Pockets, angled faces, thin ribs, and multi-sided details, with setups planned around the datums.
Turning & Turn-Mill
Shafts, fittings, bushings, and rotational parts with milled or cross-drilled features.
Rectificado de precisión
Selected surfaces requiring controlled size, form, or finish after review of material and geometry.
Electroerosión por hilo
Fine slots and complex profiles in conductive materials, with surface integrity reviewed for the application.
Fabricación de chapas metálicas
Brackets, panels, covers, and formed components with drawing-defined bend and assembly requirements.
Acabado de superficies
Substrate-compatible treatments matched to corrosion, wear, electrical contact, and masking requirements.
Tolerances Follow the Specification
- Drawing Dimensions and Datums
- Explicit dimensions, GD&T, datum systems, and acceptance notes take priority.
- General Tolerances and Fits
- Use the drawing’s stated system; ISO 2768-1 or ISO 286 applies only when specified and agreed.
- Geometric Controls
- Follow the specified ISO 1101 or ASME Y14.5 basis and revision; the systems are not interchangeable by default.
- Selected Critical Features
- Features down to ±0.005 mm require individual process and measurement review. This is not a blanket part tolerance.
Materiales para componentes aeroespaciales
Match the specified grade and condition to weight, load, fatigue, temperature, corrosion exposure, and finishing requirements.
| Material | Grade Examples | Selection and Use |
|---|---|---|
| Aluminio | 2024, 6061, 7075 | Structures, brackets, housings, and heat sinks; alloy and temper follow the drawing. |
| Titanio | 2.º curso, 5.º curso | Corrosion-resistant components; Grade 5 is commonly considered for higher strength requirements. |
| Acero inoxidable | 304, 316, 17-4 PH | Fittings, housings, and shafts; confirm corrosion duty and heat-treatment condition. |
| Acero aleado y acero para herramientas | 4140, 4340; specified tooling grades | High-load mechanical interfaces and tooling; strength depends on the required condition. |
| Aleaciones de níquel | Inconel 625, Inconel 718 | Heat- and corrosion-resistant components, subject to grade, heat-treatment, and machining review. |
| Aleaciones de cobre | Drawing-specified bronze grades | Selected bushings, bearings, and interfaces where wear behavior and mating conditions suit the alloy. |
| Material | Grade Examples | Selection and Use |
|---|---|---|
| Polímeros de ingeniería | PEEK, PTFE, PA | Insulators, seals, bushings, and lightweight interfaces; verify temperature, load, fluids, and documentation. |
| Insulating Laminates | Drawing-specified glass-epoxy grades | Electrical spacers, supports, and fixtures; review laminate direction, edge condition, and required ratings. |
Machined Aluminum

Machined Bronze
Machined PEEK
Grade examples are starting points, not substitutions for the drawing. Confirm material specification, temper or heat treatment, traceability, certificates, and substitution rules before production.
Acabados para piezas aeroespaciales
Define substrate compatibility, coating buildup, corrosion and wear duty, electrical contact areas, masking, and the required process specification.
Acabado mecanizado
Drawing-defined texture and edge condition, with controlled machining marks where permitted.
Anodizado
For suitable aluminum alloys. Specify coating type, thickness, masking, and dimensional allowance.
Granallado
A controlled matte texture where specified. Review media, cleanliness, and fatigue-sensitive surfaces.
Recubrimiento en polvo
For compatible applications and approved surfaces. Review cure temperature, film buildup, masking, and grounding.
Quality Controls from Review to Release
Controlled drawings, production planning, and documented inspection support consistent sourcing from the first part to repeat orders.
Weldo’s ISO 9001:2015 quality system supports drawing and revision control, calibration, inspection, and production records.
Drawing and Material Control
Confirm revision, material grade and condition, certificates when specified, and any restrictions on substitution.
Inspección dimensional
Plan CMM and other suitable measurement methods around critical datums, tolerances, access, and the inspection environment.
Project Records and Release
Agree dimensional, first-article, material, and finish records, then complete final review, protection, and packing.
State required AS9100 certification, Nadcap approvals, AS9102 first-article scope, approved-source restrictions, and document formats on the RFQ for written confirmation. Aerospace-specific approvals are not implied by ISO 9001 certification.
Aerospace Machining Questions
Plan the drawing, process, documentation, and repeat-order requirements before quotation.
¿Qué archivos se necesitan para solicitar un presupuesto de mecanizado aeroespacial?
Send the 3D model and controlled 2D drawing, with revision, material condition, datums, tolerances, finish, quantity, and inspection requirements. Include approved-source or certification requirements in the enquiry.
How are aerospace machining tolerances determined?
The drawing and its stated standards control acceptance. General tolerances, fits, and geometric controls must be explicitly defined. Selected features may be reviewed to ±0.005 mm under suitable manufacturing and measurement conditions; this is not a general tolerance for the whole part.
Can titanium and nickel-alloy components be machined?
The exact grade, condition, stock form, geometry, tooling, heat management, and inspection route are reviewed before confirming a production plan. Include any required material specification and heat-treatment records.
¿Se pueden facilitar los registros del primer artículo y de inspección?
Customer-defined first-article, dimensional, material, and finish records can be planned before quotation. If AS9102 is required, state the applicable revision and deliverables for written confirmation of the scope.
How are repeat orders controlled?
Current drawings and purchase requirements are checked against the approved programs, fixtures, inspection points, material requirements, and production records before the repeat order proceeds.
Which quality approvals should I state in the RFQ?
List required quality-system certifications, special-process approvals, approved-source restrictions, and document formats. The page’s ISO 9001 quality-system information does not establish AS9100 certification, Nadcap accreditation, or customer-specific approval.
