| Zusammenfassung | Drills with a diameter of less than 1.2 mm are used for a number of different applications in manufacturing electronic parts. In industrial practice they are in a machine tool together with more than 200 single drills of different diameter. For some machines it is not possible to change the number of turns for the individual diameters. So the cutting conditions are also different in these cases. The drills were coated by using different PVD techniques and various coating materials. For the elevation of the performance of the coated and uncoated drills, an industrial board package was used which initiates adhesive and abrasive wear. For the described tribology system, PVD coatings achieve a higher lifetime compared with the uncoated drills. |
