Polycrystalline diamond (PCD)- and chemical vapor deposition (CVD)-coated diamond carbide cutting tools are a great option when machining highly abrasive materials because the coating significantly increases tool life. However, a thick-film coating dulls the cutting edge and thin‐film coatings often wear prematurely.
The 5-axis LaserSmart 510 laser-cutting and ablation machine developed by Rollomatic Inc. (Mundelein, IL) probes the surface of the coated cutting edge to detect exact shape and position and then removes just enough of the coating to make the cutting edge sharp. Only a predetermined amount of the coating, just around the cutting edge, is removed.
The fine-laser cutting process achieves a superfine edge with a surface finish that’s unachievable by EDM, EDG (electro-discharge), or grinding. Conventional grinding with diamond wheels will invariably “pull out” entire PCD crystals, but laser cutting slices through the crystal and leaves a portion of the crystal in the matrix.
