Abstract
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 a first lower viscosity. Subsequently, the slurry is characterized by a higher viscosity which enables the use of a floor meter in the slurry flow path which directly and accurately monitors slurry flow rate and mass flow in real time. This allows for individual slurry processing of nozzles to their specified flow race in a continuous process.
