1. The document describes a horizontal spindle and reciprocating table grinding machine. It includes diagrams of the machine and descriptions of its main parts and working. 2. The key parts are the grinding wheel, reciprocating work table, and various wheels for transverse, down, and cross feeds. The grinding wheel rotates horizontally to grind workpieces held on the reciprocating table. 3. The machine is used to grind metals with small widths and in medium-scale manufacturing industries such as for auto parts, taps, and aluminum shops. It allows hands-on workpiece holding and achieves high accuracy grinding.

4. Grinding Machime
• These machines are also known as machine
tools;
• It is used to obtain high accuracy with very
high class of surfae finish on the workpiece;
• Grinding machines are classified as:-
 Surface Grinding Machine,
 Cylindrical Grinding Machine,
 Internal Grinding Machine &
 Tool & Cutter Grinding
4

5. • Surface Grinding are further classified in the
following four types :-
i. Horizontal Spindle and Reciprocating table;
ii. Vertical Spindle and reciprocating table;
iii. Horizontal Spindle and Rotary table;
iv. Vertical Spindle and Rotary table.

8. Horizontal Spindle &
Reciprocating Table
• According to the name this grinder has a
horizontal spindle.
• A disc type grinding wheel which performs
the grinding action with its peripheral
surface.
• In this grinding machine the work piece can
be holded manually.

12. Functions of all parts of
machine:-
• Power control unit:-
• This unit is used to pass or allow the passage
of electricity in the grinding machine
12

13. Functions of all parts of
machine:-
• Head cross feed hand wheel :-
• This hand wheel allows the drilling wheel to
come in contact the work piece or the element
on which the work is done.
• This hand wheel is 2nd most important after
the power supply.
13

14. Functions of all parts of
machine:-
• Table transverse wheel and down feed
wheel:-
• This table transverse wheel is used to adjust
the place of the reciprocating table.
• The down feed wheel is used to feed the work
piece to the grinding wheel so that the work
piece omes in contact with the grinding wheel
and the work is done.
14

15. Functions of all parts of
machine:-
• Rotation of grinding wheel:-
• This grinding wheel is used to remove the
unwanted particles on the job, it is also used
to polish the job or to give a shining body as
well as to give a desired shape.
• The grinding wheel is decided on its speed
15

16. 16
Wheel Speed
• Majority operated most efficiently at 800
rotations per minute (rpm) to 1500 (rpm)
• Spindle speed varied for types and diameters
of wheels used.
– Speed varied by adjustment of pressure regulator

17. • Reciprocation of work-table:-
• It is the place where the job(object) is placed
which is being grinded.
• This table moves in reciprocating order on its
decided place.
17

18. Applications :-
• It is generally used for grinding the metals
with a small width.
• It is used in the industries with medium scale
of manufacture.
• It is used at the industries which are
polishing the auto-parts as well as this
grinding machines are used at the
productions of taps, aluminnium shops, etc,.
18

19. Applications :-
• It is also used at the industries for cleaning as
well as polishing the surface according to our
needs.

20. Working of a grinder
74-20

21. Advantages of this grinder
a) As this grinder is rotating in a horizontal
direction a work piece can be easily holded
by hands and the job can be done.
b) Due to its horizontal rotary motion the
surface area of the grinding wheel is less so
the minimum error can be corrected.
21

22. Disadvantages of this grinder
a) This grinder is less efficient as the area of
contraction is very less due to its horizontal
motion of the wheels.
b) This grinder is not used at a large extanct
with respect to that of vertical grinder.
