Abrasive wheel abrasives break quickly, so they are recommended for grinding the work piece of low hardness and soft and abrasive wheels are recommended for work pieces of hard material.

The distribution of abrasives and bores. On the basis of structure grinding wheels are called dense or open grinding wheel. In case of dense grinding wheels abrasive partials are densely packed as compared to open. Generally, structure of grinding wheel is coded in number. Higher number indicates open structure of grinding wheel. Structure codes are given below. Structure Code a Dense structure 1 2 3 4 5 m 6 7 8 Open structure 9 10 11 12 a 13 14 Normally open structure wheels are recommended for rough grinding.

Dense structured grinding wheels are recommended for hard and brittle materials. Type of Bond u t Bond is the binding of abrasive particles together with the help of adhesive substance.

Different types of bond. S will be discussed later. Selection of a bond depends on the type of grinding operation; work piece material, required bond strength and contact area of work piece with the grinding wheel. This is to be defined and followed by the manufacturer for his own record. The various main elements of a grinding wheel are abrasive; bonds and structure which are described below. Abrasives 5 Page. Generally abrasive properties like hardness, toughness and resistance to fracture uniformly abrasives are classified into two principal groups: a Natural abrasives, and b Artificial abrasives.

Natural Abrasives There are a few examples of natural abrasives which include sa nd stone solid quartz ; emery; corundum and diamond. Diamond is not recommended to use as abrasive due to its cost in effectiveness. However, diamond dust which is the waste of diamond dressing operation can be used as abrasives. Natural abrasive are being described below. Sand stone is one of the natural abrasive used to make grinding stones. These are relatively soft.

These cannot be used for grinding of hard material and at faster speed. It consists impurities as remaining amount. Both emery and corundum are harder than quartz and can have better abrasive action. Normally natural abrasives are not preferred due to presence of larger impurities and lack of uniformly in constituents.

Artificial Abrasives m o Main artificial abrasive are silicon carbide and aluminum oxide. Artificial abrasive is preferred in manufacturing of grinding wheels because of their uniformity and purity. Artificial abrasives are described below.

Silicon Carbide. Sand furnishes silicon, cake. There are two types of silicon. It is less hard than diamond and less tough than aluminum oxide. It is used for grinding of n material of low tensile strength like cemented carbide, stone and ceramic, gray cast iron, brass, bronze, aluminum vulcanized rubber, etc.

Aluminum oxide is. S tough and fracture resistant. It is preferred for grinding of materials of higher tensile strengths like steel; high carbon and high speed steel and tough bronze.

Bonds A bond is an adhesive material used to held abrasive particles together; relatively stable that constitutes a grinding wheel. Vitrified Bond This bond consists of mixture of clay and water. Clay and abrasives are thoroughly mixed with water to make a uniform mixture. The mixture is molded to shape of a grinding wheel and dried up to take it out from mould.

Perfectly shaped wheel is heated in a kiln just like brick making. It this way clay vitrifies and fuses to form a porcelain or glass grains. High temperature also does annealing of abrasive. This wheel possesses a good strength and porosity to allow high stock removal with coal cutting. Disadvantage of this type of wheel are, it is sensitive for heat, water, oil and acids.

Their impact and bending strengths are also low. This bond is de oted s ol V i spe ifi atio. Silicate Bond Silicate bonds are made by mixing abrasive particles with silicate and soda or water glass. It is molded to. The raw molded wheel is baked in a furnace. These wheel exhibits water proofing properly so these can be used with oola t.

These heels a e de oted S i spe ifi atio. Shellac Bond. This bond exhibits greater elasticity than other bonds with appreciable. Grinding wheels having shellac bond are recommended for cool cutting on hardened steel and thin. This bond is de oted E i spe ifi atio s. What are differences between Up milling Down Milling b.
