Abrasive liquid slurry for polishing and radiusing a microhole

A system and method for radiusing and sizing microholes in diesel fuel injectors. A liquid abrasive slurry with rheological properties is used. As the slurry approaches and flows through the microhole, it is at first at a lower viscosity. Subsequently, the slurry is characterized by a high viscosity...

Beschreibung
Zusammenfassung:	A system and method for radiusing and sizing microholes in diesel fuel injectors. A liquid abrasive slurry with rheological properties is used. As the slurry approaches and flows through the microhole, it is at first at a lower viscosity. Subsequently, the slurry is characterized by a high viscosity which enables the use of a flow meter in the slurry flow path which directly and accurately monitors slurry flow rate and mass flow in real time. This allows for the individual slurry processing of nozzles to their specified flow rate in a continuous process.
