Grinding Machine: Types, Parts, Working & Operations

Working principle of Grinding Machine: The working principle of a grinding machine is quite easier to understand In a grinding machine, there is an electric motor which supplies the motion power to the grinding wheel with the help of a belt and pulley So when we start the electric motor the motor rotates at a certain rpm (15015000 RPM, it may change according to the types of grindingBoring is performed on the inside diameter of an existing hole Turning is performed on the outside diameter of an existing cylinder •In effect, boring is an internal turning operation •Boring machines Horizontal or vertical refers to the orientation of the axis of rotation of machine spindleMACHINING OPERATIONS AND MACHINE TOOLSThe Shaper Machine tool used for shaping operation is called shaper Designed for machining flat surfaces on small sized jobsIf the size of the job is large, then planing isused In a shaper , the work piece is held stationary during cutting, while the tool reciprocates horizontally the feed and depth of cut are normally provided by moving the workShaping, Planing and Slotting Operations
