DISCO Dicing Saw Flange DFN-010000-0

In the spare parts system for DISCO dicing saws, the item FDFN-010000-0 is classified as a "flange" (often referred to in Chinese as a "blade holder" or "hub"). It is used at the end of the spindle to clamp and position the dicing blade.

Classification and Function

Within the spindle system of a dicing saw, the primary function of the flange (or hub) is to secure the cutting blade coaxially onto the high-speed rotating spindle, while ensuring precise radial runout and end-face accuracy. The flatness of the flange's end face directly impacts cutting quality; any degradation in precision—such as a deviation exceeding 2μm—can lead to issues like edge chipping or shifts in the cutting path. FDFN-010000-0 is categorized as a flange-type component within the DISCO spare parts catalog; some suppliers may refer to it as a "100-series flange."

As a precision-sensitive component, the flange requires the use of specialized tooling for installation, removal, and lapping (polishing), with strict controls maintained over the accuracy of its end face.
