Tool used is a abrasive wheel Grinding machine is a power operated machine tool where, the work piece is fed against constantly rotating abrasive wheel to remove thin layer of material from work. V
The Grinding Process Grinding is a material removal and surface generation process used to shape and finish components made of metals and other materials. The precision and surface finish obtained through grinding can be up to ten times better than with either turning or milling. Grinding employs an abrasive product, usually a rotating wheel brought into controlled contact with a work surface

Grinding wheel is a multipoint cutting tool having abrasive particals bonded together and so forming a structure. The various main elements of a grinding wheel are abrasive; bonds and structure which are described below. 2.4.1 Abrasives Generally abrasive properties like hardness, toughness and resistance to fracture uniformly abrasives are classified into two principal groups : (a) Natural
08.12.2016· That’s why we like to say that where machining ends, the centerless grinding process begins. For instance, if you have a part that is out of round from a turning machine and the part’s diameter is too small or its center is impossible to mount, you can achieve roundness through centerless grinding techniques. In addition, there is no axial thrust on the workpieces during the centerless

Below are parts produced with the through-feed centerless grinding process. As can be seen from the quantities produced, through-feed grinding is primarily a mass-production process because of its high throughput. In-Feed Grinding: In-feed grinding differs from through-feed grinding in that the part is not fed axially so that the ground surface does not need to be a right circular cylinder
Grinding Process: Mechanism of Grinding: In the grinding process, a layer of abrasive is responsible for removing the material from the work piece. As machining starts, the abrasives of grinding wheel and work piece comes into contact and due to the rubbing force the initial layer from the grinding wheel is worn out and a fresh layer of the abrasives involve in machining this process is
