New 3-Jaw 20” Scroll Chucks
Buck Chuck announced the release of their new 20” ATSC scroll chuck to meet the demand for larger chucking options. This manual, self-centering scroll chuck is designed with a high-quality forged steel body construction to provide precision gripping, suitable for high-production runs. The Ajust-Tru design, with integral clearance between the chuck body and the mounting adapter, allows for the use of adjusting screws for fine-tuning the concentricity of the chuck to the machine tool’s spindle, providing ±.0005” TIR repeatability. To further optimize performance, the scroll plate, jaws and pinions are hardened and ground for precision and long wear.
The family of Buck ATSC manual scroll chucks range in size from 4” to 20” diameters with through-hole sizes from 1.04” up to 7.48”. Additionally, most chuck sizes are available in model variations with either 3-jaw or 6-jaw designs. The new 20” ATSC chuck is a 3-jaw style and ships complete with master jaws and hardened, reversible top jaws for both ID and OD gripping, a spring-loaded T-wrench, an Allen wrench and mounting bolts. A variety of mounting plates are stocked for mounting the chuck to common machine spindles including American Standard styles A1, A2 and D1 camlock style. Other mounting plates can be manufactured on application.
