The UBL Centralizing type chucks employ a common clamping method, using the clamping part as a concentricity reference and the stop face as an end face reference. They are capable of clamping such difficult-to-clamp work-pieces as tapered (20 degree max.) sufaces of casting of forging products, holding them tightly even under heavy dusties, 2 jaws type and 3 jaws type are available and every UBL chucks can correspond to both I.D. or O.D. clamping which can be easily converted from each oter. We are liable to design and produce chucks according to your request such as troublesome body modification and every top tooling. UBL chucks include a wide variety if designs, such as carbide insert jaws and special shaped jaws for material operation wide type jaws for thin-walled work-pieces, high-tension aluminum jaws for high-speed rotation, an combination jaws and quick change jaws for small-lot production. The Centralizing type chucks is suitable for using on a flat surface due to the type of the jaw cannot move while the work-pieces surface roughness may cause the tilt.
