A slotter machine is one the oldest machine tool that exist, which was invented for BRUNEL. It is much similar to the vertical shaper machines as the ram carrying the slotting tool reciprocates in a vertical guide-way of the machine. This machine can produce flat and contour surfaces, slots and internal grooves.
Today we’ll be looking at the definition, diagram, parts, mechanism, types, operations, specification, application as well as advantages and disadvantages.

Slotting machine definition:
Slotting machine is defined as a reciprocating machine tool that is use to remove unwanted material chips from the workpiece. It is used to produce path like splines, grooves and more, the machine is also known as vertical shaper machine.
Slotting Machine Applications:
The following stated below are the applications of a slotter machine:
- Slotters are used for light cuts.
- Used can perfectly cut slots, spline, and internal and external keyways.
- Can produce internal and external gears.
- Ability to produce internal blind holes.
Advantages and disadvantages of a slotting machine:
The following stated below represent the benefits of a slotter machine:
- Single-point cutting tool is used.
- Low-cost machine.
- Accurate surface finish.
- High machine efficiency.
- Low maintenance.
- The machine is light.
Despite the good advantages of a slotting machine some limitations still occur. The following stated below are the disadvantages of slotting machines:
- Required a skillful person to operate it.
- Rigid in construction.
Working principle of a slotter machine:
The working of slotter machine is very similar with the shaper machine. Their major difference is that shaper machines works horizontally whereas slotter machines work vertically. The ram is connected to the crank and the crank is connected to the gears. This allows the increase or decrease of the gear speed and take effect on the rotation of crank speed. It also allows the ram to move up and down.
The workpiece is attached to the workable and the ram will be manually taking to the workpiece. The worktable is design to be adjusted and have the workpiece clamp on it. the crank rotates as soon as power is supply the machine and the crank is connected to the ram which moves up and down.
During the up and down movement of the ram, the cutting stroke occurs in the up stroke and there is no cut in the return stroke.

Slotter machine mechanism:
The following stated below are the two different slotter machine mechanism:
- Hydraulic Drive (greater speed flexibility, smoother operation, stroke length can be adjusted)
- Variable Speed Motor Drive (multi-speed arrangement)
Slotter machine parts:
A slotter machine consists of these following parts:
- Rotating or Circular table
- Ram and tool head
- Ram drive
- Feed drive
Types of slotter machine:
Slotter machines can be categorized into these four types:
- Punch slotter.
- Precision toolroom slotter.
- Production slotter. and
- Special purpose slotter machine.

Specification of scotting machines:
The specifications of a slotting machine is depended on the several factors which include:
- Power input.
- Maximum table drive.
- Type of drive.
- The maximum length of ram stroke.
- Number of feed.
- Table feed.
- Number of speed.
- Floor space requirement.
- kW of motor.
- The diameter of the worktable in MM.
Slotter machine operations:
Slotting machine can be used to produce various operations like:
- Internal and external circular surfaces.
- Bling holes internal machining.
- Internal and external flat surface machining.
- Shaping internal and external forms of profiles.
- Internal recess of circular, semi-circular, concave and convex surfaces.
- Irregular surface machining.
- Dies and punches operation.
- Slots grooves, splines, and internal and external keyways surface.
- Internal and external gear teeth.
