Hello, readers in today's article, we will learn how a shaper machine works also we learn about the parts, types, operations, specifications, advantages disadvantages, and applications of a shaper machine.
So let's start with the definition of a shaper machine.
Shaper Machine Definition:
The ShaperMachine is a reciprocating type of machine tool basically used to produce Horizontal, Vertical or Inclined flat surfaces by means of straight-line reciprocating single-point cutting tools similar to those which is used in lathe operation.
The flat surface produced may be horizontal, vertical or inclined at an angle
Working Principle of Shaper Machine:
A shaper machine is working on the following principle:
For a shallow cut the apron may be set vertical but if the curve is quite sharp, the apron in swiveled towards the right or left away from the surface to be cut.
Parts of a Shaper Machine with Function:
The Base is designed to take the entire load of the machine tool and it is bolted to the floor of the shop.
This is made of grey cast iron to resist vibration and to take the compressive load.
The column is a Box like casting made up of cast iron and mounted on a base.
It is provided with accurately machined guideways on the top on which the ram reciprocates.
The guideways are also provided on the front vertical face for the movement of cross rail. The column encloses the ram driving mechanism.
The cross rail is mounted on the ground vertical guideways of the column.
It consists of two parallel guideways on its top perpendicular to the ram axis is called as a saddle to move the table in crosswise direction by means of a feed screw.
The table can be raised or lowered to accommodate different sizes of the job by rotating elevating screw which causes the cross rail to slide up and down on the vertical face of the column.
It is mounted on the cross rail to hold the table firmly on its top.
The crosswise movement of the saddle causes the table to move crosswise direction by rotating the crossfeed screw.
It is mounted on the saddle.
It can be moved crosswise by rotating the crossfeed rod and vertically by rotating the elevating screw.
The table is a box-like casting with accurately machined top and side surfaces. These surfaces having t-slots for clamping the work.
In Universal shaper, the table may be swiveled on a horizontal axis and its upper part may be tilted up or down.
In heavy Shaper, the front face of the table is supported by adjustable table support to give more rigidity.
It is a reciprocating member of the shaper which holds the tool and the reciprocates on the guideways on the top of the column by means of quick return motion mechanism.
It houses the screwed shaft for altering the position of the RAM with respect to the work. The RAM is in semi-cylindrical form and heavily ribbed inside to make it more rigid.
The tool head holds the cutting tool firmly and provides both vertical and angular movement to the tool with the help of a down feed screw handle.
The head allows the tool to have an automatic relief during the return stroke.
The vertical slide of a tool head consists of a swivel base which is graduated in degrees. So, the vertical slide can set at any angle with the work surface.
The amount of feed or depth of cut may be adjusted by a micrometer dial on top of the down feed screw.
A tool head again consists of:
Clapper box and clapper block
Apron consisting of clapper box and tool post is clamped on the vertical slide by the screw.
The apron Can be swiveled upon the apron swivel pin towards left or right.
The clapper box houses the clapper block by means of a hinge pin.
The tool post is mounted on the clapper block.
During forwarding cutting stroke the clapper block keeps the rigid support to the tool by fitting securely into clapper box and while returning stroke the tools slide over the work by lifting, the block out of clapper boxes shown in the above figure
The below diagram is shown the principal parts of the Shaper Machine:
Specification of Shaper Machine:
The specification of shaper machine depends upon the following:
The maximum length of stroke ram.
Types of the drive ( Crank, Gear and Hydraulic type)
If you have any queries or doubts about the Shaper machine, you can ask me in the comment section and also you can join our facebook group. I will love to hear from you and glad to help you. Till then enjoy rest your day. Cheers
In this article, I'm going discuss about Steam Condenser in briefly. At the end of this article, you will learn How a Steam Condenser works, Definition and Types of a steam condenser, and more.

Today in this article I am going to give you an in-depth overview of Electron Beam Welding Machine. This Welding Process was first developed in 1949 by Karl-Heinz Steigerwald who was a German physicist. In this article first, we will see the Definition, How it's Work after that I'll also show you the Applications, Advantages, […]
In the field of mechanical engineering, the Extrusion Process is widely used by the engineers to form an object which has a fixed cross-sectional area. For making the object, the raw material is pushed into a die to provide it with the desired shape. The major function of this process is that the brittle materials […]
