Cutting Material Influence on the Quality of the Machined Surface

The aim of this paper is analyze of machined surface after grinding. A type of used abrasive significantly influences the machined surface quality. Studied was the influence of selected types of abrasives: 98A60K9 V, 99BA60K9 V, 49C60J9 V on the integrity of the machined surface selected materials. Four different steels: C45, C55, 54SiCr6 and 50CrV4, were used for analyses in two states (after hardening and delivered state). These steels are used in production significantly. Surface quality evaluation is performed using a contact roughness measurement and microstructure analysis. The results of this experiments show that there are differences between different abrasive machined surfaces.
