Thin-Wall Aluminum Cavity for Medical Instruments
Thin-wall aluminum cavity and matching bushings, judged on wall consistency and appearance.
Requirement
The instrument needs a lightweight cavity with 1.5 mm walls. The outer surface is visible, so tool marks and distortion are not acceptable. Matching bushings must assemble smoothly without play.
Our approach
Blanks are stress-relieved first, then roughed, semi-finished symmetrically and finished with light cuts. The outer surface runs a high-speed finishing path to limit tool marks. Bushing ID and OD are turned in one clamping, with fit confirmed against the customer gauges.
Delivery and inspection
First batch of 10 pieces each, with wall thickness and critical dimension records; 100% visual inspection on cosmetic faces.
Project summary
Assembly is tight with no play, and the cosmetic surfaces were accepted without secondary polishing. The process route is now standard for later models.
