History

Shapers have been largely superseded by milling machines or grinding machines in modern industrial practice. They rapidly fell out of favour with modern industry as they were time consuming in operation, the amount of material removal by a single point cutting tool being no match for recent methods, however they are still popular with some amateurs, or where production time is not a factor. The basic function of the machine is still sound and tooling for them is minimal and very cheap to reproduce. The mechanically operated machines are simple and robust in construction, making their repair and upkeep easily achievable. A Milling machine is a power-driven machine used for the complex shaping of metal (or possibly other materials) parts. ... Rotating abrasive wheel on a bench grinder. ... A tool bit generally refers to a plain High Speed Steel (HSS) tool. ...


Types

They may be vertical or horizontal, with the horizontal arrangement being the most common. Vertical shapers are generally fitted with a rotary table to enable curved surfaces to be machined. The vertical shaper differs to a slotter (slotting machine) as the slide can be moved from the vertical, a slotter is fixed in the one plane. 10 inch, manual rotary table A rotary table is a precision work positioning device used in metalworking. ...


Very small machines have been successfully made to operate by hand power. Once size increases, up to a potential 36 inch stroke, the power needs increase and it becomes necessary to use an electric motor. This motor drives a mechanical arrangement (using a pinion gear, bull gear and crank) or a hydraulic motor which supplies the necessary movement via hydraulic cylinders.


Operation

Shaper linkage. Note the drive arm revolves less for the return stroke than for the cutting stroke, resulting in a quicker return stroke and more powerful cutting stroke.
Shaper linkage. Note the drive arm revolves less for the return stroke than for the cutting stroke, resulting in a quicker return stroke and more powerful cutting stroke.

A shaper operates by moving a hardened cutting tool backwards and forwards across the workpiece. On the return stroke of the ram the tool is lifted clear of the workpiece, reducing the cutting action to one direction only.

The workpiece mounts on a rigid, box shaped table in front of the machine. The height of the table can be adjusted to suit this workpiece, and the table can traverse sideways underneath the reciprocating tool which is mounted on the ram, the table motion is usually under the control of an automatic feed mechanism which acts on the feedscrew. The ram slides back and forth above the work, at the front end of the ram is a vertical tool-slide that may be adjusted to either side of the vertical plane. This tool-slide holds the clapper box and toolpost from where the tool can be positioned to cut the straight, flat surface on the top of the workpiece. The tool-slide permits feeding the tool downwards to put on a cut it or may be set away from the vertical plane, as required. Screws come in a variety of shapes and sizes for different purposes. ...


The ram is adjustable for stroke and, due to the geometry of the linkage, it retracts faster on the return (non-cutting) stroke than on the forward, cutting stroke. This action is via a slotted link or whitworth link.


Cutting fluid may be employed to improve the finish and prolong the tools life. Cutting fluid or coolant is liquid used to cool and lubricate the cutting edges of machine tools and the pieces they are shaping. ...


Uses

The most common use is to machine straight, flat surfaces but with ingenuity and some accessories a wide range of work can be done. Other examples of its use are:

  • Keyways in the boss of a pulley or gear can be machined without resorting to a dedicated broaching setup.
  • Dovetail slides

A pulley is a wheel with a groove along its edge, for holding a rope or cable. ... Spur gears found on a piece of farm equipment. ... A push style 5/16 keyway broach A broach is a series of chisel points mounted on one piece of steel. ...

shaper / router table comparison (1483 words)
The shaper motors are likely to be rated for constant use and are capable of taking much bigger cuts than would ever be attempted with a router.
Shapers usually come with adequate fences with dust collection ports and hold down devices; most of these items are added cost extras for router tables.
Depending upon the motor size of the shaper the overall operation may be a little better on the shaper though due to a potential significant difference in available torque.
