Prototype SupportOne-off and low-volume parts can be reviewed without a strict CNC minimum order quantity.

Repeat ProductionApproved programs, fixtures and inspection requirements support consistent reorders.

Secondary OperationsDeburring, threading, inserts, finishing, marking and assembly can be coordinated.

Confidential ProjectsCustomer files are handled confidentially, with NDA support available.

Selecting the Machining Route

CNC MILLING

Prismatic Components

Housings, plates, brackets, fixtures, pockets and features located on several faces.

CNC TURNING

Rotational Components

Shafts, bushings, sleeves, collars, threaded connectors and concentric features.

MILL-TURN

Combined Geometry

Round parts that also require flats, slots, cross holes or off-axis mounting features.

4-AXIS

Multi-Side Access

Rotary positioning can reduce handling for features distributed around the component.

5-AXIS

Angled & Complex Features

Useful where tool access, compound angles or fewer setups influence the process route.

SECONDARY

Finished-Part Coordination

Machining can be combined with surface treatment, marking, hardware and assembly needs.

Process Comparison for Project Planning

Route	Typical Geometry	Features to Review	Example Components
CNC Milling	Prismatic, flat or multi-face	Deep pockets, thin walls, internal radii and clamping access	Housings, brackets, mounting plates and fixtures
CNC Turning	Round or rotational	Concentricity, bore-to-shaft fits, shoulders and long slender sections	Shafts, spacers, sleeves, collars and connectors
Mill-Turn	Rotational plus prismatic	Datum transfer, cross features, angular position and setup sequence	Valve bodies, custom connectors and complex shafts
Multi-Axis	Angled or complex surfaces	Tool reach, collision clearance, workholding and inspection access	Complex housings, automation parts and precision structures

Materials and Finishing Options

Commonly Reviewed Materials

Aluminum: 6061, 6063, 7075 and drawing-specified alloys
Stainless steel: selected grades according to corrosion and strength needs
Steel: carbon, alloy and tool steels as required
Other materials: brass, copper, titanium and selected engineering plastics

Secondary Operations

Anodizing, plating, passivation and specified coatings
Brushing, polishing, sandblasting and cosmetic finishing
Threading, tapping, inserts and hardware installation
Laser marking, part identification and controlled packaging
Assembly coordination where multiple parts or processes are involved

Manufacturing Risks Reviewed Before Release

Thin WallsMaterial removal and clamping can influence rigidity and released dimensions.

Deep CavitiesTool reach, chip evacuation and cutting stability may affect the machining plan.

Small Internal RadiiSmall tools can increase machining time and may limit practical depth.

Related FeaturesBore-to-bore, hole-to-datum and face-to-face relationships may require focused control.

Limited WorkholdingParts with few clamping surfaces may require dedicated fixture planning.

Post-Machining FinishAnodizing, plating or heat treatment may affect final interfaces and inspection timing.

From Quotation to Repeat Production

File Review

Confirm drawing revision, material, quantity, tolerances and finish.

DFM & Route

Review tool access, workholding, setups and secondary operations.

Programming

Prepare toolpaths, fixtures and machining parameters for the approved route.

Production

Machine samples or batches with selected in-process checks.

Final Review

Verify agreed dimensions, finish, documentation and packaging.

Quality Control for Critical Features

Datum Control

Checks follow defined references and feature relationships shown on the drawing.

Fit & Assembly

Bores, shafts, holes, threads and mating faces receive appropriate attention.

Surface Condition

Edges, visible areas and finishing results are reviewed to agreed criteria.

Project Records

Required inspection or material records should be identified before quotation.

Tolerance note: Requirements such as ±0.01 mm may be achievable for suitable features. Final capability depends on geometry, material, part size, process route, quantity, surface treatment and measurement method.

Scaling from Prototype to Repeat Orders

Prototype machining validates geometry, assembly and finishing before repeat production. When a project moves forward, approved files, programs, fixture information and inspection requirements can support future batches.
