SLOTTER

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.

PRINCIPLE PARTS OF A SLOTTER

Fig. shows a slotter and its various parts. The main parts of a slotter are discussed as under:

Bed or Base

It is made up of cast iron. It supports column, tables, ram, driving mechanism etc. The top of the bed carries horizontal ways along which the worktable can traverse.

Table

It holds the work piece and is adjustable in longitudinal and cross-wise directions. The table can be rotated about its centre.

Hand wheels

They are provided for rotating the table and for longitudinal and cross traverse.

Column is the vertical member

They are made up of cast iron and it houses the driving mechanism. The vertical front face of the column is accurately finished for providing ways along which the ram moves up and down.

Ram

It is provided to reciprocate vertically up and down. At its bottom, it carries the cutting tool. It is similar to the ram of a shaper; but it is more massive and moves vertically, at right angle to the worktable, instead of having the horizontal motion of a shaper:

Cross-slide

It can be moved parallel to the face of the column. The circular work-table is mounted on the top of the cross-slide.
