Application at a glance ### Typical component families | Shafts, bushings, spacers | Titanium Gr5, stainless, aluminum | Aerospace screws (visserie) | Titanium, alloy steel ### Typical supply parameters | Batch range | 10–10,000 pcs per family | Tolerance scheme | DIN ISO 2768-mK, drawing fits | Documentation | EN 10204 3.1, First Article Inspection ## Parameter Quick Reference | Parameter | Specification | Component families | axes / bagues / entretoises (shafts, bushings, spacers); visserie aéronautique (aerospace screws) | Typical materials | titanium Gr5, stainless steel, aluminum; titanium, alloy steel | Machining processes | turn-milling; cold forging / turning | Typical batch sizes | 10–10,000 pcs per family | Default tolerance scheme | DIN ISO 2768-mK, drawing fits | Material certificates | EN 10204 3.1 | Inspection requirement | First Article Inspection | Quotation and sample lead time | quotation within 48 hours; first samples in 7–15 days ## Industry scenario: the Tier2 subcontract layer Aerospace certification (EN 9100) is the entry ticket for flight-critical parts, and not every program needs it: equipment manufacturers (équipementiers) routinely outsource non-flight-critical machined components — shafts, bushings, spacers, screws — to qualified Tier2 subcontractors with full traceability and documentation. Our position in this vertical is explicit: we supply the Tier2 subcontract layer for non-flight-critical components with EN 10204 3.1 certificates and First Article Inspection. Certification scope is stated honestly, and customers confirm the applicable requirements per program. ## Typical component families and processes | Component (FR / EN) | Typical material | Process | Typical batch | axes / bagues / entretoises (shafts, bushings, spacers) | titanium Gr5, stainless steel, aluminum | turn-milling | 10–500 pcs | visserie aéronautique (aerospace screws) | titanium, alloy steel | cold forging / turning | 1,000–10,000 pcs Titanium turning and aerospace screw production are established processes; batches in this vertical are typically smaller and documentation-heavier than general industry. ## Workflow: drawing, sample approval and recurring series The standard flow: drawing review and quotation within 48 hours, first samples in 7–15 days, first article inspection and approval, then series production against the approved reference. Tooling, program revisions and inspection records are kept on file so that call-offs remain consistent with the approved first article. Engineering changes — material substitutions, tolerance updates, plating or packaging changes — are handled as controlled changes against the same records. ## Quality and documentation DIN ISO 2768-mK applies as the default tolerance scheme for unspecified dimensions. EN 10204 3.1 inspection certificates are standard for metallic parts, First Article Inspection supports the approval step, and RoHS/REACH declarations are available where required. Plating, cleanliness and packaging requirements are confirmed per drawing. ## FAQ Are you EN 9100 certified?No — our position is the Tier2 subcontract layer for non-flight-critical components, supplied with EN 10204 3.1 certificates and First Article Inspection. Certification requirements are confirmed per program with the customer. Can you machine titanium Gr5?Yes — titanium turning and turn-milling are established processes; cutting parameters and dimensional strategy are controlled per part family. What batch sizes are typical for aerospace components?10–500 pieces for machined shafts and bushings; screws and visserie families from 1,000 pieces. Which documentation accompanies an aerospace order?EN 10204 3.1 material certificates, First Article Inspection and full traceability from bar to shipped part. ### Related Materials · Related Services · Related Case Studies [Related Materials: Titanium ](https://www.sinbo-machining.com/products/materials/titanium/)[· Stainless Steel ](https://www.sinbo-machining.com/products/materials/stainless-steel/)[Related Services: Cnc Machining ](https://www.sinbo-machining.com/services/cnc-machining/)[Related Case Studies: Aerospace Structural Bracket ](https://www.sinbo-machining.com/case/aerospace-structural-bracket/)[· Medical Instrument Parts ](https://www.sinbo-machining.com/case/medical-instrument-parts/)This page describes a representative application scenario for the aerospace equipment supply industry, compiled from typical requirements of this vertical.
