Build-to-Print CNC Turning for Custom Components
FIWOK supports build-to-print CNC turning for custom shafts, pins, bushings, fittings, and other rotational components. Material, dimensions, threads, tolerances, finishing, documentation, and packing requirements can be reviewed according to the drawing, quantity, and confirmed project scope.
Typical CNC Turning Part Families
These examples show common rotational part families that may be suitable for CNC turning. Manufacturing requirements can be reviewed according to the drawing, material, part geometry, tolerance requirements, quantity, and confirmed project scope.
CNC turning can support individual prototype parts, small batches, and repeat-production requirements. The appropriate production route depends on part design, material, feature complexity, quantity, and secondary-operation needs.
Shafts and Axles
Rotational components with specified diameters, shoulders, grooves, threads, and related datum features.
Bushings, Sleeves, and Spacers
Parts defined by specified internal bores, outer diameters, lengths, and mating or assembly interfaces.
Pins and Small Turned Parts
Pins, dowels, and other small rotational parts with specified diameters, lengths, threads, grooves, or related features.
Turning Process Options for Different Part Requirements
CNC turning, Swiss turning, and automatic lathe turning can be considered according to part geometry, diameter, length, material, feature complexity, tolerance requirements, quantity, and confirmed project scope.
CNC Turning
Flexible Turning for Custom Parts
Suitable For: Custom rotational parts across prototype, batch, and repeat-production requirements, depending on geometry, material, features, and quantity.
Process Considerations: Turning features, threads, grooves, drilled or milled details, secondary operations, and finish requirements can be reviewed by project.
Swiss Turning
For Suitable Small-Diameter Parts
Suitable For: Small-diameter, longer-length, or feature-dense turned parts when geometry and quantity are suitable for Swiss turning.
Process Considerations: Part diameter, length-to-diameter relationship, material, tolerances, feature complexity, and expected quantity should be reviewed together.
Automatic Lathe Turning
For Suitable Repeat-Production Parts
Suitable For: Repeat-production parts with suitable geometry, stable specifications, and confirmed volume requirements.
Process Considerations: Part design, material, feature complexity, tooling needs, required quantity, and future demand should be evaluated before process selection.
CNC Turning Planning for Custom Part Requirements
CNC turning requirements can be reviewed according to part geometry, material, specified dimensions, threads, tolerances, quantity, secondary operations, finishing, and documentation needs. The appropriate production approach depends on the confirmed project scope.
Prototype and Production Requirements
Prototype quantities, repeat-production needs, material requirements, and expected volume can be reviewed to help determine an appropriate CNC turning approach.
Fit-Critical Features and Tolerances
Identify dimensions, threads, bores, diameters, mating surfaces, and other features that control fit, function, or assembly requirements.
Drawing and Manufacturing Review
Drawing information, material, turning features, secondary operations, finish requirements, and documentation needs can be reviewed as part of quotation planning.
Material and Finishing Options for CNC Turned Parts
Material and surface finishing options can be reviewed according to part geometry, specified material grade, functional requirements, appearance requirements, quantity, and confirmed project scope. Surface finishing is available as part of FIWOK-manufactured CNC turning projects.
Common Material Groups
- Aluminum: Common grades and tempers can be reviewed according to weight, strength, machining, and finish requirements.
- Stainless Steel: Material grade, part function, finish, and environmental requirements should be specified.
- Carbon and Alloy Steel: Options can be considered based on strength, machinability, heat treatment, and finish requirements.
- Brass and Copper: Suitable options may be reviewed for conductive, mechanical, or appearance-related part requirements.
- Engineering Plastics: Select materials may be evaluated according to geometry, application, temperature, and functional needs.
Finishing and Related Operations
- Anodizing: Available for compatible aluminum parts when specified by finish type, color, visible surfaces, and applicable requirements.
- Passivation: May be considered for suitable stainless-steel parts when specified in the project requirements.
- Conversion Coating: Can be reviewed according to material, finish standard, masking areas, and functional requirements.
- Plating and Black Oxide: Specified options may be reviewed based on material, surface requirements, and designated features.
- Mechanical Preparation: Deburring, blasting, brushing, or tumbling may be included based on part and finish requirements.
Laser marking, heat treatment, hardware installation, light assembly, documentation, and packing requirements can also be reviewed when specified in the RFQ and confirmed project scope.
