Product Description
General Introduction:
From prototype to high-volume production Raytek Optics is dedicated to manufacturing custom plano optics to meet your precise specifications. Since 2017, Raytek Optics has built a worldwide reputation in custom optics manufacturing pairing traditional craftsmanship with leading-edge technology. Our 50,000 sq. ft. facility houses the larger collection of cnc cutting machines,cnc milling machine centers, double-sided polishing machines,PIB polishing machine, MRF polishing machines, etc in Shanghai,China.
Custom Manufacturing Capacity 5: Double-sided Grinding & Polishing
Double-sided grinding and polishing, also known as double-sided lapping and polishing is performed with particles suspended in a liquid vehicle to abrade parts equally from both surfaces. The process produces a relatively stress-free environment that induces minimal thermal distortion making it compatible with most optical materials. The double-sided manufacturing process uses planetary action, with the combination of a top and bottom plate, resulting in outstanding transmitted wavefront error, parallelism, surface quality and surface roughness.
Raytek Optics provides ultra-precision double-side grinding & polishing for the exceptional Transmitted Wavefront Error, Total Thickness Variation, and Parallelism for sizes up to 800mm in diameter and thickness down to 0.10 mm
Raytek Optics is home to the larger collection of double-sided polishing machines in Shanghai,China. With over 40 state-of-the-art double-sided machines our manufacturing capabilities are endless. From prototype to production volumes, Raytek Optics will be there every step of the way. Raytek Optics double-sided polishing process produces parts with exceptional sub-second parallelism and fractional wavefront error.Raytek Optics technicians and engineers have perfected run-to-run consistency which make every part be the same batch after batch, year after year even with the most stringent requirements. Raytek Optics also can achieve a greater economy of scale by using a batch-processing method. So whether you need just a few parts, or tens of thousands, Raytek Optics will analyze the most efficient process to save you both time and money.
Main Processing Technical Capacity Data:
Main Cutting Technologies Advantages:
Polishing refers to the use of mechanical, chemical or electrochemical effects to reduce the surface roughness of the workpiece, in order to obtain bright, smooth surface processing method. Is the use of polishing tools and abrasive particles or other polishing media to modify the surface of the workpiece processing, with the following characteristics.
1).High parallelism of polishing;
2).It is especially suitable for cold working of large aspect ratio or thin components;
3).High quality polishing plane precision;
4).It is suitable for rough grinding, intermediate grinding, fine grinding and fine polishing;
5).High efficiency, high quality and stability, make every piece and batch of polishing quality consistent
