Abstract :In this study, the previously designed SAE 4140 and 50CrMo4 material standard lathe collets was found to be inadequate in terms of service life and the new 50CrMo4 material standard collet was designed. Fatigue tester was designed and manufactured for fatigue analysis to determine the life of the collet. When designing fatigue tester, 2.2 kW Volt motor and Siemens control are used for field usage conditions. Analyzes were made with ANSYS software then the collets were tested under 25 bar hydraulic pressure and the results were compared. As a result of analysis and fatigue tests, fatigue behaviors of collets were compared.
