Capabilities
A practical starting point for drawing review
| Area | Available route | Planning note |
|---|---|---|
| Processes | 3-, 4- and 5-axis CNC; turning; turn-mill | Machine selection follows feature access and workholding review. |
| Materials | Aluminum, stainless steel, titanium, nickel alloys, engineering plastics | Grade and material records are confirmed from the drawing package. |
| Inspection | CMM, height measurement and optical inspection | Inspection method follows datum scheme and tolerance callouts. |
| Size envelope | Up to 2,000 mm length; turning diameter up to 600 mm | Conditional on machine, fixture, material and drawing review. |
| Fine tolerance | Claims as low as 3 μm | Conditional on geometry, material, process plan and verified inspection. |
Services
Machining and finishing for production-ready parts
CNC turning
Turning and turn-mill routes for shafts, housings and concentric features.
Joining and assembly
TIG, brazing and laser welding, with assembly defined from the drawing.
Surface finishing
Anodizing, passivation, plating, blasting, coating and polishing by specification.
Quality workflow
A reviewable path from drawing to release
Engineering review records the drawing revision, material, finish, inspection requirements and delivery assumptions before production planning.
Industries
Built around demanding engineering workflows
Aerospace
Traceable drawing review for flight hardware and ground-support components.
Medical
Controlled communication for device, instrument and automation components.
Optics
Fine features, surface requirements and inspection plans agreed before machining.
Automation
Low-volume parts for motion, robotics and laboratory equipment programs.
Materials
Material and finish choices stay tied to the drawing
Aluminum, stainless steel, titanium, nickel alloys and engineering plastics can be reviewed against the part specification.
Finishes under review
Anodizing, passivation, black oxide, electroless nickel, plating, blasting, painting and powder coating are available subject to supplier and specification review.
Control gates
Review, plan, machine, inspect and release
Review
Drawing revision, material, finish and inspection requirements are confirmed.
Plan
Process route, workholding and measurement points are agreed before machining.
Machine
Production follows the reviewed route and the approved drawing package.
Inspect/Release
Inspection evidence and packing requirements are reviewed before release.
Case studies available after evidence approval
Project details will be published after source evidence and publication authorization are reviewed.
Commercial assurances
Clear inputs for an international RFQ
Confirm the drawing revision, material, quantity, target delivery date, inspection documents, packing and any NDA requirements during review.
- MOQ: confirm per drawing
- Lead time: confirm after review
- Payment and transport: quote-specific
