LATHE MACHINE
What is lathe machine? A lathe is a machine tool which rotates the workpiece on its axis to perform various operations such as cutting, knurling, drilling, or deformation,facing, turning, with tools that are applied to the workpiece to create an object which has symmetry about an axis of rotation.
Explanation of the standard components of most lathes • Bed: Usually made of cast iron. Provides a heavy rigid frame on which all the main components are mounted. • Ways: Inner and outer guide rails that are precision machined parallel to assure accuracy of movement. • Headstock: mounted in a fixed position on the inner ways, usually at the left end. Using a chuck, it rotates the work. • Gearbox: inside the headstock, providing multiple speeds with a geometric ratio by moving levers.
• Spindle: Hole through the headstock to which bar stock can be fed, which allows shafts that are up to 2 times the length between lathe centers to be worked on one end at a time. • Chuck: 3-jaw (self centering) or 4-jaw (independent) to clamp part being machined. • Chuck: allows the mounting of difficult workpieces that are not round, square or triangular. • Tailstock: Fits on the inner ways of the bed and can slide towards any position the headstock to fit the length of the work piece. An optional taper turning attachment would be mounted to it.
