UNION PROCESS INC. • 330.929.3333 • 4 of 10 Media sizes for attrition grinding range from 2.0 up to 25.0mm. Smaller grinding media generally result in faster particle size reduction because for a given volume there will be more impact and surface contact. As media become smaller than 2.0mm; mass is significantly reduced

Grinding process control balances these three interactions to achieve the desired parameters. These interactions feed into three major commercial grinding processes: rough grinding, precision grinding and ultra-precision grinding. Rough grinding maximizes the metal removed at the cost of surface finish. It primarily sees use in cutting off ...

Plunge grinding is also a discontinuous grinding process, in which machining is performed tooth by tooth. Both tooth flanks are machined simultaneously. There is a surface contact between tooth flank and grinding wheel. Due to the plunge movement of the grinding wheel in the axis direction, the grit path runs in parallel

For surface grinding operations, the process parameters, i.e. the linear feed, the cross feed, and the depth of cut, have a direct influence on the roughness of the ground surface.Higher values of any of them would result in a higher material removal rate, and therefore, a higher rate of generation of thermal energy.

Grinding is a material removal and surface generation process used to shape and finish components made of metals and other materials. Grinding employs an abrasive product, usually a rotating wheel brought into controlled contact with a work surface. The grinding wheel is composed of abrasive grains held together in a binder.
