A grinding machine or grinder is an industrial power tool that uses an abrasive wheel for cutting or removing the m aterial. It is a process of metal cutting by using a rotating abrasive whee l from the surface of the workpiece. Generally, the grinding is finishing operation to show the high surface quality, accuracy of the shape and dimension.

These operations are used where highly accurate dressing of grinding wheel and grinding operation is not desired. Also, the operations are carried at the operating speed of the wheel and cannot be used to generate complex profiles on the surface. They are widely used and are inexpensive when compared

Grinding wheels achieved their ubiquity due to their speed, form repeatability and ability to achieve desired finishes. When selecting a wheel, it is important to determine whether the application requires rapid stock removal or a fine finish. Equally important is whether the part will be simple and flat, or if there is a form to hold.

Resinoid wheels are used for grinding speeds up to 16,500 SFPM. Their main use is in rough grinding and cut-off operations. Silicate bond. This bonding material is used when heat generated by grinding must be kept to a minimum. Silicate bonding material releases the abrasive grains more readily than other types of bonding agents.

In cylindrical grinding operation, the work is mounted between two centres and is rotated. A grinding wheel is mounted on a spindle and revolves at much higher r.p.m. than the work. The work centres are mounted on a table which can traverse at various feeds so that the entire length of the work passes to and fro in front of the wheel. The depth ...

Centerless grinding operation: This type of grinding operation, two grinding wheels are fitted parallel with a 5-10-degree angle which is provided to obtain a longitudinal motion of the workpiece. A cylinder rod is placed between the two-grinding wheel due to the tilted angle. This allows the workpiece to automatically pass through the wheels ...

Cylindrical grinding operations resemble lathe-turning operations. They replace the lathe when the workpiece is hardened or when extreme accuracy and superior finish are required. As the workpiece revolves, the grinding wheel, rotating much faster in the opposite direction, is brought into contact with the part.

The major injury risk in the use of grinding wheels is that the wheel may burst during grinding. Normally, grinding wheels operate at high speeds. There is a trend towards ever-increasing speeds. Most industrialized nations have regulations limiting the maximum speeds at which the various types of grinding wheels may be run.

Grinding wheels wear unevenly under most general grinding operations due to uneven pressure applied to the face of the wheel when it cuts. Also, when the proper wheel has not been used for certain operations, the wheel may become charged with metal particles, or the abrasive grain may become dull before it is broken loose from the wheel bond.
