The greater the difference in speeds, the faster the removal rate. 4. The choice of grinding wheel is critical. Another key factor in centerless grinding is the choice of grinding wheel. It must be suited to both the metal from which the parts are made and …
Grinding is commonly used on cast iron and various types of steel. These materials lend themselves to grinding because they can be held by the magnetic chuck commonly used on grinding machines and do not melt into the cutting wheel, clogging it and preventing it from cutting.
Nowadays there are various types of material used for making of the grinding wheel. This depends on the usage of the grinding wheel. These are generally constructed out of sold steel and aluminum steel. The particle bonds with the help of the natural composite stones like that of millstones. How is the grinding wheel produced?
Ensure the proper wheel for the stock is being used. There are different grinding wheels for aluminum, stainless steel, and titanium. Clean the bed before placing the workpiece onto it. This will prevent interference with the magnetic chuck. Place magnetic parallels around the workpiece to ensure the workpiece does not shift during grinding.
On the other hand, very low grinding wheel speeds, in the order of 3,000 to 4,000 fpm (about 15 to 20 m/sec) are needed for the surface grinding of various types of high alloy and high strength work materials, using the lower wheel speed as a means for minimizing the development of heat, to which certain types of materials and workpieces are ...

Silicon Carbide (SiC) known in trade as Carborundum. Harder than Al2O3 but not as tough. Used to grind: aluminum, brass, stainless steel, cast irons, certain brittle ceramics
Sparks will fly off steel when put to a grinding wheel and each kind of steel produces a different color and volume of sparks. The volume of sparks depends on the carbon content. Wrought iron, which has very low carbon produces very few sparks. High carbon produces many sparks. Here are a few examples of what to look for when spark testing.
