These lathes are used for mass production of identical parts. Since the entire operation is automatic, these lathes require little attention from the operator. The automatic lathes are so designed that the tools are automatically fed to the work and withdrawn after all the operations are completed to finish the work.Cutting operations are automatically controlled by a sequencer of some form. The lathe in which the workpiece is automatically fed and removed without the use of an operator.This is used for small work usually requiring considerable accuracy such as in the production of gauges, punches, and beds for press tools.Ī lathe that can follow a template to copy a shape or contour.All the types of operation can be performed on this lathe that may be done on an ordinary speed or engine lathe.
The bench lathe is so small that it can be mounted on a bench. By using the attachments and accessories, other operations such as taper turning, Drilling, milling, and grinding may also be performed. Usage: It is used for producing cylindrical components.In geared-Head lathe the gear ratio (Spindle speed to motor speed) is changed by Speed- Lever.The speed changes in belt drive are obtained by shifting the belt to different steps of a cone pulley.In Belt driven lathe, Power from the motor is transmitted to the spindle by belt drive, In Geared head lathe power from the motor is transmitted to the spindle by the gear drive.The engine lathe, depending upon the design of the headstock for receiving power, may be classified as belt-driven lathe, motor-driven lathe, and geared head lathe.The cutting tool may be fed both in cross and longitudinal direction concerning the lathe axis with the help of a carriage.It differs from a speed lathe that it has an additional mechanism for controlling the spindle speed and for supporting and controlling the feed of fixed cutting tool.The main parts of engine lathe are the bed, headstock, tailstock, carriage, lead screw, and feed change gearbox.It is a general-purpose lathe and is widely used in workshops.
