Naniwa Dup 09 Ccd E- - 18 [updated] Link

A new CCD wheel may require dressing to expose fresh diamond. Use a Naniwa dressing stick (e.g., NANIWA #600 silicon carbide). Do not use a single-point diamond dresser, as it will strip the grit.

CCD bonds perform best with a light water-based synthetic fluid (5-8% concentration). For dry grinding, reduce feed rate by 40% and use air blast.

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. NANIWA DUP 09 CCD E- - 18

A: In Naniwa’s coding system, dashes often indicate a "standard concentration" (C100) and a "standard shape" (Type 1A – cylindrical). The E may denote an economy bond with 25% less diamond for lower-cost applications.

At first glance, the alphanumeric string looks like an encrypted sequence—perhaps a military spec or a forgotten engineering prototype. However, for insiders in the abrasive technology and surface finishing industry, this code represents a specific, high-performance tool from one of Japan’s most respected manufacturers: Naniwa Abrasive Mfg. Co., Ltd. A new CCD wheel may require dressing to expose fresh diamond

A: If your process involves a rough cut followed immediately by a finishing pass without changing tools, the DUP design saves 30% cycle time. For single-operation grinding, a standard NANIWA CCD 09 is more cost-effective. Conclusion: Precision Without Compromise The NANIWA DUP 09 CCD E- - 18 is more than a product code—it is a statement of intent. It signals that the user demands Japanese precision, ceramic-diamond hybrid technology, and the efficiency of a duplex design in a compact 18mm form factor.

If max RPM is 25,000, calculate surface speed: Surface Speed = (π × OD × RPM) / 1000 For 18mm @ 25,000 RPM → ~1,413 m/min — ideal for glass and carbide. CCD bonds perform best with a light water-based

It is built for micron-level precision . The combination of the DUP (dual-use) configuration and CCD (ceramic composite diamond) bond targets four specific industries: 1. Semiconductor Die Backgrinding The "09" and "18" sizes align perfectly with wafer handling equipment. The diamond grains in the CCD bond provide fracture-free grinding of silicon, gallium arsenide, and other fragile semiconductors. The duplex nature allows a single mount to rough-grind to thickness, then finish with a finer grit. 2. Optical Lens Tooling (CCD Cameras) Ironically, the "CCD" in the product name correlates with its use: grinding glass and sapphire for CCD camera sensors, lenses, and protective windows. The 18mm wheel fits into precision optical grinders (e.g., Satisloh, OptoTech) for edge rounding and plano-finishing. 3. Carbide and Ceramic Die Molding For injection molding machine nozzles, extrusion dies, and ceramic ferrule manufacturing, the NANIWA DUP 09 CCD E- - 18 provides superior surface finish on tungsten carbide (HRa 92+) without burning. The E- - elastic bond absorbs vibration, preventing chipping on intricate micro-features. 4. High-End Woodworking (Tungsten Carbide Tip Sharpening) While less common, some master woodworkers use diamond DUP wheels to sharpen carbide-tipped saw blades and router bits. The 18mm diameter allows access into gullets between teeth. The "CCD" bond runs cooler than electroplated wheels, preserving the temper of the steel body.
