Overview
Micro Machining for Small and Delicate Custom Parts
Micro machining is used for small custom parts or components with miniature features that require more careful control than standard machining. As part size becomes smaller, burr condition, edge quality, feature definition, and handling consistency become more important throughout production.
For many small precision parts, the challenge is not only achieving the required dimensions, but also maintaining part integrity, clean edges, stable repeatability, and suitable packaging after machining.
Small-Part Manufacturing Review
Why Small Precision Parts Need a Different Manufacturing Review
Small precision parts are not only difficult because of tight dimensions. The real risks often come from burrs, scratches, deformation, part mixing, unstable clamping, and inspection limitations. A small burr or handling mark can affect assembly much more seriously than on larger machined parts.
That is why OUJI reviews each micro machining project from the drawing, material, feature size, burr direction, handling method, inspection points, and packaging requirements before quotation.
Small burrs may affect assembly, contact surfaces, or functional movement.
Miniature parts are easier to scratch, deform, mix, or lose during production.
Fine grooves, shoulders, small bores, and tiny edges need clearer inspection planning.
Material, clamping, tooling, and feature ratio should be reviewed before quoting.
What We Make
Typical Micro Machined Parts We Support
OUJI supports small custom components for prototypes, pilot runs, low-volume production, and repeat custom orders where feature consistency and careful follow-up matter.
iniature Shafts & Stepped Pins
Small-diameter shafts, stepped pins, rollers, and compact turned parts with fine diameters, grooves, shoulders, chamfers, and functional surfaces.
Precision Pins, Inserts & Contact Parts
Custom pins, inserts, contact parts, and small cylindrical components for assemblies, fixtures, electronic devices, connector systems, and compact mechanisms.
Small Sleeves, Bushings & Spacers
Miniature sleeves, bushings, spacers, and short cylindrical components where ID, OD, concentricity, end-face quality, and surface condition affect assembly fit.
Connector and Functional Micro Components
Small custom components with grooves, slots, threads, shoulders, small bores, or stepped diameters for electronics, instruments, automation, and precision devices.
Micro Machining Capabilities
Small Features, Burr Control, and Handling Review
Micro machining capability depends on part size, material, feature depth, wall thickness, diameter ratio, tool access, burr condition, tolerance requirements, and post-machining handling needs.
Best-Fit Micro Machining Projects
| Project Type | Best Fit | Review Focus |
|---|---|---|
| Small turned parts | Miniature shafts, pins, sleeves, spacers, inserts, bushings, and compact round parts | Diameter stability, length ratio, concentricity, burr direction, and handling risk |
| Fine-feature components | Grooves, shoulders, threads, small bores, chamfers, steps, and contact features | Tool access, feature clarity, edge condition, inspection method, and repeatability |
| Burr-sensitive parts | Connector parts, contact pins, assembly-critical components, and functional micro parts | Material behavior, cutting direction, deburring method, surface protection, and packaging |
| Low-volume production | Prototype batches, pilot runs, small production lots, and repeat custom orders | Process stability, sorting, inspection records, part separation, and packaging consistency |
| Projects needing extra review | Thin-wall parts, very slender parts, deep small holes, fragile features, or cosmetic surfaces | Machining feasibility, deformation risk, inspection limits, finishing risk, and cost impact |
Final feasibility should be reviewed from the drawing. Small features, thin sections, slender geometry, strict cosmetic needs, and post-finishing requirements may affect process stability and cost.
Materials
Materials Better Suited for Small Precision Turned Parts
For micro machined and small precision turned parts, material selection is not only about strength or cost. Machinability, burr behavior, cutting stability, surface condition, small-feature rigidity, and inspection feasibility all affect whether the part can be produced reliably.
Preferred Materials
These materials are generally more suitable for small turned parts, miniature shafts, pins, sleeves, spacers, inserts, and connector-related components.
- Brass
- Copper alloy, project-based review
- Stainless steel, common grades by drawing
- Aluminum, suitable part geometry required
- Free-cutting steel, project-based review
Materials Requiring Extra Review
Some materials may be possible, but they should not be promised before reviewing diameter, feature size, tolerance level, burr sensitivity, and production quantity.
- Titanium
- Hardened steel
- High-strength alloy steel
- Engineering plastics with very small features
- Thin-wall or fragile material sections
What We Review Before Quoting
Instead of listing every possible material, OUJI reviews whether the material is practical for the actual drawing and production route.
- Burr behavior after turning
- Small diameter stability
- Groove, shoulder, and edge quality
- Deburring and cleaning method
- Surface treatment compatibility
- Inspection and handling risk
Process Control & Inspection
Inspection Support for Small Features, Burrs, and Critical Dimensions
For small precision parts, normal visual checking is often not enough. OUJI can support magnified visual inspection, selected dimensional checks, burr and edge review, and project-based inspection records according to drawing requirements.
Stable Small-Part Machining
Small turned parts, pins, sleeves, shafts, inserts, and compact components require stable machining conditions, suitable tooling, and careful control of fine features.
Magnified Visual Inspection
For small features, grooves, edges, fine diameters, and burr-sensitive areas, magnified inspection helps review part condition more clearly than normal visual checks.
Burr & Edge Review
Burr-sensitive areas can be reviewed based on feature size, cutting direction, material behavior, and drawing requirements.
Critical Dimension Checks
Key diameters, grooves, shoulders, bores, and functional features can be checked according to project requirements.
Handling Protection
Small parts are easier to scratch, mix, or deform, so handling and separation methods should be considered during production.
Drawing-Based Review
Critical features, tolerance notes, surface requirements, and inspection points should be confirmed before quotation and production.
Quality Standards
Quality Control Focus for Micro Machining Projects
Micro machining quality depends on more than machining accuracy. We review drawings, material, small feature risks, burr condition, inspection points, finishing needs, and packaging requirements before production.
Fine diameters, grooves, shoulders, threads, small bores, fragile areas, and critical functional features are reviewed before machining.
Material grade, machinability, burr behavior, tool access, deburring method, and finishing requirements are checked based on the drawing.
For critical small components, dimensional checks, selected inspection records, and project-based documentation can be arranged.
ISO 9001
