While the turret lathe in it's perfected form is now a complete machine, the turret idea was first applied to engine lathes, and turret attachments are so universally popular that most of the lathe manufacturers now make them of dimensions suitable for their lathes, and attach them either to the lathe carriage or to a special bed which may be fastened to the lathe bed upon the removal of the tail-stock. A great variety of work may be done in the turret lathe, its principal rival being the automatic screw machine, whose economy lies principally in the fact that one operator may take care of a number of machines, each of these machines depending principally for their success upon the turret with its multiplicity of tools. And this idea of a turret carrying from four to eight tools is applied in a great variety of ways and to a large variety of machines on account of the ease with which any desired tool may be brought into a working position.
The head-stock of a turret lathe is made in several ways, from that of a plain head withoutback gears to one with a large variety of speeds, controlled by handles operating clutches, or friction driving devices, or both, and which may be operated while the machine is in motion. In some cases the head-stock is cast in one piece with the bed, in others fitted to it in a similar manner to that of an ordinary lathe. In still others the head has a transverse movement on the bed upon which it slides and its movement is easily controlled by the operator.
The turret is designed and constructed in a variety of forms, but principally either circular or hexagonal. It is mounted usually in a horizontal position, that is with its axis vertical, but still in some of the best machines, notably the Gisholt, it is pivoted in an inclined position, the object being to bring the long tools, made necessary by a large machine, up out of the way of the operator as they swing over the front of the machine.
Is determined by length of lathe machine. And is determined by the diameter of the workpiece.

A lathe machine is specified by-1.The maximum diameter of the workpiece that can be operated on the machine.2.The distance between the headstock and the tail-stock of the machine.3.The length of bed of the machine.
The lathe is Specified on the basis on the following factors: 1.Lathe swing or simply swing i.e maximum diameter of the workpiece that can be machined. 2.Maximum distance between the HEadstock and tailstock. 3.Length of the bed. then there are many kinds of lathe categorized by their specific functions or mechanisms but these are the general specifications for every lathe.
the size of a lathe can be described by either of the following ways. 1.DISTANCE BETWEEN THE TWO SPINDLES. 2.SWING DIAMETER.ITS THE DISTANCE MEASURED FROM THE SADDLE/CARRIAGE TO THE CENTRE OF THE SPINDLE.

Pitch measurement refers to the distance from one thread to the next when threads are cut on a lathe. Different threads have different pitches and a lathe can be set to to cut to any specified pitch. This is achieved by selecting the pitch and engaging the lead screw on levers located on the headstock, then engaging the half-nut around the lead screw from the apron. With the correct threading tool inserted threads can be cut into the workpiece.
