In ultra-precision grinding, the situation is different . In fact, similar ultra-precision machining equipment is used for precision grinding, but the ideal grinding tool has not yet been invented. The surprising finding that grinding of brittle materials can produce optically smooth surfaces without sub-surface damage is explained by the phenomenon of …
Abstract A phenomenon commonly encountered in grinding of silicon wafers is the grinding marks, which are difficult to remove by subsequent polishing process, and have been a great obstacle to the manufacture of silicon wafers with higher flatness. In this paper, the grinding marks formation mechanism was clarified, a grinding marks formation model and an angular …

A grinding wheel is a wheel used for grinding. Grinding wheels are composed of abrasive compounds and are used for various grinding (abrasive cutting) and abrasive machining operations. Such wheels are used in grinding machines.. The wheels are generally made with composite material.This consists of coarse-particle aggregate pressed and bonded together by …

Silicon wafers are sliced from the ingot using both ID and Wire type saws. The ID saw can produce only single wafers at a time. The Wire saws are more efficient because we are able to slice the entire ingot at once. After the epoxy has cured, the ingot section is inverted and mounted into the 10-ton Wire saw.

Grinding and Polishing GRINDING removes saw marks and levels and cleans the specimen surface. Polishing removes the artifacts of grinding but very little stock. Grinding uses fixed abrasives—the abrasive particles are bonded to the paper or platen—for fast stock removal. Polishing uses free abrasives on
Grinding marks are regard as a great obstacle to manufacture spherical and aspheric surfaces with higher surface quality, lower energy and wastage. The scallop-height was studied for optimizing the grinding parameters firstly to reduce its effect on grinding marks. Secondly, the expression of grinding points distribution was established to characterize the …

Grinding marks on silicon wafers are caused by the axial run out of the cup wheel. Grinding marks present multiple angular wavelengths characteristics. A grinding marks formation model was developed. An angular wavelength model of the grinding marks was developed. Grinding marks can be suppressed by reducing the cutting paths aggregation.
