Custom CNC ManufacturingCNC Machining ServicesTurn your drawing into a CNC machining plan built around the actual part requirements. We support metal and plastic components from rapid prototypes and one-piece orders to low- and medium-volume production, using CNC milling, turning, 5-axis machining, and Swiss turning where each process fits the geometry.Send us your drawing or 3D model together with the material, critical tolerances, finish, inspection criteria, quantity, and target schedule. We will review the complete requirement and prepare a project-specific quotation with a realistic process and delivery assessment.Request a CNC Quote→Explore CNC Capabilities ↓Image placeholderCNC machining / finished partsRecommended ratio 3:2DrawingProcess routeAcceptanceProcess OptionsMilling, turning and specialist routes→Materials & FinishesPlan the complete requirement→Critical FeaturesDatums, setups and tolerances→Project StageOne piece through repeat quantities→Process SelectionCNC Machining Options for Different Part RequirementsCNC process selection starts with the part. Features, part shape, material, critical dimensions, surface requirements, quantity, and inspection criteria all affect the recommended approach.CNC MillingCNC milling is commonly considered for prismatic parts and components with machined faces, pockets, slots, holes, profiles, and features at different orientations.Identify critical datums and mating surfaces.Show thread, tool-access and edge requirements.Flag features across several faces for 5-axis review.CNC milling imageCNC TurningCNC turning is commonly considered for round or rotational parts such as shafts, pins, bushings, sleeves, and components with concentric diameters.Define diameter, bore and shoulder relationships.Include grooves, threads and runout requirements.Flag secondary milled features in the drawing.CNC turning imageMilling route5-Axis CNC MachiningWe provide 5-axis CNC machining for projects that require evaluation of complex geometry or features across multiple faces. Tool access, workholding, datum strategy, tolerance relationships, and inspection needs determine the route.Turning routeSwiss TurningWe provide Swiss turning services for suitable turned-part requirements. Share the material, part length and diameters, critical features, quantity, tolerance, and acceptance criteria for a complete review.Complete SpecificationMatch Material and Finish to the Machining PlanMaterial condition and finishing requirements can change cutting strategy, stability, dimensional allowance, protected areas, and the point at which a feature is accepted.MaterialMachiningFinishMaterial inputMetals and Engineering PlasticsMetals: aluminum, stainless steel, carbon steel, brass, copper, bronze, and titanium.Engineering plastics: POM / acetal, nylon, polycarbonate, ABS, PTFE, and PMMA / acrylic.Define the grade, temper or condition, certification requirements, and substitution restrictions. Specific grades and suitability are reviewed for each project.Finish inputSecondary Process RequirementsOptions can include anodizing, hard anodizing, chemical conversion coating, blasting, polishing, brushing, passivation, plating, powder coating, painting, and heat treatment.Specify color, texture, coating standard, masking areas, appearance criteria, and any threads, fits, contact areas, sealing surfaces, or cosmetic faces that need protection.Machining LogicPlan the Features That Drive the CNC RouteThe most important machining questions often sit between dimensions. Clear functional relationships help the machining and inspection plans work from the same requirement.Datum ACritical boreMating faceFeature relationshipsPlan access, stability and verification together.Datums, Setups, and Feature RelationshipsIdentify functional datums and features that must be controlled in the same setup. Flag thin walls, deep pockets, long overhangs, interrupted cuts, small internal radii, and surfaces that require protection.Tolerances Where Function MattersGeneral CNC machining tolerance is ±0.01 mm. Actual achievable tolerances depend on geometry, material, process, feature relationships, and inspection method. Final requirements are confirmed against the drawing and order.Function Before Blanket PrecisionApply tighter controls where fit, motion, sealing, alignment, or assembly requires them. Show shared datums and cross-setup relationships clearly so they can be reviewed together.Acceptance PlanningConnect CNC Features to Acceptance RequirementsInspection planning should follow the features that drive machining decisions. Positional relationships, concentric diameters, mating faces, threads, and finished interfaces may each require a different verification approach.If anodizing, plating, heat treatment, or another secondary process changes a feature, define whether acceptance applies before or after finishing.ISO 9001:2015 certifiedQuality requirements are reviewed against the project.Review Quality Requirements→Image placeholderCNC part inspectionRecommended ratio 4:3Quantity & PlanningMatch the CNC Route to Your Project StageThe same geometry can call for different planning priorities as a project moves from a first component to repeat quantities.Prototype / one pieceProve the Required PartOrders can start from one piece. The review concentrates on geometry, material, fit, and functional features. State at the beginning if the prototype must represent production material or finishing.Prototype quotation targetWe aim to provide quotations for all prototype projects within 24 hours. The actual quotation timeline will be determined after reviewing factors such as part complexity, quantity, and processing requirements, and we will let you know the expected timing in advance.Low / medium volumePlan for Repeat RequirementsFor repeat quantities, process planning also considers setup consistency, inspection frequency, finishing flow, and features that affect repeatability.Capacity and schedule are evaluated for the specific part, process, and quantity.Production lead time is confirmed during quotation or order review.We generally quote FOB Shenzhen.CNC Decision SupportCNC Process Selection QuestionsUse these questions to prepare a clearer drawing package and choose the right process review.MillingTurning5-AxisSwissHow do I decide between CNC milling and CNC turning?Start with the dominant geometry. Parts defined mainly by faces, pockets, slots, holes, and profiles are commonly evaluated for milling. Parts defined mainly by concentric diameters, bores, shoulders, grooves, and threads are commonly evaluated for turning. Mixed geometry may call for secondary operations or a combined route.When should 5-axis CNC machining be evaluated?Consider a 5-axis review when important features sit across multiple faces, tool access is restricted, or datum relationships become difficult to maintain through repeated repositioning. The route is selected only when it supports the geometry, workholding, tolerance relationships, and inspection plan.Which parts are candidates for Swiss turning?Swiss turning can suit small or slender rotational parts whose length-to-diameter relationship, feature layout, quantity, and tolerance requirements support that process. Secondary features, material behavior, and inspection access can change the preferred route.Why do datum relationships matter to CNC planning?Datums define how critical features relate to one another. When related features are split across setups, the machining and inspection plan must account for how those relationships will be maintained and verified.Should finishing requirements be included before quotation?Yes. Finishing can affect masking, edge condition, dimensional allowance, surface appearance, and the stage at which a feature is accepted. Specify the finish, controlled surfaces, cosmetic criteria, and whether dimensions apply before or after finishing.Start with the complete requirementRequest a CNC Machining QuoteSend your drawing, model, material specification, quantity, critical requirements, finish, and inspection criteria.
