What is Precision Manufacturing?
Precision manufacturing is a manufacturing technology that focuses on extremely high precision, small tolerances and strict quality control, and aims to produce parts or products that meet extreme requirements in size, shape and performance.
According to the master of Foshan Ruizheng Machinery Factory, its core lies in achieving micron-level (μm) or even nanometer-level (nm) precision control through advanced processes, equipment and materials, and is widely used in high-tech fields.
Precision Manufacturing Core Features
Ultra-High Precision: Tolerances as tight as micrometers (e.g., nanometer-scale lithography in chip manufacturing).
Advanced Processes: Techniques like ultra-precision machining (e.g., diamond turning), photolithography (semiconductors), and laser processing.
Specialized Materials: Machining hard-to-process materials such as tungsten carbide, ceramics, and monocrystalline silicon.
Rigorous Quality Control: Real-time monitoring using coordinate measuring machines (CMM), optical inspection, and other metrology tools.
Examples of key technologies for precision manufacturing
Semiconductor Manufacturing: Extreme Ultraviolet (EUV) lithography for 7nm/5nm chips
Ultra-Precision Machine Tools: Air-bearing spindles with ≤0.1μm rotational accuracy
Additive Manufacturing: Metal 3D printing with 20μm layer thickness control
Microelectromechanical Systems (MEMS): Fabrication of micro-devices like accelerometers
Precision Manufacturing Application Areas
Aerospace: Turbine blade cooling holes (0.3mm±0.005mm diameter)
Medical Devices: Artificial joint surfaces with Ra≤0.05μm roughness
Optical Components: Laser mirrors with λ/10 surface accuracy (λ=632.8nm)
Automotive Industry: Micro-hole drilling in fuel injectors (0.1mm diameter)
Precision Manufacturing Trends
Hybrid Machining: Combining ultrasonic, laser, and other energy-based processes
Smart Compensation: AI-driven real-time error correction using industrial big data
Atomic-Scale Manufacturing: Techniques like scanning tunneling microscopy (STM) for single-atom manipulation
Precision manufacturing capability reflects a nation’s advanced equipment prowess. Examples like ASML’s 13nm-positioning-accuracy lithography machines or the Hubble Telescope’s λ/20 mirror finish demonstrate cutting-edge breakthroughs. With emerging fields like quantum technology and biomedicine, precision manufacturing is advancing toward sub-nanometer accuracy.
