AUTOMATIC LATHE
This is closely related to the centre lathe in some features but differs in the sense that they are machine tools in which the parts are machined automatically.The working process is fully automatic that is repeated to produce many parts without the direct involvement of the operator.Both the working and non-working are performed in a definite sequence by the control system adopted in the automatic which is set up to suit given project.In real sense,no lathe machine is totally automatic because,it requires the presence of the operator to load the machine for a batch of parts and also to initiate each lathe operation.
Classification of Automatic Lathe Machine
There are various ways of classifying the automatic lathes;
(a)Depending upon the type of work machined,these include
(i)Magazine loaded Automatics. These machine are used for producing component from accurate separate blanks.They are also called ‘Automatic chucking machine’.
(ii)Automatic bar Machine.Automatic bar machine are designed for machining components from bar or pipe stock.These machines are mainly used for the manufacture of quality fasteners(screws,nuts and studs),bushings,shafts,rings,rollers,handles and other parts,usually made of bar or pipe stock.
(b)Depending upon the number of work spindles,these include
(i)Single Spindle Automatics.The general purpose single spindle automatic lathes are widely used for quantity or mass production by machining of high quality fasteners;bolts,srews,studs e.t.c.,bushings,pins ,shafts,rollers,handles and similar small metallic parts from long bars or tubes of regular section and also often from separate small blanks.They are preferably and essentially used for large volume of production i.e mass production,they are used always for producing jobs of rod,tubular or ring type and of relatively smaller size,they run fully
