What are High Precision Machined Parts?

‌High precision machined parts refer to parts with machining tolerances in the single-digit micron range, usually involving submicron or even nanometer-level precision machining technology. ‌ This machining method can ensure that the dimensional accuracy and surface roughness of the parts meet very high standards, and is suitable for the production of parts that require extremely high precision and complex shapes. ‌

The characteristics of high precision machined parts include: ‌

High dimensional accuracy‌: The dimensional accuracy of high precision machined parts is usually in the single-digit micron or even submicron range. For example, the dimensional accuracy of ultra-precision machining is higher than 0.1μm‌. ‌

Low surface roughness‌: The surface roughness of high precision machined parts is very low, which can reach Ra0.02~0.1μm or even lower, which means that the surface of the parts is very smooth‌. ‌

Widely used‌: High precision machining technology is widely used in aerospace, precision instruments, optics and laser technology, and can produce high-quality optical systems and other high precision parts‌. ‌

The realization of high precision machining depends on high precision machine tools and advanced machining technology. For example, ultra-precision turning technology can control the surface roughness within 0.01 microns, which is equivalent to the height difference between the peaks and valleys on the surface of the material being only at the nanometer level. In addition, the micro-nano processing center uses high precision and high-response linear motors and grating feedback systems to ensure precise positioning and stable operation during the processing, with an accuracy of 10nm to 100nm.
