 | Top Jaws for Northfield Chucks
Top jaws are a critical part of a precision workholding system. The same attention must be paid to jaw design and manufacture as to chuck machine performance if maximum accuracy is to be achieved at the workpiece. Northfield‘s experienced workholding engineers and specialized manufacturing facilities provide a unique capability for the design and manufacture of custom jaws.
Based on customer drawings or workpieces, we design jaws to hold the most intricate or fragile parts. The appropriate material is used - from hardened and ground tool steel through aluminum to Delrin plastic and serrated diamond points. Jaws are created for external, thin-wall/rigid, over-the-shoulder, and hundreds of other unique solutions to exactly meet each workholding requirement to bring gauge block accuracy to your production pieces. |
