What is the shaper machine?

What is the shaper machine?

The shaper machine is a reciprocating type of machine basically used for producing the horizontal, vertical or flat surfaces. The shaper holds the single point cutting tool in ram and workpiece is fixed in the table. During the return stroke, No metal is cutting.

What is the working of shaper machine?

A shaper machine is working on the following principle: No metal is cut during its return stroke is called an Idle stroke. The feed is given at the end of the cutting stroke. Generally, the cutting stroke is carried out at slow speed and the idle stroke is carried at high speed with the help of quick return mechanism.

What are the types of shaper machine?

Types of Shaper Machine

• Contour shaper.
• Universal shaper.
• Standard shaper.
• Draw cut shaper.
• Horizontal shaper.
• Crank shaper.
• Vertical shaper.
• Hydraulic shaper.

What is the ratio of shaper machine?

Although the ratio varies somewhat, several shapers have a linkage using 220 degrees of the cycle for the cutting stroke and 140 degrees for the return stroke. This is close to a 3:2 ratio.

What is the function of RAM in shaper machine?

Ram is the main part of the shaper machine. Ram is made with cast iron and slide left and right in the guideway of the column. It holds the tool and provides reciprocating motion to it.

What is the function of clapper box in shaper machine?

Clapper box: It carries the tool holder. The main function of clapper box is to provide clearance for tool in return stock. It prevents the cutting edge dragging the work piece while return stock and prevent tool wear.

How many type of shaper are there?

Various types of shaping machines are classified into four such as motion type (driving mechanism), ram travel, table design, and the type of cutting stroke: Types of shaper machine base on driving mechanism: Crank type e.g. quick return motion mechanism. Geared shaper type.

How do you classify a shaper?

A shaper is a type of machine tool that uses linear relative motion between the workpiece and a single-point cutting tool to machine a linear toolpath. Its cut is analogous to that of a lathe, except that it is (archetypally) linear instead of helical.

What is the formula of shaper?

Explanation: (n*l* (m+1)) – It is the right formula for calculating the cutting speed.

What kind of machine is a shaper machine?

The Shaper Machine 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.

When is the feed given in a shaper machine?

The feed is given at the end of the cutting stroke. Generally, the cutting stroke is carried out at slow speed and the idle stroke is carried at high speed with the help of quick return mechanism. In the shaper machine, there is another mechanism called Quick return Motion Mechanism.

What is the return mechanism of a shaper machine?

As above stated, in the shaper machine the mechanism that dominated the entire process is “Quick return mechanism”. The reciprocating motion of the ram and the above mentioned quick-return mechanism is obtained with the help of the combination of the below four mechanisms:

How does the head of a shaper work?

The tool head is in the clapper box, which causes cutting action only in a forward stroke of the ram. The feed or depth of cut of the tool is given by down feed screw. In short, The shaper works on the principle of the Quick return motion mechanism.
