GRINDING (Abrasive machining) 
 Grinding is a surface finishing operation where very thin layer of material 
is removed in the form of fine dust particles. (thickness 0.25-0.5mm) 
 Grinding can be defined as a material removal process by the abrasive 
action between rotating abrasive wheel & the work piece. 
 Grinding machine is a power operated machine tool where, the work piece 
is fed against a constantly rotating abrasive wheel which is also called as 
Grinding wheel so that a thin layer of material is removed from the work 
piece.
PRINCIPLE OF GRINDING 
The work piece is fed against a constantly 
rotating abrasive wheel so that a thin layer 
of material is removed from the it. 
FIG. GRINDING
INTRODUCTION TO GRINDING PROCESS 
• It is the only economical method of cutting hard material like hardened 
steel. 
• It produces very smooth surface , suitable for bearing surface. 
• Surface pressure is minimum in grinding. It is suitable for light work,which 
will spring away from the cutting tool in the other machining processes.
GRINDING PROCESS
CLASSIFICATION OF GRINDING MACHINES 
Grinding machines are classified based on their 
construction & type of surface produced. 
1. Bench Grinding Machine 
2. Surface Grinding Machine 
3. Cylindrical Grinding Machine 
4. Centerless Grinding Machine 
5. Internal Grinding Machine 
6. Special Purpose Grinding Machine
1. SURFACE GRINDING MACHINE 
FIG. PRINCIPLE OF SURFACE GRINDING 
Principle: The work piece is fed 
against a constantly rotating abrasive 
wheel so that a thin layer of material 
is removed from the it. 
Work Piece Type: Flat, Angular & 
Irregular surfaces
SURFACE GRINDING MACHINE 
 This machine may be similar to a milling machine used mainly to grind flat surface. However, some 
types of surface grinders are also capable of producing contour surface with formed grinding wheel. 
 Basically there are four different types of surface grinding machines characterised by the movement 
of their tables and the orientation of grinding wheel spindles as follows: 
• Horizontal spindle and reciprocating table 
• Vertical spindle and reciprocating table 
• Horizontal spindle and rotary table 
• Vertical spindle and rotary table

CYLINDRICAL GRINDING MACHINE 
FIG. PRINCIPLE OF CYLINDRICAL 
GRINDING 
Principle: 
The work piece is held between two 
centers & and the rotating grinding 
wheel is fed against it. 
External Grinding machine 
Work Piece Type: Cylindrical surfaces 
may be straight, curved or contoured.
CYLINDRICAL GRINDING MACHINE 
 This machine is used to produce external cylindrical surface. The 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 grinder
Plain centre type cylindrical grinder
Universal cylindrical surface grinder 
 Universal cylindrical grinder is similar to a plain cylindrical one except that it 
is more versatile. In addition to small worktable swivel, this machine provides 
large swivel of head stock, wheel head slide and wheel head mount on the 
wheel head slide.
Special application of cylindrical grinder 
 Principle of cylindrical grinding is being used for thread grinding with 
specially formed wheel that matches the thread profile. A single ribbed wheel 
or a multi ribbed wheel can be used as shown in Fig. below.

Cylindrical Grinding Machine
CENTERLESS GRINDING MACHINE 
FIG. PRINCIPLE OF 
CENTERLESS GRINDING 
Principle: The work piece is placed on work rest 
blade between two wheels namely grinding & 
regulating wheel, which are rotating in clockwise & 
work piece rotates counter clockwise. Grinding 
wheel remove material from W/P surface & 
regulating wheel regulates the W/P. 
Centerless: Means work piece is not held between 
centers. 
Work Piece Type: Curved or Cylindrical surfaces 
of long slender rods which cannot be ground on 
cylindrical grinding.
Centre less Grinding
Centre less Grinding machine
External centreless grinder 
 This grinding machine is a production machine in which out side diameter of 
the workpiece is ground. The workpiece is not held between centres but by a 
work support blade. It is rotated by means of a regulating wheel and ground by 
the grinding wheel.
Internal grinding machine 
 This machine is used to produce internal cylindrical surface. The surface 
may be straight, tapered, grooved or profiled. 
 Broadly there are three different types of internal grinding machine as 
follows: 
1. Chucking type internal grinder 
2. Planetary internal grinder 
3. Centreless internal grinder
Chucking type internal grinder 
 The workpiece is usually mounted in a chuck. A magnetic face plate can also 
be used. A small grinding wheel performs the necessary grinding with its 
peripheral surface. Both transverse and plunge grinding can be carried out in 
this machine.
Planetary internal grinder 
 Planetary internal grinder is used where the workpiece is of irregular shape and 
can not be rotated conveniently as shown in Fig. below. In this machine the 
workpiece does not rotate. Instead, the grinding wheel orbits the axis of the 
hole in the workpiece.
Centreless internal grinder 
 This machine is used for grinding cylindrical and tapered holes in cylindrical 
parts (e.g. cylindrical liners, various bushings etc). The workpiece is rotated 
between supporting roll, pressure roll and regulating wheel and is ground by 
the grinding wheel.
