Differences between Shaper and Planer Machines

Shaper machine and Planer Machine
Comparison between shaper and planer machines is given below in the tabular form.

S.no
Shaper
Planer
1In 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.
2Shaper 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.
3A shaper is a light machine.A planer is a heavy duty machine.
4Shaper can employ light cuts and finer feed.Planer can employ heavier cuts and coarse feed.
5Shaper uses one cutting tool at a time.Planer uses several tools to cut simultaneously.
6The shaper is driven using quick return mechanism.The drive on the planer table is either by gears or by hydraulic means.
7It 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.
