Clarify
Your Requirement
We'll stay in close touch with you to deeply understand your requirements, provide expert recommendations, and ensure the ultra-precision optical components meet your technical and performance expectations.
Machining
Processing - CNC Machining
The CNC machining stage is crucial in shaping and setting the initial precision of optical components, laying the groundwork for later polishing and finishing. We conduct thorough inspections throughout and after the process to ensure all specifications are met.
Grinding
Processing - Grinding
Grinding involves using abrasives of varying grits to remove substantial material from the blank, approximating the final shape and reducing surface roughness. This crucial step ensures component precision and optical performance, requiring precise control over factors like abrasive type, pressure, and speed, setting the stage for subsequent polishing.
Polishing
Processing - Polishing Stage
We utilize a variety of advanced polishing techniques, including CCOS small tool polishing, robotic polishing, Ion Beam Figuring (IBF), and Magnetorheological Finishing (MRF). By integrating these sophisticated methods, we ensure our optical components achieve the ultra-precise surface accuracy required during the cold working process, meeting the stringent demands of high-end optical applications.
