Island Park, New York – Northfield Precision Instrument Corp., a designer and manufacturer of precision workholding chucks, specializes in developing custom solutions for difficult problems.
In this particular case, Northfield designed a special version of its Model 450 4'' diameter air chuck with special hardened and ground jaws to grip the OD of a precision split collet. The collet is specially hardened and ground to locate on a 0.8683" part diameter. The collet has an OD of approximately 1.800" to clear the flange. The collets are made of alloy steel with the ID and OD ground at the same time to insure tight tolerance run out.
Northfield Precision Instrument designs and manufactures air chucks for any lathe, boring machine, grinder or VMC. Models include through-hole, high-speed, and quick-change. Chucks are available in SAE or metric, in sizes from 3" (76mm) to 18" (457mm). Accuracies of 0.001" to 0.00001" are guaranteed. Custom workholding chucks and jaws are available and free engineering assistance is offered.
