Concealed Hinge and Lock Pocket Machining for an Aluminum Door
A worked application example for mapping hinge recesses, lock pockets and handle openings on an aluminum door extrusion.
Application and evidence
Consider an aluminum door stile that needs a concealed hinge recess on one face and a lock pocket on the opposite side. This is an application example for planning a sample run.
Setup and process
Make a face-by-face feature list using the hardware drawings. Mark handing, pocket depths, corner radii and fastener positions. Evaluate whether a dedicated hinge station or a tool-changing configuration covers the required combination.
How to verify the sample
Dry-fit the actual hardware after deburring. Check flushness, spindle alignment and fastener clearance. Repeat on the mirrored stile and record which tool and fixture positions were used.

Before trialing a CNC hinge and lock hole drilling machine, identify which features need a drill and which require a milled pocket. Check that the cutter can reach both faces in the proposed setup.
