What is planer machine , part's name , using tool and clamping device full details ?
WHAT IS PLANER MACHINE ?
(1) The planer machine is similar to the shaper machine . Primarily used to produce flat surface by a single point cutting tool
(2) Planer machine is capable of machine large and heavy workpiece which can not be machined by shaper machine .
(3) The planer is very large and heavy compare to shaper machine .
DIFFERENT PARTS OF THE PLANER MACHINE ?
The different parts of the planer are mentioned below :-
(1) Bed
(2) work table
(3) column
(4) crossrail
(5) saddle
(6) Tool head
FUNCTION OF THE DIFFERENT PART'S OF THE PLANER MACHINE ?
BED :
The bed of a planer must be a casting twice as long as the table .
The bed acts as a foundation of the machine .
The bed has accurately finished way on which the work table is slides .
WORK TABLE .
The work table is a heavy rectangular casting which carriages the heavy and long workpiece .
It travels on the flat ways of the bed .
The upper surface of the table has T slots in it to facilitates the clamping of the vices and fixture with the belt .
COLUMN
The frame of the planer has heavy column fastened at the top .
This creates very strong rigid structure which will handle heavy loads .
CROSSRAIL .
The Crossrail is a heavy box like structure .
It slides up and down on the flat ways controld by hand
The purpose of Crossrail is to carry the vertical tool head .
TOOL HEAD .
The tool head of the planer is similar to that of a shaper both in construction and operation .
The tool head is attached to the Shaddle which contains the tool post which holds the cutting tool .
WORKING OF TOOLS & TOOL SUPPORTS .
The cutting tool used in planer machine are single point cutting tool .
The planer tool are made heavyer & large cross section to take up heavy load during body .
Planer tools may be solides forged are bit type .
The materials is are used for planer tools are HHS , cemented carbides .
The tools used in a planer machine are mention below
(1) straight roughing tool .
(2) Round nose tool .
(3) Square nose finishing tool .
(4) Gooseneck finishing tool .
(5) Left hand dovetail end cutting roughing tool for cast iron.
(6) For Conner .
(7) Roughing flat surface rool
(8) Finishing .
(9) slide cutting tool .
CLAMPING OF WORK THROUGH SKETCH .
A Planer table is used to hold very large and heavy workpiece may be held on a planer table by flowing methods by standard clamping by spacial fixture .
Standard clamping are used for holding most of the workpiece on a planer table.
The standard clamping device are
(1) Heavy duty vices
(2) T - Bolt & clamp
(3) Stet blocks
(4) poppets & to edogs
(5) Angle plates
(6) Planer jacks
(7) Planer centers
(8) Stop
(9) V - blocks
The standard clamping device are

(6) Planer jacks
(7) Planer centers
(8) Stop
(9) V - blocks
Heavy duty vices .
A planer vice is much more heavier in construction the a shaper vice.
The workpiece clamp between the fixed movebul jaw .
The vice me be plane are swivelled base type .
The workpiece clamp between the fixed movebul jaw .
The vice me be plane are swivelled base type .
T - Bolt & clamp .
Most of the work piece are clamped directly on the table by T bolt & clamped
Different types of clamped are used for different types work.
Stet block .
Stet block are used to give support other and of the clamped .
Work piece of different hight me be supported by using different Stet blocks .
Poppets & to edogs
These are used for holding very thin pieces of work on a planer table.
Angle plates .
These are used for holding L shaped work piece.
Planer jacks .
These are used for supporting the over hanging parts of a work to prevent it from bending .
Planer centres .
The planer centres these are used for holding the work piece between two centres .
Stops .
These are used prevent the work piece from moving end wise & sideways under thrust of the cut .
V - blocks .
These are used for holding the round workpiece .
