Side Loading Chuck


Category: Tags: ,


This tooling was developed in conjunction with our customer to allow side-loading of their part into the very center of the small cylindrical insert pads (which have been wire-cut for accuracy) at the top of the photo. These insert pads are changeable (and held on-center to the chuck’s OD within their subjaws as shown) to accommodate different sizes of the customer’s part. The subjaws themselves have a large milled pocket, to clear their part. This is a grinding application where Northfield Precision met the required accuracy / repeatability of .0001” TIR or better when mounted on the customer’s spindle.
