Ensure a rigid, vibration-free link and absolute concentric truth between your machine spindle and workholding assemblies with industrial-grade Flanges for Lathe Chucks (adapter backing plates). Specifically designed to facilitate the mounting of standard 3-jaw and 4-jaw scroll chucks onto specialized spindle noses, these heavy-duty steel adapters feature pre-machined mounting profiles and integrated Camlock stud configurations. Precision-ground face and pilot surfaces distribute massive axial clamping force uniformly, neutralizing radial runout and spindle harmonics during heavy high-torque turning, aggressive roughing, and large-diameter machining.
