CNC milling service

CNC milling service for custom machined parts

Request CNC milling quotes for aluminum, stainless steel, brass, copper, steel, and engineering plastic parts with drawing-based DFM review.

Service scope

What this CNC service covers

Prismatic parts

Plates, blocks, covers, housings, brackets, and fixture components.

Pockets and slots

Machined pockets, steps, slots, counterbores, tapped holes, and profile features.

Prototype milling

Engineering samples for assembly, fit, and function validation.

Low-volume milled parts

Short-run and bridge production when design requirements are stable.

DFM for milled geometry

Review deep pockets, internal radii, thin walls, tolerance callouts, and tool access.

Finish-ready machining

Prepare milled parts for specified surface finish where geometry allows.

Materials and RFQ inputs

CNC milling RFQs commonly include aluminum, stainless steel, carbon steel, brass, copper, POM, nylon, and other engineering plastics. Specify grade or equivalent standard when possible.

Files and quote details

Useful files include STEP, STP, IGS, IGES, X_T, SLDPRT, DXF, DWG, and PDF drawings.

Include quantity, material grade, surface finish, critical tolerances, thread requirements, target lead time, and destination country.

Quality and DFM review

Before production, quote-critical features can be reviewed for machinability, tolerance risk, material suitability, surface finish expectations, and inspection requirements.

Tolerance discussion

Clarify fit/function dimensions and avoid unnecessary tight tolerances on non-critical features.

Inspection before shipment

Request dimensional checks or documentation when your project needs verification.

Prototype to batch

Validate samples first, then quote low-volume or batch machining when design is stable.

CNC RFQ FAQ

What milled part files are useful?

STEP/STP files are preferred for 3D geometry, with PDF or DWG/DXF drawings for tolerances, threads, and finish notes.

Can tight pockets or thin walls be quoted?

They can be reviewed, but feasibility depends on tool access, material, wall thickness, depth, and tolerance requirements.

Can prototypes and small batches use the same supplier?

Yes. Prototype samples can be followed by low-volume or batch milling after design confirmation.
