    Nov 21, 2014· GRINDING MACHINE 3. Introduction • A grinding machine, often shortened to grinder, is any of various power tools or machine tools used for grinding, which is a type of machining using an abrasive wheel as the cutting tool. Each grain of abrasive on the wheel's surface cuts a small chip from the work piece via shear deformation.TYPES OF GRINDING WHEELS,Cylindrical grinding machine This machine is used to produce external cylindrical surface. Surfaces may be straight, tapered, steps or profiled. Broadly there are three different types of cylindrical grinding machine as follows: 1. Plain centre type cylindrical grinder 2. Universal cylindrical surface grinder 3. Centreless cylindrical surface

    Grinding Machine • Grinding is a metal removal process by the action of a rotating abrasive wheel. • An abrasive is a material whose particles are extremely hard and can be used to machine materials such as hardened steel, glass, carbides, ceramics, etc. • Grinding operation may be used for removing a thick layer (about 0.5 mm) of material in general class of work.MANUFACTURING PROCESSES,The main uses of grinding and abrasive machining 1. To improve the surface finish of a part manufactured by other processes. Examples: (a)A steel injection molding die is machined by milling. The surface finish must be improved for better plastic flow, either by manual grinding using shaped grinding tools, or by electro-grinding.
