The direction of motion of tool is called feed. The machine tool that ‘s used to remove unwanted metals from the work piece to give the desired shape and size so called ” Lathe machine “. It can be moved along the bed either towards or away from the headstock. Main Parts Of Lathe Machine. • Chuck: allows the mounting of difficult workpieces that are not round, square or triangular. Head stock 3. These machines have a milling column rising up above the lathe bed, and they utilize the carriage and topslide as the X and Y axes for the milling column. The part of the lathe on the carriage that allows for angular adjustment of the cutting tool. The following part of Lathe serves as housing for the driving pulleys and back gears . OUTLINE OF PRESENTATION 1. Parts of Lathe Machine are Bed, Legs, Headstock, apron, Tailstock, Spindle, Saddle, Tool Post, Carriage, Cross-slide, Tool Rest. Lathes are used in woodturning, metalworking, metal spinning, thermal spraying, parts reclamation, and glass-working.Lathes can be used to shape pottery, the best-known design being the Potter's wheel.Most suitably equipped metalworking lathes can also be used to produce most solids of revolution, plane surfaces and screw threads or helices. Names of lathe parts. 01.Headstock. The dial tells you when to engage the half nut lever so the tool follows the same thread groove every time. It is used to get the required shape and size of the job. Operates the Cross-slide across (or perpendicular to) the bed. Among other things, it can be used to cut, sand and turn workpieces. This can avoid shutdowns and unfinished projects. Feed Mechanism 6. shows the different parts of engine lathe or central lathe. Bed 8 7.
