  • About the Editor
    • Introduces the principles of through-feed, in-feed, and end-feed centerless grinding operations for different part geometries.
    • Details the functions of the regulating wheel, grinding wheel, and workrest blade in maintaining part control.
    • Highlights process parameters-such as wheel speed differential and blade angle-that affect part straightness and size accuracy.

Joseph Kamau is a specialist in centerless grinding operations with extensive experience in mass-production settings. He holds a Ph.D. in Manufacturing Systems and has led process improvement teams that increased yield and reduced scrap rates in bearing and pin production. Joseph's publications address the optimization of workrest and regulating wheel geometries to achieve consistent roundness without fixturing. He has designed training modules for operators and engineers on setup, in-process inspection, and quick change-over techniques. As a consultant, Joseph advises global OEMs on retrofitting legacy lines with modern centerless grinders. His current studies focus on integrating vision systems for automated part loading and defect detection.
