Precision CNC Machining for Micro Parts | 40% Faster Production

CNC machining for micro parts focuses on the production of extremely small components with dimensions ranging from a few millimeters down to micrometers, requiring specialized equipment and techniques to achieve sub-micron precision. Micro machining involves using miniature cutting tools and high-precision CNC machines with fine resolution (often down to 1μm or better) to create intricate features on small parts. Materials commonly used in micro machining include stainless steel, titanium, aluminum, and engineering plastics, which are machined into components for medical devices, electronics, and optical instruments. For example, CNC-machined micro gears for miniature motors or tiny surgical instruments for minimally invasive procedures require precise geometries and smooth surfaces. The challenges in micro machining include tool wear, heat dissipation, and maintaining stability at such small scales, which are addressed through high-speed spindles, minimal cutting forces, and advanced cooling systems. Surface finish is critical for micro parts, as even minor imperfections can affect functionality, with processes like micro polishing or electropolishing used to refine surfaces. CNC machining for micro parts also requires specialized inspection techniques, such as optical microscopy and scanning electron microscopy (SEM), to verify dimensions and surface quality, ensuring that these tiny components meet the strict requirements of their applications.
