An improved dry barrel finishing machine is described, in which a mass consisting of media and workpieces is flowed in the barrel of the machine for abrasive finishing of the workpieces and in which air suction is used to remove dust res...
Dry media mass finishing processes can be used to produce refined edge and surface effects. These processes are not as well known as conventional processes that make use of aqueous solutions in concert with abrasive media. Although not u...
specimen.Barrel finishing with media for medium and final finishing after the medium finishing, performed using convention rotation grinding wheels, was found ...
The 2D kinetics of the workpiece during barrel finishing operation is studied. A particle image tracking technique was applied to a transparent thin barrel...
The speed-up of the disc rotation in dry centrifugal barrel finishing is done and its influence on finishing characteristics is experimentally examined. Th...
Corner shaping is a necessary operation in manufacturing of most mechanical components. Edge radiusing is the principal way to reduce stress concentration ...

This invention is addressed to mechanical finishing and media therefor wherein the finishing media are formed of geometric shapes of bauxite particles which have been sintered at a temperature within the range of 2,900 DEG -3,100 DEG F.
Cordierite ceramic honeycomb structural bodies having a high thermal shock resistance and a high water absorption are produced by adding the defined amount of starch powder, a binder and water to a ceramic starting material to crystalliz...
Substantially pore-free abrasive grit comprising zirconium oxide mixed with alumina or bauxite made by mixing the components together in molten form in the substantial absence of nitrogen.
A method of making sintered aluminous abrasives from uncalcined bauxite. The uncalcined bauxite is mixed with sulphuric acid and dissolved. This forms aluminum sulfate hydrate as a major product. The aluminum sulphate hydrate is then dr...
An improved pressure blasting product adapted for cleaning and peening operations in general but having a particular use in a method of shot peening objects made of aluminum. A substantially solid sphere of a refractory oxide material is...
A method of grinding a particulate material, comprising grinding said material in a stirred mill in the presence of a grinding media comprising rod-shaped particles, wherein said rod-shaped particles have an aspect ratio of equal to or g...
