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.
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.
