Shengqi reviews engineering drawings and CAD data for custom precision parts, then coordinates machining, inspection, surface finishing, and delivery according to the project requirements.
Parts are reviewed against the supplied 3D model, dimensioned drawing, material, finish, and critical interface requirements.
Dimensional checks are planned around the features that affect fit, function, assembly, and repeat production.
Suitable for prototypes, engineering samples, small production runs, and repeat orders that require consistent part definition.
The figures below are published equipment specifications, not a blanket tolerance promise for every part. Final achievable tolerance depends on geometry, material, size, datum structure, workholding, and surface treatment, and is confirmed during drawing review.
| Equipment or Method | Published Reference | Project Use |
|---|---|---|
| DMG MORI DMU50 machining center | Listed machining accuracy: 0.002 mm | Reference capability for precision milled components |
| FANUC CNC machining center | Listed machining accuracy: 0.01 mm | Machining of custom housings, plates, brackets, and components |
| Automatic coordinate measuring machine | Dimensional verification | Inspection of critical dimensions and part features |
| Height gauge and image measuring instrument | Feature and height measurement | Process and final checks for selected part requirements |
Useful when an engineering team needs to verify fit, assembly, appearance, or function before a larger release.
Suitable for trial production and orders in the dozens or hundreds, depending on part complexity, material, and finishing.
Released drawings, approved materials, inspection requirements, and revision control help support later orders.
Send STEP or STP files for 3D geometry when possible, together with a dimensioned PDF drawing. DWG, DXF, IGES, IGS, and Parasolid files can also be reviewed when available.
Include material or acceptable alternatives, quantity, critical tolerances, surface finish, heat treatment, cosmetic requirements, packaging, and target delivery date.
We review the files and requirements, confirm questions and production scope, then provide pricing and lead-time information for the approved specification.
There is no single lead time for every precision part. Prototype and production timing depends on part geometry, material availability, quantity, inspection requirements, and any anodizing, etching, laser engraving, painting, dyeing, or assembly work. The confirmed lead time is included in the quotation after drawing review. If you have a required delivery date, include it with the RFQ so the schedule can be evaluated at the start.
