Tomatic grinding, which could be important when the cross section at a speciﬁc depth is of interest. Automatic equipment is much expensive than manual machines. Diamond abrasives are recommended for grinding most ceramics, but silicon carbide (SiC) paper and cubic boron nitride (CBN) platens can also be used.
Dec 23, 2018 Grinding machine is a type of machine tool and it is similar to other machine tools such as milling machine, The steel is machined by using Aluminum oxide over the silicon carbide because Aluminum oxide is tougher than the silicon carbide so it is preferably used to machine steel having higher tensile strength. over Aluminum oxide has.
Grinding wheels Grinding wheels can sharpen knives and tools Grinding wheels are produced by mixing the appropriate grain size of abrasive with required bond and then pressed into shape The characteristics of the grinding wheel depends on number of variables Specified by dia. of wheel, dia. of spindle hole and face width of wheel.

Fig. 15 Grinding, sawing, etching and polished (from left to right) are the work steps from an ingot to a ﬁ nished wafer Fig. 16 The usual ( SEMI-standard ) arrangement of the ﬂ ats with wafers in de-pendency on crystal orientation and doping Fig. 17 Diagram of an inside hole saw with the centrally mounted silicon ingot Inside Hole Saw.
The abrasive itself depends on the material to be ground. For soft materials, this is essentially silicon carbide (SiC) as paper, foil, grinding disc or grinding stone. For harder materials ( 300 HV, e. g. hardened steel or ceramics), diamond grinding discs are however used. These are usually fixed on a magnetic carrier disc.
Silicon carbide, SIC, with a hardness of about 2,500 HV, is a widely used abrasive for grinding papers for mainly non-ferrous metals. Aluminium oxide, with a hardness of about 2,000 HV, is primarily used as an abrasive in grinding stones.
