The roughness peaks are levelled and the roughness reduced. This creates a smooth and resistant surface. Impressive advantages ■ Smoothing of extremely hard materials up to 65 HRC with surface quality Rz < 1 μm possible. ■ Simple and flexible application. 29 Different shank sizes using adapters. ■ 8 possibilities for using diamond tip. Easy change of position by means of indexing. Standard application values The technology values for the burnishing process are based on the finishing process, which was used to pre-machine the workpiece. ○ ISO code N N N P P P P P H H H M M S K ​ ​ ​ ap mm 0.005 – 0.02 0.006 – 0.04 0.01 – 0.08 0.01 – 0.1 0.01 – 0.1 0.05 – 0.2 0.005 – 0.02 ● ● f mm/rev 0.03 – 0.1 0.02 – 0.06 0.02 – 0.1 0.02 – 0.06 0.02 – 0.06 0.05 – 0.1 0.02 – 0.06 ● ● VC m/min 120 – 140 110 – 140 100 – 130 100 – 130 100 – 130 80 – 120 100 – 130 ● ● 910
