The bonding material does not cut during the grinding operations. Its main function is to hold the grains together with varying degrees of strength. The different standard grinding wheel bonds are vitrified, resinoid, silicate, shellac, rubber, and metallic. Factors affecting the selection of Grinding wheels:
Abrasive grains are held together in a grinding wheel by a bonding material. The bonding material does not cut during grinding operation. Its main function is to hold the grains together with varying degrees of strength. Standard grinding wheel bonds are vitrified, resinoid, silicate, shellac, rubber and metal. Vitrified bond.
Types of bond in grinding wheel Bonding materials used for making the wheel is given below •Vitrified Bond •Silicate Bond •Shellac bond •Resin or Resinoid Bond •Rubber Bond •Metal Bond •Oxychloride Bond •Reinforced Resin Bond Vitrified Bond Its main constituent is felspar, which is mixed with some other refractory material to form a strong bond.
The amounts of each of these grinding wheel components can be adjusted as needed for a given application, and together make up a complex and functional composite intended to produce surfaces of interest. Figure 1. This schematic shows grinding wheel structure, showing abrasive grain, bond, porosity, and filler components.
The bond of grinding wheel is for the purpose of holding the abrasive grains of cutting edges. It is also to withstand a grinding force and rotary stress and simultaneously need characters to generate the abrasive grains adequately in accordance with the increase of grinding force by abrasive grain wear.
Grinding wheels having shellac bond are recommended for cool cutting on hardened steel and thin sections, finishing of chilled iron, cast iron, steel rolls, hardened steel cams and aluminium pistons. This bond is denoted by 'E'in specifications. Resinoid Bond
A grinding wheel is basically a precision tool composed of abrasive grains held together by a bonding material. The abrasive grains provide the wheel with its cutting ability which helps in finishing the material to the required dimensional accuracy and surface finish.
Grinding wheel bond types: A bond is an abrasive material used to held abrasive particles together. The bonding material does not cut during the grinding operations. Its main function is to hold the grains together with varying degrees of strength.
A grinding wheel is a combination of CBN particles wrapped with a coating and then embedded in a bonding material (or bond). The bond of a CBN wheel is one of the most important factors when choosing the correct wheel for the job.
Super-hard grinding wheels (including diamond and CBN grinding wheels), the main bonding agents include Metal, resin, vitrified, electroplated and brazed bonding agent etc. Conventional grinding wheels (including aluminum oxide and silicon carbide grinding wheels), the main bonding agents are vitrified, resin and rubber, etc.
One example of a recent bond development for precision grinding wheels is Norton Vitrium bond. Designed to be stronger than conventional vitrified bonds, Vitrium bonded products are capable of higher operating speed ratings and have a lower overall bond content for a given degree of abrasive holding power.

What is Grinding? Grinding is a machining process improving the surface finish of the job and producing small chips. The tool used for this process is the grinding wheel. It is a cutting tool in which millions of microscopic abrasive grains are bond together. Here, each abrasive grain acts like a spiky tool.
Proper grinding wheel selection is essential to ensure that the required part quality, production rate, and overall cost per part is achieved. Although the type of abrasive grain is often a primary driver of wheel selection, the bonding type can also play a key role in optimizing a grinding operation. As technical demands on production continue ...
A - It is denoted the type of abrasive where "A" means aluminium oxide. 46 – It is denoted the grain size of grinding wheel where "46" represent medium size. N – It is defined grade of grinding wheel where "N" represent medium grade. BF – It is defined bonding materials of grinding wheel where "BF" represent reinforced ...
Grinding, or abrasive machining, is the process of removing metal in the form of minute chips by the action of irregularly shaped abrasive particles. These particles may be in bonded wheels, coated belts, or simply loose. Grinding wheels are composed of thousands of small abrasive grains held together by a bonding material.
Grinding wheels, regardless of their manufacturer, are made up of three main components: An Abrasive Grain. Aluminum oxide, silicon carbide, zirconia, ceramic alumina, cBN, or diamond are the most common. A Bonding Agent. Vitrified – glass-like bond. Organic – resin or other agent. Air/Empty Space.
Bond Selection for Production Grinding. Proper grinding wheel selection is essential to ensure that the required part quality, production rate, and overall cost per part is achieved. Although the type of abrasive grain is often a primary driver of wheel selection, the bonding type can also play a key role in optimizing a grinding operation.
2.2 Types of vitrified bond. There are many classification principles for the vitrified bond, mainly introducing the following: 2.2.1 There are fused bond, sintered bond, semi-fused (semi-sintered)bond according to the relationship between the firing temperature of the grinding wheel and the refractoriness of the bond.
Bond is a material that combines abrasive grains together, which forms an abrasive layer of different shapes. The hardness of the grinding wheel what we call is actually the bonding strength. Super-hard grinding wheels (including diamond and CBN grinding wheels), the main bonding agents include Metal, resin, vitrified, electroplated and brazed ...
