The schematic diagram of ECG system is shown in Fig. 6.3. In ECG system, rotating conductive metal bonded abrasive grinding wheel acts as cathode and workpiece acts as anode in electrolytic cell. The wheel rotates at a surface speed of 20–35 m/s. Bonding materials are copper, brass, bronze, nickel or copper impregnated resin.
The external grinding principle is also applied to the internal grinding. In internal centreless grinding the work piece is supported by three rolls. One is the regulating roll, and the other is pressure roll to hold the work piece firmly against the support and the regulating rolls. This is illustrated in the diagram below.

Surface grinding machine. In this article, we will learn about the Working Principle and Operation Of Surface Grinding Machine. A Surface Grinding Machine is used for grinding flat surfaces. Also, concave-convex surfaces can be effectively grinding through. The surface grinding machine is classified as follows. a.
Grinding – Ex. 1-1 • You are grinding a steel, which has a specific grinding energy (u) of 35 W-s/mm3. • The grinding wheel rotates at 3600 rpm, has a diameter (D) of 150 mm, thickness (b) of 25 mm, and (c) 5 grains per mm2. The motor has a power of 2 kW. • The work piece moves (v) at 1.5 m/min. The chip thickness ratio (r) is 10.
The hydraulic circuit of the surface grinding machine utilizes a power pack to supply pressurized oil, one pilot-operated direction control valve which decides the direction of the flow of pressurized oil and a double-acting cylinder with the double piston rod.
Grinding Machine Parts and Functions. 6) Wheel Head :-It is the compartment that is moved vertically up or down using a traversing wheel called Vertical Feed Hand Wheel .We move this wheel head so that the grinding wheel can touch the workpiece. 7) Three types of traversing wheel :- i) Hand Traversing Wheel :- This traversing wheel is used to move the table …
Grinding machine is a type of machine tool and it is similar to other machine tools such as milling machine, turning machine, Lathe Machine and many more. The major difference between Grinding machine and other conventional machine tools is the type of operation and method of machining. Generally, all the machining process removes material …
Diagram of an engine lathe, ... •Similar to chucking machine except collet replaces chuck, permitting long bar stock to be fed through headstock •At the end of the machining cycle, a cutoff operation separates the new part •Highly automated (the term automatic bar machine is
One of them is called belt grinding. Belt grinding can replace the traditional grinding in the finishing operations. It uses a belt with abrasives in a grit range of 16–1500 and can rotate at different speeds. To avoid vibrations and to achieve highly accurate dimensions, belt grinding machines necessitate being rigid [2].
– A machine operation in which a work part is fed past a rotating cylindrical tool with multiple edges.
