This has made the study of ultra-precise machining technology more and more important. After the inner wall of the hole is machined, burrs and the like are usually generated, so that the service life of the hole is influenced, and the quality of the wall surface of the hole is deteriorated. It is therefore necessary to polish the inner walls of the holes,

Thereby causing non-uniformity and non-completion of polishing.
The invention aims at the problems and provides a plunger hole rotary polishing device of a low-viscosity abrasive particle flow pump, abrasive particles are sprayed out through the wall surface of a polishing head by drilling holes on the wall surface of the polishing head through utilizing the centrifugal force of rotation and the pressure of extrusion of the abrasive particles, and the device has certain applicability through the reciprocating motion of the polishing head, so that the polishing of the plunger hole of the pump can achieve better and more uniform effects.
