5 Grinding Considerations for Improving Surface Finish

5 Grinding Considerations for Improving Surface Finish

Aug 20, 2021 If the goal is to improve the current surface finish from 20 microinch Ra to 17 microinch Ra, then simply increasing the wheel speed and/or reducing the feed rate slightly might be sufficient. However, if a finer surface finish is required, then these five factors should be addressed. 1. Grinding Operational Parameters.

Influence of grinding parameters on Inconel 625 surface

Influence of grinding parameters on Inconel 625 surface

Jul 01, 2020 Surface integrity was assessed in terms of surface roughness (Ra and Rz), observations of SEM images and microhardness. The results showed that Inconel 625 is highly susceptible to work hardening during grinding. The grinding wheel speed (v s) was the parameter of greatest effect and the best results were obtained when v s =15 m/s.

Surface roughness is defined as a group of irregular waves in the surface, measured in micrometers (μm). The roughness data obtained by measurement can be manipulated to determine the roughness parameter. There are many different roughness parameters in use, but Ra is the most common. Other common parameters include Rz, Rq, and Rsk.
