Abstract
A subtle vortex polishing apparatus includes a receiving unit; a stirring unit, movably provided in the receiving unit; and a transmission unit, connected to the stirring unit. The workpiece to be polished and the fluid abrasive are placed in the in the receiving unit. The stirring unit is driven by the transmission unit so that the fluid abrasive in the receiving unit forms the eddy friction for polishing the workpiece and the deburring, polishing, chamfering for the workpiece can be finished in one time. Thereby, the grinding effect of the inner and outer surfaces of the workpiece enhances, and this invention can be thus used in processing small, bored, cracked, cambered complex surfaces, achieving the effects of easy operation, single-sided or multi-surface processing at the same time, increase in the processing rate, significant reduce in labor intensity, reduced processing costs and improved productivity.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
