GRINDING MACHINES Conventional grinding machines can be broadly classified as: (a) Surface grinding machine (b) Cylindrical grinding machine (c) Internal grinding machine (d) Tool and cutter grinding machine HORIZONTAL GRINDING CYLINDRICAL GRINDING SURFACE GRINDING CENRELESS GRINDING Surface grinding machine Machine may be similar to a milling machine used mainly to grind flat surface Basically there are four different types of surface grinding machines characterized by the movement of their tables and the orientation of grinding wheel spindles • Horizontal spindle and reciprocating table • Vertical spindle and reciprocating table • Horizontal spindle and rotary table • Vertical spindle and rotary table Horizontal spindle reciprocating table surfacegrinder Surface grinding (a) traverse grinding (b)plunge grinding Vertical spindle reciprocatingtable surface grinder Surface grinding in Vertical spindle reciprocating table surface grinder Cylindrical grinding machine This machine is used to produce external cylindricalsurface.Surfaces may be straight, tapered, steps or profiled.Broadly there are three different types of cylindricalgrinding machine as follows: 1.Plain centre type cylindrical grinder 2.Universal cylindrical surface grinder 3.Centreless cylindrical surface grinder Plain centre type cylindrical grinder TYPES OF GRINDING WHEELS Straight Wheel These are generally used for cylindrical, internal, centreless and surface gri ...
