Back End(BE) Process Wafer Back Grinding • The typical wafer supplied from 'wafer fab' is 600 to 750μm thick. • Wafer thinned down to the required thickness, 50um to 75um, by abrasive grinding wheel. › 1st step : Use a large grit to coarsely grind the wafer and remove the bulk of the excess wafer thickness.

Fine grinding or milling reduces the particle size down to as low as 1.0 micrometer (µm) (4 x 10-5in.) in diameter. Ball mills are the most commonly used piece of equipment for milling. However, vibratory mills, attrition mills, and fluid energy mills also are used. Crushing and grinding typically are dry processes; milling may be a wet or dry ...

The Manufacturing Process There are four major parts to a standard ball bearing: the outer race, the rolling balls, the inner race, and the cage. Races 1 Both races are made in almost the same way. Since they are both rings of steel, the process starts with steel tubing of an appropriate size.

Grinding (Rod) or (Ball) Mill TYPE D Has single weld, triple flanged, construction which means the shell is furnished in two sections, flanged and bolted in the center. All flanges are double welded as well as steel head to shell, note design. Tumbling Mill (Rod or Ball) Mill TYPE E Has quadruple flanged construction.

The production process of casting grinding balls: The casting grinding ball is a kind of grinding balls which uses the medium frequency electric furnace to melt the scrap steel, scrap iron and so on. The furnace charge is fully melted and the precious metal alloy (such as ferrochromium, Ferromanganese, ferrovanadium, etc.) is added to the furnace for chemical …

Manufacturing Process: Grinding Grinding, also called surface grinding, is a machining operation in which material is removed using a powered abrasive wheel, stone, belt, paste, sheet, compound, etc. to realize fine finish tolerances and surface finishes.

All Grinding Mill & Ball Mill Manufacturers understand the object of the grinding process is a mechanical reduction in size of crushable material. Grinding can be undertaken in many ways. The most common way for high capacity industrial purposes is to use a tumbling charge of grinding media in a rotating cylinder or drum.

Heat-treating: Carbon steel balls are next carburized and hardened. Heat treatment imparts the desired hardness and case depth. Descaling: This step removes the residues and by-products from the heat-treating process. Hard Grinding: Slow, meticulous grinding assures proper sizing and sphericity, with tolerances as close as ±.0001".
