CHENGSHUO | ENGINEERING CONCEPT REVIEW Reference concept: Ceramic ferrule holder Page: https://chengshuoprecision.com/components/bushings-and-rings/ceramic-ferrule-holder/ Our component / drawing revision: [ ] Assembly and mating interfaces: [ ] Please review: 1. Metal-holder and ceramic-ferrule drawings with mounting reference 2. Material, final finish, retention method and cleanliness requirements 3. Quantities, dimensional evidence and separate optical-assembly approval scope Sample acceptance to agree: 1. Receiving bore: Specify usable diameter, depth and lead-in against the ceramic part. 2. Axial stop: Identify shoulder location and allowed contact condition. 3. Mounting reference: Relate bore to external pilot or mounting face as required. 4. Assembly cleanliness: Define internal edge condition, cleaning and protected packing. Material grade / finish: [ ] Sample / production quantities: [ ] Target timing / delivery destination: [ ] AI-generated engineering concept, not a production photograph or completed delivery. Feasibility, process route and acceptance criteria require review of our actual drawing.
