Slotter machine is applied

Vertical shaper machine is also known as slotter in a workshop but the fundamental difference between vertical shaper and slotter is that the frame of vertical shaper is fixed and cannot be tilted whereas the frame of slotter can be tilted at any angle. The small angle may be given to tool to the vertical…

Constructional detail of shaper is shown in Figure 19.25. Following are the parts of the shaper machine. Figure 19.25 Constructional Details of Shaper Base: Base is made of grey cast iron to absorb the vibration and it is bolted to shop floor. Column: It is housing of ram, quick return mechanism, and table. A ram reciprocates on the top of…

Shaping and planning are the oldest methods of machining. They are seldom used in production and have been replaced by milling and broaching. The major difference between two is that, in shaping the reciprocating or cutting motion is provided to the tool and the feed is given to the workpiece, whereas in planning, it is…

Shaper and planer are very old machine tools. They are used to produce a plane surface, inclined surface, and slots. But due to consumption of excess time, they are replaced by milling machines in large production. In shaper, cutting tool is provided reciprocation motion and job is provided only feed motion. Normally, forward stroke is…

Turning is a metal removal process in which job is given rotational motion while the cutting tool is given linear (feed and depth of cut) motion. Different types of turning operations are mentioned as follows: Straight Turning: It is the operation of producing a cylindrical surface of a job by removing excess material. In this operation,…

A number of cutting operations are performed on a lathe machine. Therefore, various cutting tools are used in lathe such as left-hand and right-hand turning tools, facing tools, threading tools, parting-off tool, etc., as shown in Figure 19.10. Figure 19.10 Various Cutting Tools Used in Lathe

A lathe machine consists of a number of components. These components perform various functions, for example, facilitate variation in speed, hold the cutting tool, rigidly hold the job, provide end support to the job, automatic movement of tool, etc. A lathe with nomenclature of various parts is shown in Figure 19.5. Figure 19.5 A Lathe with Nomenclature…

Lathe machine can be specified by following dimensions (Figure 19.4): Figure 19.4 Specifications of Lathe

According to the construction and design lathe can be classified as follows: Bench Lathe: It is small in size and mounted on a separate table. It has all the attachments, which a larger lathe has. It is used to perform a precise work. Speed Lathe: This may be bench type or legs supported lathe. It has no…
