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, vivid 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 (toolbar lathe, turret lathe, etc. These rigid machine tools remove material from a rotating workforce 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 handheld 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-peeped casting mounted on the top of the lathe ways, provides a means of mounting the Ross-slide and apron, Compound Slide Rest: Movable platform on which the tool post is mounted; can be set at an angle to the workforce.
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 compound to move those parts by precise amounts. Saddle: A casting, shaped like an “H” when viewed from above, which rides along the ways. Along with the apron, it’s one of the two main components that make up the carriage.
Tail stock: The tailcoats can be adjusted for taper or parallel turning by two screw set in the base. The tailcoats spindle can be locked in any position along the bed Of the lathe by the tailcoats clamp. The tailcoats spindle has an internal taper to receive the dead center, Which provides support for the right-hand end Of the job. The tailcoats hand wheel moves the tailcoats spindle in or out of the tailcoats casting. It can also be used to provide a hand feed for drilling and reaming operations.
