Comparison between shaper and planer machines is given below in the tabular form.
| S.no |
Shaper
|
Planer
|
|---|---|---|
| 1 | In a shaper machine work is held stationary and the cutting tool on the ram is moved back and forth across the work. | In a planar machine, the tool is stationary and work piece travels back and forth under the tool. |
| 2 | Shaper can be used for shaping much smaller jobs. | A planer is meant for larger jobs than can be undertaken on a shaper. Jobs as large as 6 meter wide and twice as long can be machined on a planer. |
| 3 | A shaper is a light machine. | A planer is a heavy duty machine. |
| 4 | Shaper can employ light cuts and finer feed. | Planer can employ heavier cuts and coarse feed. |
| 5 | Shaper uses one cutting tool at a time. | Planer uses several tools to cut simultaneously. |
| 6 | The shaper is driven using quick return mechanism. | The drive on the planer table is either by gears or by hydraulic means. |
| 7 | It is less rigid and less robust. | Due to better rigidity of planer machine, compared to that of a shaper, planer can give more accuracy on machined surfaces. |
