摘要： A machine including two hollow members, each divided into two chambers with a diaphragm being the divider between the chambers, one of the chambers of each of the devices adapted to receive fluid to push the diaphragm in a direction to force abrasive material adapted to be held in the second chamber through an orifice extending outwardly from the second chamber, and a baffle positioned in the orifice to prevent expansion of the diaphragm through said orifice and to direct the flow of abrasive material into said second chamber when said hollow members are positioned to cooperatively move abrasive material through a workpiece held between the orifices of said members.

摘要： An abrasive medium is described consisting of finely divided abrasive particles uniformly distributed in a semifolid, difficulty flowable rubberlike plastic material of the consistency of putty and which forms a substantially solid matrix in carrying out the method of this invention which comprises forcing the medium over an internal surface in abrading contact therewith Representatives of such plastic material are silicone putty or silicone rubber and a nonvulcanized plastic rubberlike putty. Two forms of apparatus for carrying out the method are disclosed. The workpiece is held between two cylinders with an opening through the workpiece in communication with the adjacent cylinder chambers in which reciprocating pistons move the medium alternately from one cylinder through the workpiece opening into the other cylinder.

摘要： System for reduction of dimensional end-taper in abrasive blasted tubes has a pressurized chamber maintaining higher air pressure inside the chamber than atmospheric pressure, an air-exit port allowing gases to exit the chamber at a controlled rate, a valve restricting passage of gases from the air-exit port, a pressurized membrane through which the tube passes creating a seal, a gauge port where pressure inside the pressurized chamber is monitored and a media-exit port allowing evacuation of abrasive blast media particles after being expelled from the exit-end of the tube. The system addresses dimensional end-taper as high back pressure at the exit end of the tube reduces velocity of the gases and abrasive particles carried in it, thereby reducing erosion of the inner walls of the tube near its exit end. The system can be employed with a wide range of tube sizes and in combination with several abrasive blasting techniques.

摘要： An impeller manufacturing method includes: integrally forming an impeller by an additive manufacturing method using a metal powder, the impeller including a disk which has a disk shape about an axis, a plurality of blades which are formed on a surface facing a first side in an axial direction of the disk with gaps therebetween in a circumferential direction about the axis, and a cover which covers the plurality of blades from the first side in the axial direction; processing the integrally formed impeller by a hot isostatic pressing; and causing a polishing fluid containing abrasive grains to flow through a flow path formed between the disk, the cover, and the blades in the impeller after the processing with the hot isostatic pressing and while pressurizing the polishing fluid to perform fluid polishing.

摘要： A method for abrasive flow machining includes moving an abrasive media through a high-aspect passage of a workpiece. Local pressure of the abrasive media is increased at target abrasion surfaces of the high-aspect passage using a passage geometry that is configured to direct flow of the abrasive media into the target abrasion surfaces such that the target abrasion surfaces are preferentially polished by the abrasive media over other, non-targeted surfaces of the high-aspect passage at which the flow of the abrasive media is not directed into.
