Types of Grinding Machine - mech4study. The grinding is a simple process in which very small size of chips are remove from work piece by rubbing action of an abrasive material. But at different condition according to the working environment, different types of grinding machines is used. Types of Grinding .
Grinding is an operation applied in almost every type of manufacturing process. It aims to produce high surface finish and to maintain close tolerances in the manufactured product. To make the grinding operation more productive and efficient, dressing and truing operations are performed on the grinding .
Fig. Types of surface grinding machines Tool and cutter grinder In grinding tools by hand a bench or pedastal type of grinder is used. The tool is hand held and moved across the face of the wheel continually to avoid excessive grinding in one spot. For sharpening miscellananeus cutters a universal type grinder is used. 2. Types of Grinding wheels

Grinding: Grinding is a process of removing material by abrasive action of a revolving wheel on the surface of a work-piece in order to bring it to required shape and size The wheel used for performing the grinding operation is known as grinding wheel It consists of sharp crystal called abrasive held together by a binding material or bond The wheel may be a single piece or solid type or may be ...
cutting edges. The machine on which grinding the operation is performed is called a grinding machine. Grinding is done to obtain very high dimensional accuracy and better appearance. The accuracy of grinding process is 0.000025mm. The amount of material removed from the work is very less. 4.2 Types of grinding machines
Regardless of the type of machining operation, some basic types of chips or combinations of these are found in practice (Fig. 13.4.4). Continuous chipsare formed by continuous deformation of the work-piece material ahead of the tool, followed by smooth flow of the chip along the tool face. These chips ordinarily are obtained in cutting duc-
