The pinnacle of precision manufacturing: CNC high-precision and low-reflectivity surface treatment technology  In the modern precision manufacturing field, the two core indicators of parts - dimensional accuracy and surface performance - often directly determine the quality and reliability of the final product. CNC (Computer Numerical Control) processing technology has long been the cornerstone for achieving micron-level or even nanometer-level dimensional accuracy. However, when the application scope expands to high-precision fields such as optics, aerospace, and semiconductors, another key indicator emerges: low reflectivity of the surface.  Combining high-precision machining with low-reflectivity surface treatment represents one of the highest levels of CNC manufacturing technology today. This is not only a test of the performance of the machine tools, but also a comprehensive challenge to materials science, tool path planning, and post-processing techniques.   I. Why is low reflectivity necessary? Beyond the "aesthetic" functional requirements  Low-reflectivity surfaces are far more than just for eliminating unnecessary reflections (or "anti-glare") to achieve aesthetic effects; behind this lies a profound functional need:  Optical system performance: In optical devices such as cameras, telescopes, microscopes, and laser radars, the reflected light from internal components (such as barrels, supports, and aperture blades) can form stray light, significantly reducing image contrast, causing ghost images, and even increasing signal noise. Low reflectivity surfaces can effectively absorb stray light, improving imaging quality and system signal-to-noise ratio. 2. Military and aerospace stealth: The high reflectivity of equipment surfaces is a significant characteristic of radar waves and infrared detection. Through low reflectivity treatment, it can significantly reduce its radar cross-section (RCS) and infrared characteristics, enhancing stealth performance and survivability.   3. Semiconductor and sensing technology: In the interiors of lithography machines and wafer processing equipment, any unnecessary reflection may interfere with extremely precise optical paths or sensor readings, leading to manufacturing defects. The shells of sensors themselves also require low reflectivity to ensure measurement accuracy.   4. Medical and research equipment: Such as endoscopes, high-precision experimental instruments, etc., they all need to minimize internal light interference to ensure the purity of observation and data.   II. How to Achieve It? The Integration of High-Precision CNC and Low Reflectivity Technology  To achieve a part with both high precision dimensions and low reflectivity is a multi-stage systematic project:  High-precision CNC processing: Foundation  · Ultra-high precision machine: Utilizing linear grating rulers with nanometer-level resolution, thermal compensation systems, highly rigid bed and spindle, and high-end five-axis CNC machines, this ensures the utmost precision in geometric shape and dimensions. · Precise cutting tools and strategies: Employing diamond tools or ultra-fine particle carbide tools, combined with optimized cutting parameters (rotation speed, feed rate, depth of cut) and tool paths (such as slow-tool servo turning), excellent surface quality (low roughness) is achieved at the initial stage of processing, laying a perfect foundation for subsequent low-reflection treatment.  2. Achieving low reflectivity surface treatment technology: The core of low reflectivity essentially involves altering the microscopic structure or chemical composition of the surface to enhance light absorption and reduce specular reflection. The main technical approaches include:  · Surface microstructure processing (texturing): · Technical principle: Utilizing the extremely high positioning accuracy of CNC machines, dense micrometer or nanometer-sized grooves, depressions, or complex three-dimensional structures can be machined on the surface of the parts. These structures can be regarded as "light traps", as light entering them undergoes multiple reflections and absorptions, making it difficult to escape again, thereby achieving the "blackening" effect. · Implementation method: The surface microstructure can be directly shaped through five-axis milling， femtosecond laser ablation， chemical etching， etc. · Special coatings/adsorptions： · Technical principle： On the machined base material， a layer of material with high light absorption properties， such as black chromium， black nickel， carbon nanotube (CNT) coating， or specific ceramic coating， can be covered through physical vapor deposition (PVD)， chemical vapor deposition (CVD)， or spraying processes. · Advantages： Strong selectivity， capable of designing coatings for different wavelengths (such as visible light， infrared， radar waves)， with extremely high absorption efficiency. However， the coating thickness must be strictly controlled to avoid affecting the high precision dimensions of the parts. · Chemical conversion treatment： · Technical principle： Through chemical methods (such as anodic oxidation， black oxidation)， a porous and rough chemical conversion film can be generated on the metal surface (especially aluminum， steel). This film itself has light absorption properties. Common examples include black anodic oxidation of aluminum alloys.  · Note： The treatment process needs to be precisely controlled to avoid affecting the precise dimensions.  3. Collaboration and Challenges: The greatest challenge lies in the fact that subsequent low-reflection treatments (such as coating, oxidation) will introduce extremely thin additional layers, which may alter the final size of the part. Therefore, "compensatory design" must be carried out at the initial high-precision CNC processing stage, taking into account factors such as coating thickness in advance, and conducting "negative allowance" processing to ensure that the final size of the processed part still perfectly meets the design requirements.    

In the world of manufacturing, "Bigger is better" is not the only truth. From medical implants and microelectronic components to precision gears and optical equipment in the aerospace field, the demand for tiny and highly complex parts is growing explosively. The core technology that meets this demand is Micro CNC Machining. This is a precision manufacturing art that reduces the power of traditional CNC (Computer Numerical Control) machining to an incredible extent.   This article will take you on a deep dive into the world of micro-CNC machining, exploring its unique craftsmanship, astonishing precision levels, and just how small parts it can produce.   What is micro CNC machining? Micro-cnc machining is essentially subtractive manufacturing. It gradually removes material from a solid material (referred to as a "blank") through computer-controlled precision machine tools, ultimately forming a designed geometric shape. The key difference between it and traditional CNC machining lies in the size, precision and level of detail.   Generally, when the feature dimensions of a part are less than 100 micrometers (0.1 millimeters), or the tolerance requirement reaches the ± several micrometer level, it is classified as micro-machining. This not only requires ultra-precise machine tools, but also places extreme demands on cutting tools, the environment and process control.   The process and key technologies of micro CNC machining   The core process of micro-machining is similar to that of traditional CNC: CAD design → CAM programming → machine tool setting → processing → inspection. But every step of it is full of unique challenges.   Ultra-precision machine tools: Micro CNC machine tools are wonders of engineering. They usually have: Extremely high spindle speed: The spindle speed can reach 30,000 to 160,000 RPM or even higher. High-speed rotation enables the use of extremely small cutting tools (with diameters possibly thinner than a human hair) while maintaining sufficient cutting speed to ensure minimal cutting force and perfect surface finish. · Ultra-precise motion platform: Utilizing linear motors and high-resolution grating rulers, it can achieve sub-micron level (less than 1µm) movement and positioning accuracy. Every tiny movement of the machine tool must be precise and error-free. · Outstanding rigidity and stability: Despite the small size of the parts, the machine tool itself must be extremely sturdy and vibration-resistant. Any slight thermal fluctuation or vibration will directly destroy the parts. Therefore, machine tools are usually installed on anti-vibration platforms and are in an environment with strict temperature and humidity control.   2. Micro-cutting tools: This is the soul of micro-machining. The diameters of these cutting tools (mainly end mills) can be as small as 0.1 millimeters (100 micrometers) or even smaller. For intuitive understanding, the average diameter of a human hair is approximately 75 micrometers. These cutting tools are not only extremely difficult to manufacture, but also extremely fragile, posing strict requirements for clamping, tool setting and cutting parameters.   3. Advanced software and control: CAM software must be capable of generating tool paths for processing micron-level features. When programming, special consideration should be given to the fragility of the cutting tool. More intelligent cutting strategies, such as fine-tuning cutting (Peck Milling) and more optimized feed rates, should be adopted to prevent tool breakage and ensure accuracy.   4. Professional Materials: Micro CNC can process various materials, including:   · Metals: aluminum, stainless steel, titanium alloy (commonly used in medical implants), brass, nickel alloy. · Plastics: PEEK, ABS, polycarbonate, ULTEM. · Others: Ceramics, composite materials. The material must have a uniform microstructure. Any impurities may cause chipping of micro-cutting tools or defects in parts.   An astonishing level of precision   The precision of micro-CNC machining is the foundation of its existence. Its capabilities are usually measured by the following indicators: · Tolerance: The conventional tolerance can reach ±5 microns (±0.005 millimeters), and on high-precision machine tools, it can even achieve a tolerance of ±1 micron. · Surface Finish: It can achieve a mirror-like finish of Ra < 0.1 microns, and almost no secondary polishing is required. · Feature Size: It can stably produce features with a width and pore size as small as 25-50 microns.   How small can it be? Explore the limits of size   So, where exactly is the limit of micro-CNC machining? The following are some real-world examples that demonstrate its almost magical abilities:   · Finer than human hair: It can mill grooves and smaller shafts that are narrower than the diameter of a human hair (~75µm). · Micro-gears: All-metal gears can be manufactured for micro-robots or precision instruments, with perfect tooth profiles and extremely small tooth clearings. The entire gear may only be the size of a needle tip. Medical stents: Medical devices such as vascular stents are typically made from laser-cut tubes, but micro-CNC can be used to process their complex connectors or manufacture prototypes. · Microfluidic chip: A complex channel network thinner than a human hair is fabricated on a plastic or metal block for biochemical analysis. · Optical components: Manufacturing tiny lens arrays, fiber optic connectors, and other precision optical parts that require nanometer-level surface accuracy. · Watch parts: Many tiny gears, escapement forks and Bridges in high-end mechanical watches rely on micro-machining technology.   Although some technologies (such as photolithography) can produce smaller nanoscale structures, the unique advantage of micro-CNC lies in its ability to directly manufacture truly three-dimensional, functional metal and plastic parts with engineering materials, and it has excellent mechanical properties and complex geometries.   Application field   Micro CNC machining is an indispensable part of many high-tech industries:   · Medical and Life Sciences: Surgical tools, implants, endoscopic parts, microfluidic devices. · Aerospace and Defense: Micro-sensors, gyroscopes, lightweight components, unmanned aerial vehicle parts. · Electronics and Semiconductors: Connectors, heat sinks, test fixtures, chip packaging molds. · Optics and Photonics: Lens mounts, infrared tubes, laser components. · Automotive industry: Micro-sensors, fuel injection system parts.   Conclusion   Micro-cnc machining represents the pinnacle of subtractive manufacturing technology. It combines the precision of computer control with the ultimate craftsmanship of mechanical engineering, creating miracles at scales that are hard for our naked eyes to see clearly. It is not merely about making things smaller, but rather about realizing grand engineering dreams in a reliable and repeatable way in the microscopic world, driving the boundaries of innovation in various fields from healthcare to consumer electronics. With the continuous advancement of technology and materials, we are bound to witness the creation of smaller, more complex and smarter micro-components in the future.
