The brief of this job is to create a custom tooling package for mounting on a 4th axis rotary table. Holding a raw aluminium extruded blank, for finished milling in a single operation.
As our work holding must not get in the way of their tooling paths. Therefore, the challenge is incorporating milling clearances within the axial locator and jaws.
Our solution is a Northfield model 670, 2 Jaw Chuck with a custom set of internal grip jaws. Additionally, a custom axial locator that is finish ground and Electro Discharge Machined (EDM) allows for the required customer tooling clearances.
The design also incorporates a timing block. This ensures correct loading of the parts each time, and that they do not spin or change orientation during the milling operations.
Finally, the chuck is mounted to a 4th axis rotary table with a custom Northfield backported adapter plate. This allows air passageways to run though the rotary table into the rear side of our chuck for normal clamp and unclamp operations.
