The main job of both shapers and planers is to remove material to make shapes and surfaces that you want. However, they are very different in how they are built, how they work, and what they can be used for. The primary difference is that the planer machine produces flat surfaces by linear motion cutting, whereas the shaper machine shapes flat surfaces by reciprocating cutting action.
Well, in this reading, we’ll explore what a shaper and planer machine are and the differences between shaper and planer machines, discovering things they have in common and things that set them apart.
Let’s begin!
What is a Shaper Machine?
A shaper machine is a type of precision machining tool that is mainly used to create smooth, curved surfaces on metal or other material workpieces. It works by reciprocating a linear motion to remove material. The cutting tool is the main part of a shaper; it is positioned atop a ram that oscillates. A clamp holds the workpiece securely to a table. As the ram operates, the cutting tool removes material from the workpiece, shaping it as needed.
The shaper machine can be used for any of the following applications:
- Creating smooth and curved surfaces on metal parts.
- Crafting engine parts and brake drums for use in automobiles.
- Producing slots, grooves, and keyways in metal parts.
- Producing dies and tooling for a wide range of sectors.
- Making gear teeth, both internal and external.
- Machining intricate profiles and shapes from steel and aluminium.
- Restoring or fixing metal surfaces that have been worn or damaged.
- Fabricating specialized components for custom machinery.
- Creating chamfers and notches in engineering parts.
- Manufacturing mechanical components with a high degree of precision, such as dovetail slides.
What is a Planer Machine?
A planer machine is a heavy-duty, precision machine tool used to shape and level large, flat surfaces on metal or other workpieces. It works similarly to a shaper but is made specifically to handle heavier and larger workpieces. A planer’s main component is a cutting tool that is fixed on a table and mounted on a horizontal crossrail. The cutting tool removes material to produce a smooth and level surface by moving along the length of the workpiece in a linear, reciprocating motion.
The planer machine can be used for any of the following applications:
- Working on massive components for the aerospace and shipbuilding industry.
- Producing precise, parallel surfaces on materials such as cast iron and steel.
- Machining heavy machinery parts, like guideways and machine beds.
- Manufacturing components for industrial equipment and machinery.
- High-precision machining in the heavy engineering industries.
- Fabricating parts for construction equipment and infrastructure.
- Large metal workpieces are smoothed and flattened on their surface.
- Restoring and repairing worn or damaged surfaces on large components.
Difference Between Shaper and Planer Machine
All operations performed in planning machines can be executed in the shaping machine. The extended stroke length, increased dimensions, and enhanced rigidity allow planning machines to perform more substantial tasks on extensive projects and their elongated surfaces.
It generates planes and flat surfaces using a single-point cutting tool. Compared to a shaper machine, a planer machine is larger and more massive. The planer is capable of machining heavy workpieces, which cannot be accomplished on a shaper surface.
The significant difference between shaper and planer machine are presented in the table below:
| 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 the workpiece travels back and forth under the tool. |
| 2 | Shapers 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 meters 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 | Shapers can employ light cuts and finer feed. | Planers 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 a 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 the better rigidity of the planer machine, compared to that of a shaper, the planer can give more accuracy on machined surfaces. |
