CNC Micro Milling
Complexity and Detail: Many contemporary applications, especially in fields such as electronics and medical devices, require components with intricate details. Due to limitations in tool sizes, these details are often unattainable through conventional milling.
- Product Introduction
With the development of industries, there has been a surge in demand for compact, efficient, and highly detailed components. This growing need has propelled micro milling to the forefront of precision manufacturing, and the reasons are as follows:
Complexity and Detail: Many contemporary applications, especially in fields such as electronics and medical devices, require components with intricate details. Due to limitations in tool sizes, these details are often unattainable through conventional milling.
Material Efficiency: Fundamentally, micro milling removes less material compared to standard milling. This translates to reduced waste and optimization of the use of typically expensive materials.
Wide Range of Material Applications: Micro milling can be applied to a variety of materials, ranging from metals to plastics and even ceramics. This versatility ensures its relevance across multiple industries.
Precision: As we delve into advanced technological realms, the margin of error continues to shrink. Micro milling provides the required precision, often down to the micron level.
Small-scale Production: Not all components have production quantities in the millions. The operation of certain specialized parts may be limited, and micro milling offers an effective solution for such scenarios.
The essence of the micro milling process lies in its tools. As the name suggests, these are miniature versions of conventional end mills, but with distinctive features:
Material: These tools are typically made from solid carbide to provide the necessary hardness and wear resistance. Coatings such as Titanium Nitride (TiN) or diamond may also be added to enhance performance.
Geometry: Due to their smaller size, micro end mills often have unique geometric shapes to prevent tool breakage and ensure precise cutting. For instance, chip evacuation groove designs are optimized for efficient chip removal.
Diameter: Typically, the diameter of these tools ranges from 0.1 millimeters to 1 millimeter, but even smaller tools may be available for specific applications.
Other Tools: In addition to end mills, micro drills, micro reamers, and various specialized tools are also coming into play, each designed for specific applications.
Micro Manufacturing Technologies: In addition to computer numerical control (CNC) micro machining, other micro manufacturing technologies such as micro injection molding, micro 3D printing, and micro electrical discharge machining (micro-EDM) can also be employed for the production of small-scale components.

FAQ
Q: What's the lowest thickness for the turning process I can use in my design to avoid warpage?
We recommend a minimum thickness of 0.8 millimeters for metal and 1.5 millimeters for plastic. However, this value is highly dependent on the size of the components to be manufactured. For instance, you may need to lower the minimum thickness limit for large parts and increase it for smaller parts to prevent warpage.
Q: What is the difference between traditional EDM and wire cut approach?
The primary distinction between wire EDM (Electrical Discharge Machining) and EDM (Electrical Discharge Machining) lies in the use of brass or copper wire as the electrode in wire EDM, while EDM does not involve the use of wire structures. In terms of functionality, wire EDM technology can generate smaller angles and more intricate patterns compared to EDM.
