the crystal lattice, reducing the adhesion of the cemented carbide and thus peeling off.
Crumble
Flank chipping
Rake area edge
Certain workpiece materials may create a rake area between the chip and the cutting edge. When the continuous lamination of the workpiece material is connected to the cutting edge, built-up edge will occur. The built-up tumor is a dynamic structure. During the cutting process, the cut surface of the built-up edge continuously peeled off and reattached.
PCD tools offer excellent hardness and wear resistance for machining difficult materials, but grinding them poses unique challenges. This article explores common issues such as chipping, high surface roughness, dimensional deviations, burning, and grinding wheel wear. Learn practical solutions to optimize grinding parameters, wheel selection, and machine accuracy to improve tool life and reduce costs.
