  • About the Editor
    • Details types of toolholders-collet chucks, hydraulic chucks, and polygonal holders-and their impact on runout and rigidity.
    • Explains selection criteria based on insert geometry, clamping force, and coolant delivery requirements.
    • Covers maintenance practices such as cleaning, inspection for wear, and proper torque settings for secure clamping.

Gao Lin is a tooling technologist whose Ph.D. in Mechanical Design underpins her work on low-vibration turning toolholders. She has developed clamping systems that significantly improve surface finish and tool life, and her comparative studies on modular versus monolithic holders influence industry standards. Gao collaborates with cutting-tool manufacturers to test novel geometries under dynamic loads and teaches advanced courses on tool-holder selection and balance analysis. Her current projects integrate sensor-embedded holders for in-process monitoring of cutting forces.
