Abstract

The configuration of a lathe's chuck during machining has a significant impact on its capability (horsepower and accuracy potential). Due to centrifugal force, most jaw chucks lose gripping force as spindle speed rises, undermining the lathe's ability to extract material and cycle time and production costs. In this document, a pneumatically controlled 3-jaw self-centering chuck is constructed from a cold work tool steel AISI A2 for machining an aluminum work component with a diameter of 30 to 110mm. It is compatible with a traditional lathe CD6250C. To provide the necessary jaw travels, a self-contained air reservoir and actuating cylinder with pneumatic piston are provided within the chuck body itself. A simple manual push button 3 port 2 position directional control valve controls the direction of flow of pressurized air. Both of the cutting forces involved, as well as the centrifugal impact of both the master and top jaws, are taken into account when deciding the necessary amount of gripping forces and working pressure. After that, the pneumatic chuck is modelled using commercial Solid Works 2013 software, and many component and assembly drawings are made. After all, the constructed pneumatic self-centering chuck and its components are made using cost-effective manufacturing methods.
