01 Principle of Diamond Dicing Blade for DFN
The Diamond dicing blade is mounted on the soft blade flange of the cutting equipment's spindle. Under high-speed rotation of the spindle at RPM 20,000 to 30,000, the workpiece to be cut are broken by fracturing way and the chip pocket to remove the chips in time to ensure the processing quality.
