32. GRINDING MACHINE

33. WHAT IS GRINDING MACHINE?
A grinding machine is such type of machining using
an abrasive wheel as the cutting tool .It is used to
finish the work piece that must show high surface
quality.

41. AREA OF APPLICATION:
 Machining flat surfaces in different planes. Flat
surfaces are produced by single point cutting tools
in horizontal, vertical and inclined planes.
 Making features like slot, steps etc. which are also
bounded by flat surfaces.
 Forming grooves bounded by short width curved
surfaces by using single point but form tools.

cutting external keyways and splines, smooth
slitting or parting, cutting teeth of rack for repair etc.

critical work like helical grooving on large rods and
wide 2-D curved surfaces etc. can also be made if
needed.

Gear is one of the machine tool elements which is an
integral and inevitable part of power transmission
system.
