Classification of Automatic Lathes

Classification of Automatic Lathes

Classification of Automatic Lathes - Automatic lathes can be classified as follows:

(i) Single spindle automatics,

(ii) Multi spindle automatics,

(iii) Bar stock machines,

(iv) Chucking machines,

(v) Horizontal spindle machines,

(vi) Vertical spindle machines.

Single spindle automatics have only one spindle and they machine one component at a time.

Multi spindle automatics have more then one spindles (4 to 8). These machines are either of parallel action type or of  progressive action type. Multi spindle machines have higher production rate as compared to single spindle machines.

Bar stock machines use-work material in the form of bar and produce components such as bushes, nuts, screws, rings etc.

Chucking machines hold castings or forgings in the chuck or in special fixtures for machining them.

Horizontal spindle machines have their spindle in the horizontal position.

Vertical spindle machines have their spindle in vertical position. They occupy less floor space as compared to horizontal spindle machines.

The majority of these machines are operated mechanically by trips and cams, which, with the gearing, control the spindle speeds, strokes and other aspects of the cycle.
