Ingot Rounding. It is possible to round an ingot of compound materials or glass that thickness is around 30mm. Edge Grinding of Tiny Wafer. Edge grinding of wafers that diameter is less than 50mm such as lens cover is possible. ... Wafer edge can be mirror finished by the edge grinding process. Roughness of Ra = 20 nm is achieved (SiC).

Aluminium Ingot Grinder

The diameter of the ingot is controlled by the pulling rate and the melt temperature. Aluminium Ingot Ingot Trimming & Grinding Top and Bottom portions of the ingot are cut off and the ingot surface is ground to produce an exact diameter The ingot is also ground flat slightly along the length to get a reference plane. Reference plane

Silicon round grinding: formatting the ingot to cylinder with flat. As the diameter of the ingot from the furnace is not perfect, a round grinding step is needed to get a perfect cylinder, ready for making wafers with the right dimensions. During this step, a major flat is made in order to specify the orientation.
