2. INTRODUCTION
• Any machine which is used for mass production of
particular component is called Special Purpose machine.
• SPM tools are developed for performing specific
operation in mass production environment.
• SPM intended for manufacture of a special type of
product.
• The machine will not have much variation but will have a
small with in that vacinity.
• Ex. Hexagonal nuts, springs are some of the examples
of product which are manufacture with the help of special
purpose machines.
3. Facing and centering machines
Used to provide accurate center and face reference for
further operations like turning and grinding, facing and
centering machines come in both vertical and horizontal
configurations with slide for plunge milling or traverse milling.
• Cam lob milling
• Profile milling
• Keyway milling
• Groove milling
• Slot milling
Cylindrical Grinding Machines are versatile and reliable and
have started a revolution of accuracy and advanced
automation across the globe.
Then emerged a unique range of sophisticated cylindrical
grinders with unmatched levels of precision and efficiency.
5. Special vertical turning machines:
From simple turning to more demanding turn-milling
complex 5-face machining, this range cover all
applications. Available in four capacities-
500,850,1250 and 1250+, special vertical turning
machines are designed in three configurations to
suit specific requirement-
• VT- turning machines
• VM- multi tasking turn-mill machines
• VU- 5-axis universal turn-mill machines.

7. Multi operation, Multi station, Rotary table
machine
These rotary machines are designed for the simultaneous
execution of multiple operations like drilling, tapping,
rough boring, fine boring spot facing and reaming and
can usually be handled by one operators.This offers the
benefit of the best possible productivity and cycle time.
8. Special purpose machine tools for metal
cutting
• The machines describes below cannot be fitted into the
classification of conventional metal cutting machine tools
owing to the arrangement or the type of their cutting
tools.
• Combined planning and grinding machine for the
production of corrugating rollers for the manufacture of
corrugated paper.Index-table machines for the
production of rear-axle housing.
