The Shaper Machine: Parts, Functions, and Working Mechanism

What Is the Shaper Machine?

As the name suggests, shaper machines are used to give different sizes to the workpiece. Shaper machines are commonly used to produce flat surfaces, grooves, slots, etc.

In the shaper machine, a single-point cutting tool has used that retrieves and rubs the workpieces and removes unwanted metal from the workpieces in the form of chips.

The workpiece shaper machine has an adjustable tool post by the grip. A single-point cuttings tool is in reciprocating motion that rubs the workpiece and cuts off unwanted metal in the form of chips.

It consists of several important parts which take proper care of it. These are ram, table, clappers box, tool head, column, cross rail, stroke adjustment, table support, base, etc. The shaper machine operates on a quick return single crank mechanism that provides recrossing motion to the tool.

Parts of Shaper Machine:

The Main Parts of the Shaper Machines Are:-

Step – 1. Basis

1. As the name suggests, this is the basis of the shaper machine.
2. All other parts of the machine exist on this basis.
3. The base is built with cast iron capable of taking all the compressive load by various parts of the machine. The shock-absorbing capacity of the base is high.

Step – 2. Column

1. The pillar is present above the base and is attached to the base.
2. It is also made of cast irons and is box-like in shape.
3. The column serves as the casing of drive mechanism components such as gear mechanisms, pulleys, etc., and also supports reciprocating RAM and the workforce.

Step – 3. Guidelines

1. Two directions are given at the top and side of the column.
2. Ram rotates on a guideway, which is present at the top of the column, and the table moves up and down in another guideway, which is present at the edge of the column.

Step – 4. Table support

Table sliding support is present near the base in front of the table that supports the table while slidings up and down the path of the column.

Step – 5. Table

1. The table is a metal body that slides up and down the direction passage of the column.
2. The main function of the table is to hold the workpiece, and the vice president is placed on this table.
3. The table is in the shape of the box, and the T-slots are cut on the table in such a way that the vice of any machine can be fitted on that T-slot and fit properly into it.

Step – 6. Vice President

1. The vice is present on the table and is used to hold or fasten the workpiece properly.
2. The vice has two jaws, one movable and the other fixed.
3. One of the jaws is movable, so workpieces of different sizes can be fastened between the two jaws.

Step – 7. Ram

1. Ram shaper is the main part of the machine.
2. The ram is built to the left and right in the guideway of the column with cast iron and slides.
3. It holds the device and gives it a reciprocating motion.
4. In a crank-driven machine, the ram is attached to the rotating arm, which speeds up the ram.
5. In a hydraulic driven machine, the ram is connected with a hydraulic housing that accelerates the ram.
6. The single-point cutting tool is used as a tool in a shaper machine that is usually made of high speed steel or sometimes high carbon steel.

Step – 8. Tool head or vertical slide

1. It can move up & down with the help of handles. 
2. Also, it can be rotated at any angle.
3. The handles of the tool head are called the tool feed handle.

Step – 9. Clapper Box

1. The Clapper Box helps the tool to fit inside the tool posts.
2. The main function of the clappers box is to provide clearance for the tool in the return stroke.
3. It also prevents the cutting edge from being pulled on the workpiece in the return stock and prevents tool wear.

Step – 10. Ram clamp

The ram clamp is used to determine the position of the ram.

Step – 11. Toolpost

Tool posts are used to properly place and manipulate tools. Shaper machine has two types of traversing wheels. They: –

#1. Hand traversing wheel

Hand traversing wheels are used to move the table up and down.

#2. Crossfeed handle

1. Crossfeed handles are used to feed the tool in the forward and backward direction.
2. While the hand traversings wheel helps to move the table up and down, the crossfeed handle helps the table move in the cross direction.

Working of Shaper Machine:

The shopper machine operates on a quick return mechanism. It is used to shape metal or to create flat surfaces, grooves, and slots. It cuts the metals in one stroke in the backward or fifth motion, and the rest becomes useless. Shaper machine work can be described as follows.

1. First, the work is fixed on the machine’s table.
2. The single-point cuttings tool is mounted on a tool post located on the ram.
3. Now the motor starts manually, which causes the rotating speed of the RAM by a quick return mechanism.
4. When the ram is in reciprocating motions, the tool rubs the workpiece, removing unwanted material. It cuts the metal in a forward shock.
5. Whereas in the return stroke, the clapper provides clearance between the tool and the workpiece, which ensures that there is no cutting in the return stroke.
6. If the tool cuts the material both front and back, it eliminates the corroded surface and also causes tool wear.

Frequently asked questions (FAQs) about shaper machines:

What is a shaper machine used for?

A shaper machine is primarily used to produce flat surfaces, grooves, slots, and other shapes on metal workpieces. It uses a single-point cutting tool to remove material in a controlled manner.

What are the main parts of a shaper machine?

The main parts include the base, column, ram, table, tool head (or vertical slide), clapper box, tool post, and various guiding mechanisms. Each part plays a crucial role in the machine’s operation and stability.

How does a shaper machine work?

The shaper machine operates on a quick return mechanism. During the cutting stroke, the ram carrying the tool moves forward, cutting into the workpiece. On the return stroke, the tool clears the workpiece to prevent damage and excessive wear.

What materials can be shaped using a shaper machine?

Shaper machines are typically used on metals such as steel, cast iron, aluminum, and brass. They can handle a variety of workpiece sizes and shapes within their capacity.

What are the advantages of using a shaper machine?

Advantages include the ability to create precise flat surfaces and shapes, relatively simple operation, and suitability for smaller production runs or prototype work. It also allows for customization of tool paths and cutting profiles.

Are there different types of shaper machines?

While basic shaper machines operate on similar principles, variations include hydraulic shapers for smoother operation and CNC shapers for automated control over cutting parameters. These variations cater to different production needs and complexities.

How is tool wear managed in a shaper machine?

Tool wear is managed through proper selection of cutting tools (typically high-speed steel or carbide), appropriate feeds and speeds, and regular maintenance of tool edges. The clapper box mechanism also helps prevent excessive wear during the return stroke.

What safety precautions should be followed when using a shaper machine?

Safety precautions include wearing appropriate protective gear (goggles, gloves), securing workpieces firmly on the table or vice, ensuring the machine is properly lubricated and maintained, and following correct operating procedures to prevent accidents.

Can a shaper machine handle large workpieces?

Shaper machines vary in size and capacity, with larger models capable of handling relatively large workpieces. However, they are typically used for smaller to medium-sized components due to their design and operational constraints.

Where are shaper machines commonly used?

Shaper machines are found in workshops, tool rooms, and manufacturing facilities where precision shaping of metal components is required. They are often used alongside other machining tools like milling machines and lathes to complete manufacturing processes.
