What Is Micromachining?
Micromachining is an advanced, ultra-precision manufacturing process focused on creating extremely small parts, features, and structures with dimensions typically measured in microns (µm) — often ranging from 1 to 500 µm — and with tolerances in the sub-micron to single-digit micron range.
It is not simply "small-scale CNC," but a specialized discipline that pushes the limits of machine tools, cutting tools, and processes to achieve microscopic accuracy.
The Micromachining Characteristics
|
Scale |
Features often smaller than a human hair (~70-100 µm diameter). |
|---|---|
|
Tolerances |
± 1 µm or tighter is common. |
|
Tooling |
Uses micro-tools (end mills, drills) with diameters as small as 10-20 µm (thinner than paper). |
|
Machine Requirements |
Requires ultra-high-precision machines with nanometer-resolution feedback, extreme rigidity, and advanced vibration damping. |
|
Process Focus |
Achieves micro-scale geometry directly via material removal (subtractive), unlike semiconductor lithography (pattern-based). |
JADE-CNC’s Micro Manufacturing Capabilities
Micro Milling
Micro Milling uses physically scaled-down, rotating cutting tools (end mills and drills) to mechanically remove material and create extremely small, high-precision features.
JADE-CNC's micro-milling capabilities achieve tolerances as tight as 1 µm. Using cutting-edge equipment, we manufacture intricate micro components vital for high-precision applications. We specialize in producing parts where precision and size are critical, ensuring even the smallest details meet exceptional standards of accuracy and quality.
Key Features
Distinctions VS Conventional Milling
|
Aspect |
Conventional Milling |
Micro Milling |
|---|---|---|
|
Tool Diameter |
> 1 mm |
< 0.5 mm, down to hair-thin (10-20 µm) |
|
Tolerances |
± 0.01 mm (10 µm) or more |
± 0.001 mm (1 µm) o mejor |
|
Machine Rigidity & Spindle |
Standard rigidity, RPMs in the 1,000s |
Extreme rigidity, ultra-high-speed spindles (40,000 - 150,000+ RPM) |
|
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 (Electrical Discharge Machining) is a specialized, non-contact machining process that uses precisely controlled electrical sparks (discharges) to erode electrically conductive material at a microscopic scale. It can achieve sizes as small as 5µm and tolerances of up to 1µm.
Advantages in Micro EDM
- Hardness is irrelevant.
- No Mechanical Stress/Tool Deflection
- Extreme Aspect Ratios
- Tolerances within ± 1 µm
Main Types of Micro EDM
|
Type |
Process Description |
Primary Applications |
|---|---|---|
|
Micro Wire EDM |
Uses a thin, continuously fed brass or coated wire (as fine as Ф20 μm) as the electrode to cut intricate 2D profiles and shapes through a workpiece. |
Micro gears, micro-stents,intricate flat components, cutting extrusion dies. |
|
Micro Drilling EDM (or Hole Popping) |
Uses a thin, rotating or stationary tubular or solid electrode to "dril!" micro-holes. The most common type. |
Micro holes for fuel injectors, turbine blade cooling holes,spinnerets for fibers, starter holes for wire EDM. |
|
Micro Die-Sinking EDM |
Uses a pre-shaped, 3D micro-electrode to create a corresponding cavity or 3D shapein the workpiece. The electrode wears during the process. |
Complex micro-cavities in molds, micro-fluidic channels, textured surfaces. |
Most common Materials
Tungsten Carbide, Tool Steels, Inconel, Titanio, and specialized alloys.
Typical Applications
|
Medical |
Micro-holes for drug delivery devices, cutting edges for micro-surgical tools, components for minimally invasive devices. |
|---|---|
|
