Evaluating a JR-2200 Hinge Milling Setup

Identify what three-sided means on your part

Bring a section drawing that marks each hinge recess, fixing hole and reference face. Ask the operator to show how each face is presented to the tool and when the part is moved. The product name describes an application, while the quoted fixture and tool approach establish the actual work envelope.

Choose a sample with difficult clearance

Use the deepest recess nearest a clamp and the shortest stile the fixture must hold. Verify holder clearance and check that the surface pads protect the finish. If work on two faces uses a second setup, measure their relationship from the same finished datum.

Approve the assembled result

Run the actual hinge and screws in a complete sample joint. Repeat on a mirrored part and after a profile change. Record the setup and which operations still require a separate station. Ask for that exact arrangement in the quotation and retain the accepted sample for commissioning.

What to record before production release

Keep a separate line for each recess, mounting hole and operation after reorientation. Note whether the demonstration used an alternate fixture or head. Use those records to confirm what is actually included in the JR-2200 configuration offered.
