Buck Chuck has added to its available lineup of manual, self-centering Ajust-Tru Scroll Chuck (ATSC) to include 22 variations of sizes and styles with the addition of two 15"-diameter configurations. The units feature a solid steel body, and their level of precision and repeatability makes these chucks well suited for lathes and turning center applications as well as for integration with machining center workholding and other processing systems requiring rotary-type fixturing, the company says.

The company also offers 4", 5", 6", 8", 10" and 12" diameter sizes, with through-the-spindle diameters from 1.04" to as much as 5.51" for the larger units. The selection of chuck sizes is bolstered with the offering of model variations with either three-jaw or six-jaw designs and the option of master jaw with top-mounting reversible jaws, or with inside/outside solid jaw-style tooling.

The Ajust-Tru design, with integral clearance between the chuck body and the mounting adapter, allows for the use of adjusting screws that can be fine-tuned to zero in the concentricity of the chuck to the machine tool's spindle, providing ± 0.0005" TIR repeatability with duplicate parts.
