Main parts of shaper machine :
Base :
The base is the main body of the machine. It consist of all elements of the machine. The bed may be rigidly bolted to the floor of the shop or on the bench according to the size of the machine.
The base is made of cast iron to resist vibration and take up high compression load.
Column :
The Column is a box it can be mounted upon the base.
It provides the housing for the crank slider mechanism and also encloses the ram driving mechanism.
Two accurately guideways are provided on the top of the column on which the ram reciprocates.
Crossrail :
The Crossrail is mounted on the front vertical guideways of the column.
A horizontal cross feed screw which is fitted within the Crossrail and parallel to the top guideways of the column.
It attaches with some cross-movement mechanism.
Saddle :
The saddle is mounted on the Crossrail which holds the table firmly on its top.
Crosswise movement of the saddle by rotating the crossfeed screw by hand or by the power to move sideways.
Clapper Box :
The Clapper box carries the tool holder.
It provides clearance for the tool in return stroke.
It also prevents the cutting edge dragging the work piece while return stroke and prevents tool wear.
Table :
The table is bolted to the saddle receives crosswise and vertical movements from the saddle and Crossrail. It is the metal body attached over the frame.
The main function of the table is to hold the work piece and vice over it.
T slots which used to clamp vice and work piece over it.
Ram :
Ram is the main part of shaper machine.
The ram is a reciprocating member of shaper machine.
Ram is semi-cylindrical in shape and heavily ribbed inside to make it more rigid.
Ram is made by cast iron and moves over ways on the column.
It attached by the rocker arm which provide it motion in the crank driven machine and if the machine is hydraulically driven it attached by hydraulic housing.
Toolhead :
Toolhead is situated at the front of the ram.
The main function of it is to hold the cutting tool.
The cutting tool can be adjusted on it by some of the clamps.
Stroke adjuster :
It is attached below the table.
It is used to control the stroke length which further controls the ram movement.
Table supports :
These are attached front side of the table and used to support the weight of the table during working.
