Our 5-Axis Grinder has been optimized to achieve very tight tolerances and repeatability across its entire 20 meter2 working footprint. Rayotek can precision grind large ceramic, glass, fused silica and glass ceramics to any shape with the 5-Axis Grinding System including OD grinding ceramic and glass up to 4 meters in diameter. Rayotek can also perform large optics grinding and large surface grinding on this system.
Machine enhancements include:
- Fanuc control & drives
- Renishaw touch probe for in-process adjustment of tool path
- Onsite laser mapping for higher accuracy
- Temperature controlled work environment
In addition, Rayotek has the capability to anneal large workpieces. Annealing is often required before and/or after grinding to insure higher accuracy and stability of the final product; especially after large surface grinding and large optics grinding.
Fusing & Bonding:
Rayotek can fuse similar and dissimilar materials to form solid, stable large blanks that can be molded and/or ground to precision shapes. Rayotek bonding technologies are often stronger and more stable than the materials being bonded.
Rayotek bonding methods:
- Thermal fusing
- Controlled atmosphere brazing & soldering
- Permanent high strength adhesive bonding
CMM for Large Formats:
Rayotek has a massive CMM to support its large workpiece grinding and molding capabilities. Our large CMM can measure workpieces up to 4.5meters x 1.7meters x 0.7meters in a temperature controlled environment. All of our large grinding and large molding can be inspected and certified on our massive CMM including our large optics grinding and our large surface grinding.
Rayotek Staff Expertise:
Molding, shaping and grinding of large size workpieces is a unique skillset achieved only through years of experience and an ongoing commitment to continuous R&D and improvement. With a team of engineers and scientists committed to excellence, Rayotek has the capabilities to work with customers for optimized design and processing strategies.
Applications for large workpiece shaping:
• Massive Optics & Large Reflectors - for telescopes & aerospace
• Molds - for metal & superplastic forming
• Composite Molds - ceramic & glass
• Precision Domes - for deep sea vehicles & aerospace
• Supports & Holders - thermally stable, fused quartz & ceramic
• Mounts - for large turrets
• Models – scale size for prototyping & testing
• Large Scale Prototypes - for testing Lithography Stages &
Bases - made of low CTE materials, such as: glass ceramic,
fused silica & borosilicate
DelCAM Software Support:
DelCAM is the premier CADCAM software for machining and grinding complex curved shapes. DelCAM is specifically designed for shaping curved surfaces where tool path patterning and mesh faceting is undesirable. Using DelCam software we can generate G-code to achieve near perfect surfaces.
