SLOTTER MACHINE

The slotter or slotting machine is also a reciprocating type of machine tool similar to a shaper or a planer. It may be considered as a vertical shaper. The chief difference between a shaper and a slotter is the direction of the cutting action. The machine operates in a manner similar to the shaper, however, the tool moves vertically rather than in a horizontal direction. The job is held stationary. The slotter has a vertical ram and a hand or power operated rotary table.

A slotter is a very economical machine tool when used for certain classes of work given as under.

(i) It is used for machining vertical surfaces

(ii) It is used angular or inclined surfaces

(iii) It is used It is used to cut slots, splines keyways for both internal and external jobs such as machining internal and external gears,

(iv) It is used for works as machining concave, circular, semi-circular and convex surfaces

(v) It is used for shaping internal and external forms or profiles

(vi) It is used for machining of shapes which are difficult to produce on shaper

(vii) It is used for internal machining of blind holes

(viii) It is used for machining dies and punches, and

Since a slotter works slowly. It has less use in mass production work. It can be substituted by the broaching machine.
