Before discussing about the difference between the shaper planer and slotter machine let us first understand each machine in detail.
Shaper Machine:
Just like Lathe and Milling machines, the Shaper machine is also one of the reciprocating types of machine. The shaper machine is compact and easy to use. The tool used in this machine is called a single-point cutting tool. In this machine, either a tool or job reciprocates, while the other tool or job gives intermittent linear feed during machining. Shaping machine is suitable for machining of small jobs, generally up to 900mm size cubical block. This machine can create a flat surface on both horizontal, vertical, angular, and contoured surfaces.
Planer Machine:
The planer machine is also a reciprocating type of machine tool like a shaper. The table has T-slots for mounting the workpiece, and also provide with guideways so that we can move the work-piece accordingly. In the planer machine, generally the tool is in the fixed position. We have to move the workpiece for machining different surfaces. The planer machine is suitable for big castings, heavy forging, etc.
Slotter Machine:
A slotting machine is similar to a vertical shaper machine. The ram carries the slotting tool and reciprocates over the job. This machine is used for producing slots, flat, contour surfaces, keyholes, internal grooves, etc.
Differences between the Shaper Machine, Planner Machine, and Slotter Machine:
| SHAPER | PLANER | SLOTTER |
| This is lighter, smaller and cheaper. | These are heavier, larger and costlier. | These are lighter, Smaller and Cheaper. |
| Low machining accuracy. | High machining accuracy. | Low machining accuracy. |
| The rate of power consumption is low. | Power consumption is High. | The rate of power consumption is low. |
| Not possible to make deep cuts and heavy feeds. | Possible to make deep cuts and heavy feeds. | In Slotter, it is not Possible to make deep cuts and heavy feeds. |
| Intended for small Jobs. | Intended for large Jobs. | Intended for small Jobs. |
| It Requires Less Floor Space. | It Requires Large Floor Space. | It Requires Less Floor Space. |
| In Shaper, The tool is moving and work is Stationary. | The tool is Stationary and work is moving. | The tool is moving and work is Stationary. |
| Usually, only one tool is used on a shaper. | It permits machining of more than one surface at a time. | Only one tool is used for machining. |
| Tools used are Lighter and Smaller. | Heavier, Stronger and Larger tools are used. | Tools used are Lighter and Smaller. |
| Work Setting requires less Skill and less time. | Requires more skill and more time. | Work Setting requires less Skill and less time. |
