Difference Between Shaper , Planer, Slotter.

Shaping Machine 

  1. The work is held stationary and  the tool on the ram is moved back and forth across the work.
  2. Used for shaping much smaller jobs
  3. It is a light machine.
  4. Can employ light cuts and finer feed.
  5. Uses one cutting tool at a time.
  6. Driven using quick- return link mechanism.
  7. It is less rigid and less robust.

Planing Machine:

  1. The tool is stationary and the workpiece on the table travels back and forth under the tool.
  2. Meant for much larger  jobs. Jobs as large as 6 metre wide and twice as long can be machined.
  3. It is a heavy duty machine.
  4. Can employ heavier cuts and coarse feed.
  5. Several tools can cut simultaneously.
  6. The drive on the planer table is either by gears or by hydraulic means.
  7. Better rigidity that give more accuracy on machined surfaces.

Slotting Machine:

  1. The work is held stationary and the tool on the ram is moved up and down across the work.
  2. It is used for making slots in smaller jobs.
  3. Slotting is light machine.
  4. Can employ light cuts and finer feed.
  5. Shaper uses one cutting tool at a time.
  6. The rams are either crank-driven  or hydraulically driven.
  7. It is less rigid and less robust.
