It is used to manufacture extremely precise optical and mechanical components. Ultra-precision grinding typically involves the use of special grinding machines and grinding wheels to achieve sub-micron surface accuracy.
Grinding machine tools with advanced CNC technology can achieve higher automation, precision, and controllability.
Advanced coolant and lubricant technology help increase grinding efficiency, lower temperatures, reduce friction, and help prevent thermal damage to material surfaces.
Various Polishing Methods, Diverse Optic Needs
Conventional Polishing
Yudi Optics uses asphalt technology for high-precision spherical and flat polishing of optical crystals, optical glass, and fused quartz. “Conventional Pitch Polishing” is a traditional polishing technique in optical processing, usually using a material called “pitch” as a grinding tool. This method is also known as “pitch polishing”. During the polishing process, abrasive material (usually abrasive fluid or abrasive particles) is added to the pitch surface. These particles roll over the pitch surface, grinding the workpiece surface at the same time. This process provides excellent surface shape and surface quality. We currently have a large range of continuous single-sided polishing rings available in different sizes to accommodate the optical polishing of substrates from 3mm to 1000mm.
CNC Polishing
Leveraging CNC polishing technology, Yudi excels in rapid mass production while seamlessly integrating intricate designs, superior precision, and cost-effectiveness.It has been the most widely used in common optic production.
IBF Polishing
Unlike mechanical polishing, ion beam figuring polishing is a contactless process. Before processing, surface errors are measured, and the ion beam etching system tailors a unique dwell time map for each substrate based on this profile. Using ions to bombard optical surfaces, it achieves nanoscale precision, making it ideal for polishing optics with diameters up to thousands of millimeters. While it requires a vacuum and has low material removal rates, it’s the final step at Yudi for precision processing. This breakthrough method allows us to create symmetrical, aspherical, or free-form optics, providing process flexibility, shorter production times, and superior quality.
Robotic Polishing
Yudi leads the trend of advanced technology and independently develops robot polishing technology. The ultra-precision polishing machine (IRP) is equipped with an intelligent system to automatically achieve high-precision polishing, significantly improving efficiency and achieving sub-micron-level surface accuracy for manufacturing more complex optical components.
MRF Polishing
Yudi Optics offers advanced Magnetorheological Finishing (MRF) for precise optical polishing, achieving nanometer-level surface quality and accuracy. This technology uses a magnetic fluid under computer control, making it ideal for polishing complex shapes and various materials, such as quartz and sapphire. MRF ensures high efficiency and quality, catering to demanding industries like aerospace and defense.
