Rollomatic has announced that it successfully produced a surface finish of Ra 48 nanometers (0.048 micrometer) on a primary relief of a profile insert in PCBN material.
The tests were performed on the LaserSmart LS510 cutting and ablation machine with five interpolating CNC axes. A “super-mirror” finish is generally considered to be around 100 nanometers, a benchmark that the achieved finish cut in half.
The tests were performed at the Rollomatic showroom facility in Mundelein, IL. Rollomatic says that feedrates or cycle times were not impacted. “The process ensured that the integrity of the edge quality was fully maintained without compromise,” Rollomatic says.
Verification and measurement were carried out with a Bruker-Alicona EdgeMaster Optical 3-Dimensional Metrology Unit.
