What Is Grinding Machine?- Definition, and Types

Grinding is used to finish workpieces that must show high surface quality (e.g., low surface roughness) and high accuracy of shape and dimension. As the accuracy in dimensions in grinding is of the order of 0.000025 mm, in most applications, it tends to be a finishing operation and removes comparatively little metal, about 0.25 to 0.50 mm depth.

5 Grinding Considerations for Improving Surface Finish

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.
