| Specification | Probable Value | |---------------|----------------| | | Diamond or CBN Grinding Wheel / Mounted Point | | Outside Diameter (OD) | 18 mm | | Thickness (T) | 3 mm to 6 mm (depending on DUP variant) | | Arbor/Hole Size | 6 mm or 3 mm (common for precision tools) | | Grit Range | #400 to #3000 (likely medium #800 to #1200) | | Bond Type | Ceramic Composite Diamond (CCD) – Vitrified or Hybrid | | Concentration | 100% (Standard industrial use) – the dashes " - -" may indicate variable | | Max Operating Speed | 15,000 – 30,000 RPM | | Application | Dry or Wet grinding with coolant |
| Issue | Symptom | Probable Cause | Solution | | :--- | :--- | :--- | :--- | | | Machine pauses reporting "surface defect" when none exists | Slurry bubbles or dried slurry flakes on the platen | Increase slurry flow volume or adjust CCD threshold sensitivity via the "E" HMI. | | Carrier "E- - 18" Jamming | One of the 18 work carriers stops rotating; error code 18-07 | Worn carrier gear teeth or incorrect back pressure | Replace the polymer carrier ring. Check that pneumatic pressure does not exceed 12 psi. | | Thickness Variation | Parts from center carriers are thicker than edge carriers | Platen conditoning disc worn unevenly | Use the NANIWA auto-conditioning routine (30 min diamond disc run). | NANIWA DUP 09 CCD E- - 18
Whether you are backgrinding silicon wafers, polishing optical glass, or sharpening carbide dies, this tool offers a level of consistency that generic abrasives cannot match. While its nomenclature may seem cryptic, each alphanumeric element—NANIWA, DUP, 09, CCD, E- - , 18—tells a story of engineering excellence. | | Thickness Variation | Parts from center
You won't find the Naniwa DUP 09 CCD E- - 18 in a standard home workshop. This is industrial-grade equipment designed for the following demanding sectors: You won't find the Naniwa DUP 09 CCD
Whether you are producing next-generation LiDAR lenses, satellite-grade filters, or silicon carbide power wafers, this machine remains a worthwhile investment. It is not the cheapest machine on the market—nor is it the fastest. But for the engineer who understands that quality is not inspected into a part, but lapped into it , the NANIWA DUP 09 CCD E- - 18 is unparalleled.
