Parts of Lathe Machine

A metal lathe or metalworking lathe is a large class of lathes designed for precisely machining relatively hard materials. They were originally designed to machine metals; however, with the advent of plastics and other materials, and with their inherent versatility, they are used in a wide range of applications, and a broad range of materials. In machining jargon, where the larger context is already understood, they are usually simply called lathes, or else referred to by more-specific subtype names (toolroom lathe, turret lathe, etc.). These rigid machine tools remove material from a rotating workpiece via the (typically linear) movements of various cutting tools, such as tool bits and drill bits.

Apron:
Front part of the carriage assembly in which the carriage handwheel is mounted.

Carriage: The carriage consisting of three main parts, the saddle, cross-slide, and apron, is used to move the cutting tool along the lathe bed. The saddle, an H-shaped casting mounted on the top of the lathe ways, provides a means of mounting the cross-slide and apron.

Compound Slide Rest: Movable platform on which the tool post is mounted; can be set at an angle to the workpiece. Also known as compound slide and compound rest.

Counter Shaft: It is also called as Jack Shaft. It is used to change the rpm of the motor.

Headstock: The main casting mounted on the left end of the bed , in which the spindle is mounted. Houses the spindle speed change gears. Bed: The bed is a heavy, rugged casting made to support the working part of the lathe. On its top section are machined ways that guide and align the major parts of the lathe.
Lead Screw: Precision screw that runs the length of the bed. Used to drive the carriage under power for turning and thread cutting operations. Smaller lead screws are used within the cross-slide and
