Micro Machining for Fine Features and Small Parts
Micromachining is used for small CNC parts, miniature components, fine holes, thin walls, slots, small pockets, detailed profiles, and features that require careful tool access and burr control.
Before quotation, JADE-CNC reviews the drawing, material, feature size, depth, wall thickness, surface finish, and inspection method so the machining route matches the actual part requirement.
The Micromachining Characteristics
|
Scale |
Fine features, small holes, thin walls, and compact parts where tool access and inspection method must be planned carefully. |
|---|---|
|
Tolerances |
Confirmed by drawing, material, feature geometry, fixture strategy, and inspection method. |
|
Tooling |
Uses small-diameter tools and EDM-related methods when the geometry, material, and feature access require them. |
|
Machine Requirements |
Requires stable fixturing, controlled tool runout, suitable cutting strategy, and inspection planning for miniature features. |
|
Process Focus |
Achieves micro-scale geometry directly via material removal (subtractive), unlike semiconductor lithography (pattern-based). |
What JADE-CNC Reviews Before Micro Machining
Feature Size
Small holes, slots, grooves, thin walls, and fine profiles are reviewed against tool access, depth, and inspection feasibility.
Material Behavior
Aluminum, stainless steel, copper, brass, titanium, and engineering plastics are reviewed based on burr risk, deformation, and finish needs.
Tool Access
Small tools, deep features, corner radii, and reach limitations are checked before confirming the machining method.
Burr and Edge Control
Edges, holes, threads, slots, and cosmetic faces are reviewed for deburring, cleaning, and surface finish requirements.
Inspection Method
Critical dimensions may require microscope review, gauges, CMM checks, visual inspection, or customer-specified measurement records.
Micro Milling
Micro milling uses small rotating cutting tools to machine fine features, small pockets, slots, holes, and detailed surfaces in miniature components.
JADE-CNC reviews micro-milled parts by material, feature depth, wall thickness, tool access, burr-control requirements, surface finish, and inspection method before confirming the machining route and tolerances.
Key Features
Micro Milling vs. Conventional Milling
|
Aspect |
Conventional Milling |
Micro Milling |
|---|---|---|
|
Tool Diameter |
> 1 mm |
Small-diameter tools selected by feature size, material, depth, and access. |
|
Tolerances |
± 0.01 mm (10 µm) or more |
Project-specific tolerance review based on the drawing and inspection method. |
|
Machine Rigidity & Spindle |
Standard rigidity, RPMs in the 1,000s |
Stable spindle, fixture, tool runout, and cutting strategy are important for fine features. |
|
Chip Formation |
Continuous or segmented chips |
Dust-like, fragmented chips; chip evacuation is a major challenge |
|
Dominant Force |
Cutting force |
Tool deflection, runout, and vibration become primary limiting factors |
Micro EDM
Micro EDM is used when conductive materials require fine slots, small holes, thin profiles, or detailed features that are difficult to machine with cutting tools. The final feasibility depends on material conductivity, feature size, depth, tolerance requirement, surface condition, and inspection method.
JADE-CNC reviews Micro EDM requirements by drawing before confirming whether EDM, micro milling, drilling, or another machining route is more suitable.
Advantages in Micro EDM
- Hardness is irrelevant.
- No Mechanical Stress/Tool Deflection
- Extreme Aspect Ratios
- Tolerances within ± 1 µm

FAQ
Micro machining is used for small parts, fine holes, thin walls, slots, miniature components, and detailed features that require careful process review.
A 3D CAD file and 2D drawing are recommended, especially when small features, tight tolerances, burr control, or inspection requirements are important.
Small holes can be reviewed by diameter, depth, material, tolerance, burr risk, and inspection method before confirming feasibility.
Common materials include aluminum, stainless steel, brass, copper, titanium, steel, PEEK, and other engineering plastics.
Burr risk is reviewed based on material, edge condition, feature size, machining method, deburring access, and functional surfaces.
Yes. It can support prototypes, functional samples, and low-volume small parts when the drawing and inspection requirements are clear.
Micro EDM may be useful for conductive materials with small holes, fine profiles, or difficult-access features that are not ideal for cutting tools.
Inspection may include microscope review, visual checks, gauges, CMM checks, dimensional reports, or customer-specified inspection records.
No. Marking only critical features helps improve manufacturability, inspection clarity, and quotation accuracy.
Provide material grade, feature size, critical dimensions, surface finish, burr requirements, inspection needs, and expected quantity.
