The core purpose of ultra precision lathes is to achieve ultra high precision machining at the micrometer (μ m) or even nanometer (nm) level, mainly serving manufacturing fields with extreme requirements for part size, shape, and surface quality.
Its machining accuracy far exceeds that of ordinary precision lathes, not only ensuring extremely small dimensional tolerances of parts (usually less than 5 μ m), but also achieving extremely low surface roughness (usually Ra value less than 0.02 μ m), making it a key equipment for manufacturing core components of equipment.
Main application areas and purposes
1. Aerospace field
Processing engine core components, such as turbine blade roots and precision mating surfaces of shaft components. These parts need to work stably in high temperature and high pressure environments, and their dimensional accuracy and surface quality directly affect the thrust and lifespan of the engine.
Manufacturing key components in inertial navigation systems, such as gyroscope rotors. This component has high requirements for roundness and cylindricity, and even small errors can lead to a significant decrease in navigation accuracy.
2. Optics and Optoelectronics
Processing optical lenses and molds, such as camera lenses and laser resonant cavity lenses. Ultra precision lathes can achieve ultra-high smoothness on the surface of lenses, reduce light reflection and scattering, and improve optical performance.
Manufacturing the core components of photoelectric sensors, such as the substrate of infrared detectors and the precision stage of semiconductor chips. The flatness and dimensional accuracy of these components directly determine the sensitivity of the sensor.
3. Medical device field
Processing minimally invasive surgical instruments, such as precision catheters for laparoscopy and threaded parts for dental implants. Ultra small dimensional tolerances and smooth surfaces can reduce surgical trauma and lower the risk of infection.
The key components for manufacturing medical imaging equipment, such as the rotating shaft of CT machines and the precision coil skeleton of MRI equipment. The high precision of these parts ensures the stability of equipment operation and image clarity.
4. Precision instruments and metrology field
The core components of precision machining instruments, such as the guide rails of coordinate measuring machines and the tooth surfaces of precision gears. Ultra precision machining can reduce component wear and ensure the accuracy of long-term instrument operation.
Manufacturing standard measuring components, such as micrometer sized measuring blocks and standard lead screws. These standard components need to have high dimensional accuracy for calibrating other measuring tools.
5. Automotive parts field
Processing precision gears for motor rotors and gearboxes of new energy vehicles. Ultra precision machining can reduce the friction loss of parts, improve motor efficiency and gearbox shifting smoothness.
The core components for manufacturing automotive sensors, such as the diaphragm of pressure sensors and the precision shaft of position sensors. The accuracy of these components directly affects the handling and safety of the car.
Core processing characteristics (key capabilities that support their use)
Ultra high precision: The dimensional tolerance of the parts can be controlled within 1-5 μ m, and the shape error (such as roundness and cylindricity) is less than 1 μ m, meeting the requirement of approaching "zero error".
Ultra smooth surface: The surface roughness of the processed parts can be as low as Ra0.005-0.02 μ m, and can be used directly without subsequent polishing, avoiding the damage to accuracy caused by secondary processing.
Stable machining consistency: Equipped with high-precision spindle, guide rail, and CNC system, it can ensure minimal accuracy differences for each part in batch production, suitable for batch manufacturing needs.
