Everything thing you need to know about slotter machine

The slotter machine is one the oldest machine tool that exists, 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 guideway 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, and application as well as advantages and disadvantages.

Slotting machine definition:

A slotting machine is defined as a reciprocating machine tool that is used to remove unwanted material chips from the workpiece. It is used to produce paths like splines, grooves, and more, the machine is also known as a 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:

Advantages

The following stated below represent the benefits of a slotter machine:

• The single-point cutting tool is used.
• Low-cost machine.
• Accurate surface finish.
• High machine efficiency.
• Low maintenance.
• The machine is light.

Disadvantages

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 the slotter machine is very similar to the shaper machine. Their major difference is that shaper machines work 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 takes effect on the rotation of the 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 taken to the workpiece. The worktable is designed to be adjusted and has 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 upstroke and there is no cut in the return stroke.

Specification of cutting machines:

The specifications of a slotting machine are depended on several factors which include:

• Power input.
• Maximum table drive.
• Type of drive.
• The maximum length of ram stroke.
• A number of feeds.
• Table feed.
• A number of speeds.
• Floor space requirement.
• kW of the motor.
• The diameter of the worktable in MM.

Slotter machine operations:

Slotting machines 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.
