growth of silicon ingots. A sequence of processes is required to turn an ingot into wafers. Some typical processes are listed below [3–5]. (1) Slicing—slice silicon ingots into wafers of thin disk shape; (2) Flattening (lapping or grinding)—achieve higher degree of ﬂatness on the wafers; (3) Etching—chemically remove the damage induced by
During the process of calibration - diameter of ingot is reworking according to the PO's specification of the costumer. Processing of diameter is made on OD machines with intuitive and program control and carried out by diamond grinding wheels of straight section. Surface purity is achieved as Ra 1µm and accurancy till 0.03mm.

1. The above billet grinding machines are suitable for the grinding of square billets, rectangular billets, forgings, round billets and steel ingots of different specifications. The entire unit is designed and manufactured in accordance with the actual requirements of the user.
FINISHING SPECIALISTS : Surface condition is a central requirement for many of our customers. To meet the requirements, we offer local grinding, bleaching (no fire zone), grinding down surface defects, finishes up to roughness < 6.3 Ra. To do this, we develop complete finishing solutions (from start to finish) for the softest grades to the hardest, and whatever the formats may be.
Mirror finish edge grinding of Ra = 20 nm is achieved by our helical grinding technology. Ingot Rounding It is possible to round an ingot of compound materials or glass that thickness is around 30mm.
