Industry Knowledge ----Characteristics of Precision Cutting TechnologyPrecision cutting technology is an advanced manufacturing process aimed at achieving extremely high machining accuracy and surface quality, with its core characteristics centered around "micro cutting" and "precision control". Extremely high machining accuracy and surface quality: The goal of this technology is to achieve machining accuracy below 0.1 micrometers (μ m), with a surface roughness Ra value of 0.02-0.1 micrometers, and some ultra precision applications can even reach the nanometer level.
Relying on high-precision equipment and tools: The machining process must be carried out on ultra precision machine tools with high rigidity and stability, and equipped with specialized tools that have undergone fine grinding (such as single crystal diamond tools) to ensure nanoscale control of the motion trajectory. Micro cutting parameters: Using extremely small cutting depths (usually in the micrometer or even nanometer range) and extremely low feed rates, material is removed through a "thin layer cutting" method to avoid large stress impacts in traditional cutting. Strict environmental control: To ensure accuracy, processing is usually carried out in a dedicated environment with constant temperature (temperature fluctuation ≤± 0.1 ℃) and vibration isolation to eliminate the effects of thermal deformation and external vibration. Advanced process integration: Modern precision cutting integrates high-speed cutting optimization, thermal error compensation, on machine measurement, and intelligent feedback control technologies, which can correct machining errors in real time and improve consistency. Strong application orientation: This technology originated from cutting-edge fields such as aerospace and national defense, and has been widely used in optical components (such as non spherical mirrors), precision molds, aerospace components, medical devices, and consumer electronics that require high precision |
